Typical spiral flow lengths for GLS TPEs* 30-32 Softer SEBS formulations (below 30 Shore A) will shrink more than harder materials.

GLS™ TPE AUTOMOTIVE SOLUTIONS ENABLE LONG-TERM PERFORMANCE WITH TPEs FOR FASTENERS AND CLIPS The average length of vehicle ownership is on the rise, placing greater demands on all elastomeric materials to maintain long-term sealing performance in fasteners and clips.

Drying is not typically required for GLS TPEs. 75- 90°F (25- 32°C) Harder grades (> 50 Shore A) will set up faster in the mold compared to very soft grades (< 20 Shore A).
