Q1: What is the primary application domain for Hyundai EP7050B/8901 TPE?
A: Hyundai EP7050B/8901 TPE is a thermoplastic elastomer engineered for soft-touch overmolding and functional sealing applications, commonly used in automotive interior components, consumer electronics housings, and industrial grips where resilience, processability, and surface aesthetics are critical.
Q2: Is this grade compatible with polypropylene (PP) and ABS substrates?
A: Yes — EP7050B/8901 TPE is specifically formulated to achieve strong adhesion to common thermoplastics such as PP and ABS without requiring primers or surface treatment, making it well-suited for two-shot injection molding processes.
Q3: What processing conditions are recommended for optimal flow and surface finish?
A: Standard injection molding parameters apply: melt temperature typically ranges from 180 °C to 220 °C, mold temperature between 20 °C and 50 °C. Drying is recommended at 60–70 °C for 2–4 hours prior to processing to ensure consistent rheology and minimize surface defects.
Q4: Does this TPE grade contain halogens or heavy metals?
A: No — Hyundai EP7050B/8901 TPE is formulated to be halogen-free and complies with global restrictions on heavy metals, supporting compliance requirements for RoHS and similar environmental directives.
Q5: How should EP7050B/8901 be stored to maintain long-term stability?
A: Store in original sealed packaging in a cool, dry, and well-ventilated area away from direct sunlight and sources of heat or humidity. Under these conditions, shelf life is typically 12 months from date of manufacture.
