nent tests and numeric calculations, the level of stress that the recyclate could withstand was compared with the stress capacity identified in the sample tests. This revealed that the recyclate had the structural durability to withstand the cyclic load exerted on the component during operation. Offering more sustainable products across the

entire product range is one of the aims for Avient, with the latest example an extension of its Gravi- Tech density-modified portfolio to include more grades based on recycled and bio-based resin and/or filler. The company says performance is not sacrificed. Gravi-Tech density modified formulations were originally developed to mimic the luxurious look, weight, and feel of die-cast or machined metals by using select metallic fillers. The company says that they are a cost-effective alternative to metal and are useful for applications in luxury packaging and consumer goods including caps and closures for cosmetics, bottle caps and boxes for spirits, and decorative knobs and grips for appliances, furni- ture, and automotive applications. The Gravi-Tech REC recycled formulations are based on recycled resin and/or filler from post- industrial recycled (PIR) and/or post-consumer recycled (PCR) sources. Gravi-Tech BIO bio-based formulations contain bio-based resin from renew- able plant sources. Both families are developed to offer comparable performance to conventional density-modified solutions. ReDefyne is a range of PA compounds from Ascend Performance Materials containing up to 100% pre and post-consumer recycled PA6 or PA66. The grades are said to provide a lower carbon footprint and reliable performance, even in demanding applications. ReDefyne products are third-party certified and Ascend is partnering with ITW Global Fasteners to pilot blockchain traceabil- ity through Plastic Finder’s Certified Circular Plastic
programme. With ReDefyne, ITW is producing fasteners with a considerably lower carbon footprint.
Composite options New additions to the Lanxess Tepex thermoplastic composites product line include grades made from recycled or bio-based raw materials. One uses a matrix polymer based on PA6 produced from cyclohexane containing over 80% sustainable raw materials. Another new product line comprises vari- ants of Tepex containing recycled carbon fibres from post-consumer and post-industrial waste. The fibres are used as non-woven material or as chopped fibre mats. A variety of thermoplastics are suitable as the matrix material, Including PA6, PA66, PP and PC. The latest addition to the Teknor Apex range of thermoplastic vulcanisates (TPVs) is Sarlink R2 3180B. Based on its existing Sarlink technology, the new grade incorporates 25% post-industrial recycled (PIR) content. It is described as a pre-col- oured black, high-durometer multi-purpose TPV that is essentially a functional equivalent of its virgin counterpart in terms of processing and performance. According to the company, Sarlink TPVs typically provide faster cycle times and throughput rates when compared with competitor products and this advantage is retained in the recycled content version. The company has also developed its Monprene
TPEs, which contain 25-35% recycled content (sourced from domestic, commercial and industrial waste streams) and are available in a light, natural colour rather than the more usual black. This allows product designers considering using recycled materials considerably more freedom. Monprene
