With its advanced thermoplastic composites, OEMs are successfully incorporating our thermoplastic composite technology and gaining value from our design expertise at every step of the product development cycle," said Advanced Composites portfolio offers both thermoplastic and thermoset composite solutions with exceptional strength-to-weight ratios.

Versaflex™ Thermoplastic Elastomers provided reliable sealing and bonding for HVAC thumb wheel and vent in automobile Versaflex™ Thermoplastic Elastomer provided flexibility and various environmental factors for seat belt tether cover Versaflex™ Thermoplastic Elastomers provided excellent sealing and overmolding for seat ventilation tube

The initiative, sponsored by Avient Design, a highly specialized group of industrial designers and project engineers at Avient Corporation, began in September 2024, focusing on mentoring students in designing with Avient’s Polystrand™ thermoplastic composite materials, leading to the development of a range of innovative and practical product concepts. The six-week project is aimed to harness the distinctive properties of Avient’s Polystrand thermoplastic composites, including their strength, durability, and lightweight characteristics, to create cutting-edge designs for the sporting goods industry. The final presentations showcased a diverse array of innovative product concepts that effectively leveraged the properties of Polystrand continuous glass-fiber reinforced thermoplastic composites.

In line with the continuing drive towards greater sustainability and circularity in the industry, we will demonstrate our latest advances in materials science at Chinaplas, from specialty colorants and color prediction to bio-based thermoplastic elastomers (TPEs) and engineered materials,” says Say-Eng Lee, Vice President and General Manager, Color & Additives Asia for Avient. reSound™ BIO Thermoplastic Elastomers (TPEs): formulated with 35 to 75 percent bio-renewable feedstock without compromising property retention, adhesion strength in overmolding applications, or colorability. Versaflex™ CE 3130 Series TPEs: a range of non-blooming thermoplastic elastomers for demanding consumer electronics, automotive, and appliance applications requiring premium surface finish, enhanced feel, and improved aesthetics with UV, stain, abrasion, and scratch resistance.
