FAQ

What's the difference between TPE, TPU, and TPV materials?

TPE is the umbrella term for thermoplastic elastomers. TPU (thermoplastic polyurethane) offers excellent chemical resistance and abrasion resistance. TPV (thermoplastic vulcanizate) provides rubber-like properties with thermoplastic processability. TPE also includes styrenic block copolymers (SEBS) ideal for soft-touch applications.

How do I select the right Shore hardness for my application?

Shore hardness affects flexibility, durability, and sealing performance. Softer materials (30-60A) provide better sealing and tactile feel but lower tear strength. Harder materials (70A-60D) offer better structural support and wear resistance. Consider your application's stress requirements and user interaction needs.

Can TPE materials be overmolded without primers or adhesion promoters?

Many TPE grades bond well to rigid substrates like PP, PC, and ABS without primers, but success depends on the specific TPE chemistry, substrate material, and processing conditions. SEBS-based TPEs typically offer the best adhesion properties. Always test adhesion with your specific material combination.

What are the main limitations of TPE compared to silicone rubber?

TPEs generally have lower continuous use temperatures (typically 100-120°C vs 200°C+ for silicone), limited chemical resistance to polar solvents, and may have compression set issues in demanding applications. However, TPEs offer easier processing, better mechanical properties, and recyclability advantages.
