Q1: What is the primary application domain for Hyundai EP7065B/8901 TPE?
A: Hyundai EP7065B/8901 TPE is a thermoplastic elastomer specifically engineered for soft-touch overmolding and functional sealing applications in automotive interior components, consumer electronics housings, and medical device grips — where balanced elasticity, processability, and surface aesthetics are critical.
Q2: Is EP7065B/8901 compatible with common engineering thermoplastics like PP, ABS, or PC?
A: Yes, EP7065B/8901 exhibits strong adhesion to polypropylene (PP) and ABS substrates without requiring primers or surface treatment under standard two-shot injection molding conditions. Compatibility with polycarbonate (PC) may require process optimization and is typically evaluated case-by-case.
Q3: What processing methods are recommended for this TPE grade?
A: EP7065B/8901 is optimized for injection molding and two-component (2K) overmolding. It performs well on standard screw-type injection molding machines with moderate melt temperatures and short residence times. Extrusion is possible but less common and requires careful thermal management to preserve elasticity.
Q4: How does EP7065B/8901 perform under elevated temperature exposure?
A: This TPE maintains dimensional stability and tactile integrity up to approximately 70–80 °C during short-term service. Prolonged exposure above 85 °C may lead to gradual softening or compression set increase, so thermal design margins should be considered for continuous-use applications.
