Details
Product designers and manufacturers increasingly rely on thermoplastic elastomer (TPE) material solutions to produce and deliver highly durable and high-quality soft touch parts. Compared to the thermoplastic polyurethane (TPU) materials traditionally used for soft-touch manufacturing, TPEs offer better resistance to warpage and fatigue, as well as better protection against UV, chemical, and oil exposure.Benefits
- Broad tactile properties with superior touch and feel
- Broadest operating temperature range from -45°C to 150°C
- High tear and abrasion resistance
- High fatigue endurance after 255 compression cycles
