Grand Largue Composites and Sicomin enable flax-fibre-built Racing Yacht

Fibres, fabrics, epoxy resins and adhesives from Sicomin have been used by Grand Largue Composites (GLC) to construct the first Class40 racing yacht to feature a significant quantity of flax-fibre reinforcements.
The yacht, called Crosscall, won the Class40 World Championships in June 2022 and is a prototype of the new Lift V2 design by Marc Lombard, one of the leading naval architects in this field.

Class40 is one of the most competitive fleets in yacht racing. The hulls of Class40 yachts must be light in weight, strong and stiff, and durable in the most extreme of conditions. Furthermore, to keep costs down, they cannot be reinforced with carbon fibres. The quality and reliability of the resins used for the infusion and lamination of the hulls are therefore of paramount importance.

Class40 is one of the most competitive fleets in yacht racing. The hulls of Class40 yachts must be light in weight, strong and stiff, and durable in the most extreme of conditions. Furthermore, to keep costs down, they cannot be reinforced with carbon fibres. The quality and reliability of the resins used for the infusion and lamination of the hulls are therefore of paramount importance.

Crosscall's cockpit was designed to be effectively non-structural, with the mainsheet, which can generate huge shock loads, supported separately. This would allow the cockpit to be made from a hybrid biaxial fabric comprising 50% flax fibres. Other parts of the boat that incorporate flax fibre include the tunnel, the engine cover, the ballast tanks and the cap. The rest of the boat is reinforced with 100% glass-fibre fabrics.

To help it realise this ambitious design, GLC, an infusion specialist, turned to its long-time material supplier, Sicomin. The hull was moulded and infused in one piece and the deck – including the hybrid flax-fibre cockpit – was also infused as a single part. The internal structure was then laminated into the hull by hand before the hull and deck were finally bonded together.

The infusion resin selected was Sicomin’s SR 1710, a high-modulus structural epoxy. Designed specifically for use in infusion and injection processes, it has exceptionally low viscosity and its low-reactivity hardener makes it suitable for the production of large parts. Composites components made from SR 1710 possess high interlaminar shear-strength and the resin retains its mechanical properties in wet environments.

Sicomin’s low-toxicity SR 8200 was used to laminate the internal structures onto the skin of the hull. Ideal for hand laminating, this system includes a choice of hardeners with a wide range of reactivities, which makes it equally suitable for making large or small parts. The hull and deck were joined together with Sicomin’s Isobond SR 7100, which demonstrates high fatigue strength and is very resistant to microcracking.

An epoxy bonding primer – called Undercoat EP 215 HB+ and supplied by Sicomin’s sister company, Map Yachting – was applied to the moulds first to make demoulding easier. It also serves as an undercoat in the polyurethane exterior paint system that is used instead of gelcoat to protect the epoxy hull from UV damage.

Since the launch of Crosscall, GLC has started building a second Lift V2 Class40 and a third one is now planned, both for which Sicomin will supply the materials.

Freudenberg: Elastic superabsorbers for wound dressings

Freudenberg Performance Materials (Freudenberg) has launched an elastic variant of its flexible superabsorbers for modern wound dressings. These superabsorbers increase the comfort level for patients as well as enabling longer wear time, thus reducing the frequency of dressing changes. Freudenberg is debuting the elastic superabsorbers at this year’s Compamed in Düsseldorf, from November 14 – 17, 2022. Further highlights at the trade fair include components for more sustainable wound care, PU foams with directly applied silicone adhesives, and an innovative hydrophilic debridement foam.

Freudenberg uses a new technology to manufacture the elastic superabsorbers. Unlike other methods, this technology does not perforate or slit the material, thus achieving a high degree of consistent elasticity. Furthermore, the technology used by Freudenberg bonds the superabsorbent fibers more uniformly with the material, thus enhancing the integrity of this layer in the wound dressing.

The Borvida portfolio will offer base chemicals or cracker products (such as ethylene, propylene, butene and phenol) with ISCC Plus-certified sustainable content from Borealis sites in Finland, Sweden and Belgium. The move is part of Borealis’ broader commitment to a Future-Positive Revolution, in which the unrivalled benefits of base chemicals and polymers can be enjoyed at minimal impact to the planet.   

The portfolio will initially comprise Borvida B, from non-food waste biomass, and Borvida C, from chemically-recycled waste. In the future, the range will evolve to include Borvida A, sourced from atmospheric carbon capture. Borvida is complementary and is the building block to Bornewables™, a portfolio of polyolefins based on renewably-sourced second generation feedstocks, and Borcycle™, which offers circular polyolefins produced from mechanically- and chemically-recycled plastic waste.

Borealis produces a wide range of base chemicals for use in numerous industries based on various feedstock, such as naphtha, butane, propane and ethane. Through its olefin units (steam cracker and propane dehydrogenation), it converts these into the building blocks of the chemical industry: ethylene, propylene and C4 hydrocarbons (butylenes, ethyl tertiary-butyl ether (ETBE) and butadiene), and C5-6 hydrocarbons (pygas, phenol) among others.

The basis of the Borvida portfolio is Mass Balance, a Chain of Custody model that enables sustainable content to be tracked, traced, and verified through the entire value chain, offering sustainability-assured products from feedstock to end product. Using this model, circular alternatives can be offered in a cost-effective and environmentally-conscious way, which can be scaled up quickly without compromising on quality or efficiency.

