Q1: What is the primary application domain for Hyundai EP1370B/8901 TPE?
A: Hyundai EP1370B/8901 TPE is primarily engineered for soft-touch overmolding and functional elastomeric components in automotive interior systems, including control knobs, gear shift boots, and trim accents requiring consistent tactile response and long-term dimensional stability.
Q2: Is this grade suitable for two-shot injection molding with common thermoplastics?
A: Yes — EP1370B/8901 TPE exhibits strong adhesion to polypropylene (PP), polyethylene (PE), and ABS substrates without requiring primers or surface treatment under standard processing conditions, making it well-suited for two-shot and multi-material molding processes.
Q3: How does this TPE perform under elevated temperature exposure typical in automotive cabins?
A: The formulation offers enhanced thermal resistance compared to conventional SEBS-based TPEs, maintaining elasticity and surface integrity during prolonged exposure to temperatures commonly encountered in vehicle interiors (e.g., dashboard environments), with minimal compression set and reduced tendency to bloom or soften.
Q4: What are the key processing advantages of EP1370B/8901 TPE?
A: It features a relatively low melt viscosity and narrow processing window, enabling short cycle times, excellent flow into fine details, and reduced risk of flashing — particularly beneficial for high-precision automotive parts with tight tolerances and complex geometries.
