Hyundai EP1065BM/8901 TPE – Frequently Asked Questions (FAQ)

Q1: What is the primary application domain for Hyundai EP1065BM/8901 TPE?

A: Hyundai EP1065BM/8901 TPE is a thermoplastic elastomer engineered for soft-touch overmolding applications—particularly in automotive interior components such as control knobs, gear shift boots, and dashboard trims—where balanced processability, surface aesthetics, and long-term elasticity are required.

Q2: Is this grade suitable for two-shot injection molding with polypropylene (PP) or ABS substrates?

A: Yes, EP1065BM/8901 TPE exhibits good adhesion to common rigid thermoplastics including PP and ABS when processed under optimized mold temperature, melt temperature, and residence time conditions. Surface treatment of the substrate is generally not required, though compatibility should be confirmed via prototype trials.

Q3: How does this TPE perform under elevated temperature and UV exposure typical in automotive interiors?

A: EP1065BM/8901 TPE offers enhanced thermal stability and improved UV resistance compared to standard SEBS-based TPEs, supporting long-term service in non-direct-sunlight interior environments. For extended outdoor or high-UV applications, supplemental stabilization or top-coating may be recommended.

Q4: What are the key processing recommendations for optimal part quality?

A: Recommended melt temperature ranges from 180 °C to 220 °C, with mold temperatures between 30 °C and 50 °C. Drying is advised prior to processing—typically at 70 °C for 2–4 hours—to minimize surface defects. Injection speed and packing pressure should be adjusted to avoid jetting or sink marks, especially in thin-wall overmolded sections.