Borvida can be used for a wide range of different polymer and chemical applications, also beyond polyolefins (PO). Non-PO polymers, such as polycarbonates, acrylonitrile butadiene styrene (ABS), super absorbant polymer (SAP) and other chemicals, are utilised for various end applications including coatings, plasticizers, adhesives, automotive, electronics, lubricants, detergents, appliances and sports equipment.

Together with key strategic partners, including Neste and Covestro, Borealis strives to provide a long-term solution in order to allow value-chain partners to meet their sustainability goals. Borvida will enable our customers to increase the sustainability of their products, keeping them ahead of forthcoming legislative changes, and meeting their customers’ demands for climate-conscious products.

Introduced on a smaller scale in early 2020, early renewable base chemicals customers include Covestro. “The use of alternative sustainable raw materials is one important pillar of our strategic ambition to become fully circular”, comments Frank Dörner, Managing Director Covestro Procurement Services GmbH & Co. KG. “The new product line is a good example for joint solutions, another strategic pillar, in order to establish new and reliable supply chains creating benefits for our customers.”

The Oerlikon Barmag eccentric screw pump
02.06.2022

Oerlikon Barmag presents innovations at the ACHEMA 2022

Focus on eccentric screw pumps and pumps for shear-sensitive materials

Improved productivity and increased lifespan and tailored solutions also for the most demanding applications within the chemicals and plastics industries and in PUR applications – these are the convincing arguments with which Oerlikon Barmag is showcasing its precision metering pumps at this year’s ACHEMA between August 22 and 26, 2022 in Frankfurt. The focus is on the new pump for shear-sensitive conveying media and the new eccentric screw pump.

Focus on eccentric screw pumps and pumps for shear-sensitive materials

Improved productivity and increased lifespan and tailored solutions also for the most demanding applications within the chemicals and plastics industries and in PUR applications – these are the convincing arguments with which Oerlikon Barmag is showcasing its precision metering pumps at this year’s ACHEMA between August 22 and 26, 2022 in Frankfurt. The focus is on the new pump for shear-sensitive conveying media and the new eccentric screw pump.

Eccentric screw pumps – robust all-rounders convey any medium
The requirements for pumps are considerable, as the demand for customized solutions for increasingly complex processes is rising. This is particularly true for Oerlikon Barmag’s new eccentric screw pump range. High wear-resistance, increased durability and robust operation – the new pump is tailor-made for conveying highly-filled, high-viscosity and abrasive media, such as filled adhesives, filled silicones and filled casting compounds, for example. The is the multi-stage seal system, which considerably increases the pump’s lifespan. The upstream shaft sealing ring protects the slide ring seal against excessively-fast wear caused by challenging media. In turn, the optimum alignment of the drive shaft – ball bearing-supported and centrally-guided through the shaft sealing ring – prevents any metal debris caused by friction and hence ensures considerably greater durability. Producers benefit from considerably greater productivity, as the pumps’ maintenance intervals and hence machine downtimes are significantly reduced.

New pump for shear-sensitive materials
For increasingly complex customer-specific process solutions, Oerlikon Barmag is now expanding its GA series, developed especially for the challenging conveying of high-viscosity media, to include the GAB51F for shear-sensitive conveying media. The newly-developed pump with its viscosity range of max. 300 Pas is tailored to conveying high-viscosity, shear-sensitive materials such as adhesives and silicones, for example. “The shear forces impacting the medium within the pump are reduced to a minimum as a result of a specially geometry”, explains Thorsten Wagener, Senior Sales Manager within the Pump Construction business unit. The material is conveyed through the pump in an as gentle and low-pulsation manner as possible and metered precisely at the outlet – ensuring it retains its characteristic properties.

High-speed metering pump with sealed product space
The high-speed metering pump has been especially developed for metering poorly-lubricating media. Here, the main benefit is the sealed product space, which extends the pump’s lifespan considerably. The space that comes into contact with the media is limited to the area around the gears. “As a result, the high-speed pump is particularly suited for applications in the chemicals industry, which frequently involve aggressive acids”, comments Thorsten Wagener.

GM series for low-viscosity media
The pumps in the GM and GA series provide precision metering with low-pulsation feeding of the conveying medium. The multi-stage GM pump conveys low-viscosity media (i.e. 250 bar, 100 mPas) even under high pressure and in the most challenging conditions. The square design from the proven GM series is the standard pump for many metering tasks. The development of the multi-stage pump expands the applications range for the GM series considerably. The round 2-stage GM pump has been developed especially for use in high-pressure technology. It masters the particular challenge of conveying small throughputs with low viscosities. The pump is perfect for 0.05 through 20 cm³/rev feed sizes and is excellently suited for use in high-pressure machines for PUR molded parts, foam slab stock, refrigeration unit insulations and sandwich panels, for example.

GA series pumps for high-viscosity media
The Oerlikon Barmag GA range has been especially developed for the challenging conveying of media with higher viscosities. The GA series pumps are available for conveying volumes of between 1.25 and -30 cm³/rev (0.6-144 l/h). They have been designed for pressures of up to 200 bar, for viscosities of up to 1.500 Pas as well as for temperatures of up to max. 225 °C. With this range of pumps, Oerlikon Barmag offers its customers tailor-made solutions for many technical processes in which high-precision and even metering is of paramount importance.

The drum pump – conveying and metering using a single unit
With the drum pump, the Oerlikon Barmag pump specialists have created a pump designed specifically for conveying and metering high-viscosity materials such as adhesives, silicones and other high-viscosity materials from drums and other large containers and for pressures of up to 250 bar. Its special features not only include the fact that it removes high-viscosity materials from the drum, but that it also meters the medium directly without any additional interim stops.
