The environmental benefits of these new epoxy resins are certified by an independent organization – the International EPD Consortium (IEC) from Sweden. This product obtained the Environmental Product Declaration (EPD) certificate for grades CHS-EPOXY G 520, CHSEPOXY G 525 and CHS-EPOXY G 530.Green epoxy resins are produced in the company’s plant from glycerinebased epichlorhydrin. These resins have indisputable environmental benefits and enable customers to significantly reduce their environmental impact. This technology offers a range of environmentally-friendly solutions that meet customers’ needs for eco-alternatives to conventional materials by reducing the overall environmental impact of the final product. Green epoxy resins are based on renewable resources (reduced consumption of fossil resources) and significantly less carbon dioxide is emitted during their production compared to conventional production technology (reduced carbon footprint). They are chemically indistinguishable from propylene-based conventional epoxy resins and can be used in the same huge range of applications such as wind energy, composites, automotive, electro-industry, coatings, etc.

Lightweight construction is gaining attention – and not only in the automotive industry. Bumpers, fenders, roof, and car interiors – every kilo stripped is golden profit. Less weight means more kilometres with the same battery charge or tank of gas. To better address the needs of this huge market, organic sheets can be used with resin laminated products. Short fibres can be used in plastics, as well as glass mat reinforced thermoplastics (GMT) or organic sheets, as a flat support and finally inserted with continuous filament according to predetermined laying patterns. Weberit uses a virtual test station to simulate the working life of a plastic part and then determine where exactly to place the continuous filaments to provide the best effect where it is most needed. «Strength & force just in place.» This means setting continuous filaments in the right place along the lines of force where they work during the product lifetime. This way, it is possible to shed further weight. Weberit Werke Dräbing GmbH (Oberlahr, Germany) has developed a method whereby conventional glass mat thermoplastics (GMT) and organic sheets can be cost-effectively overmoulded with additional functional elements of reinforcing fibre strands. With this new process (patent pending), fibre strands of different materials such as glass, carbon, aramid or basalt are inserted along the lines of force. This method provides much higher resistance than conventional short-fibre reinforced plastics and achieves higher stiffness and strength. This significantly facilitates industrial processing due to shorter cycle times.
