GAINING TRACTION WITH WET GRIP SOLUTION CASE STUDY: GLS™ THERMOPLASTIC ELASTOMERS Challe nge Accepted. WET GRIP TECHNOLOGY PROVIDES POWERFUL SOLUTION FOR SURFCO HAWAII © 2021, All Rights Reserved Avient Corporation, 33587 Walker Road, Avon Lake, Ohio USA 44012 1 Wax Mat® is a trademark of SurfCo Hawaii, Inc. THE SOLUTION Working collaboratively with SurfCo and its manufacturer and processor, Avient set to work on developing a polymeric, wet grip technology.

We saw an untapped market opportunity for improved seat fastening solutions and recognized that continuing to use bent steel plate would hold us back,” said Hagen Spiess, Senior Design Engineer at HellermannTyton. THE SOLUTION Avient recommended Bergamid™ B70 G30H black TM-X PA 6 resin with 30 percent glass fiber reinforcement for its excellent mechanical properties and cost benefits. The new seat securement part has already been adopted by one OEM customer, and we are confident that other manufacturers will come to us for this lightweight, cost-efficient solution.”
