These new grades contain 35 to 75 percent bio content, validated using ASTM C6866-21 method B.

The new reSound™ NF bio-filled grades are based on polymers such as polypropylene (PP) with 15 to 20 percent bio-based filler.

The OnFlex TPE material serves as an impermeable elastic membrane, reducing air leakage by 95 percent compared to standard electrical installation boxes, and leads to energy savings for Schneider’s customers.

Testing under ASTM D3389 proved that this new material delivers 40 percent better abrasion resistance than a leading competitor’s product, as well as incumbent GLS nylon overmolding grades.

Polymers used for laser welding must allow a minimum 20 percent transmission rate for laser energy.

This represents a performance improvement of up to one-hundred percent over Avient’s previous generation of additives which have been the leading solutions in fiber industry. 

In contrast, the bio-derived grade offers greenhouse gas emissions at 2.35 kg CO2e / kg product, a nearly 25 percent lower cradle-to-gate product carbon footprint (PCF) than Avient’s standard Versaflex HC BT218 grade.

OnFlex LO, PolyOne’s newest ground-breaking TPE technology, reduces volatile organic compounds (VOCs) by up to 50 percent versus existing TPEs, and minimizes fogging and odor in interior automotive components.

These PA6-based Nymax REC formulations contain between 20 and 100 percent recycled content from registered sources approved by the European Union regulation for Registration, Evaluation, Authorization, and Restriction of Chemicals (REACH), such as recycled textiles.
