Automotive Molded Polyurethane Cushion Foam Core for Driver Seats

This molded polyurethane driver backrest foam core is an OEM flame-certified cushioning component designed for passenger vehicle seat backrests. Manufactured using precision one-piece molding processes to match ergonomic back contours, it can be mounted directly onto seat back frames or paired with matching seat cushion foams to form complete automotive seating padding systems. It meets mandatory global OEM interior safety and flammability regulations.

Key Features & Selling Points:
- Superior Mechanical Resilience: Features high tensile strength (≥ 110 kPa), tear resistance (≥ 1.9 N/mm), and high rebound resilience (≥ 60%) to support drivers during daily operation.
- Long-Term Durability & Fatigue Resistance: Maintains < 5% residual deformation after 1,000,000 cyclic fatigue tests and ≤ 4% compression set, preventing backrest collapse over years of use.
- Eco-Friendly Halogen-Free Flame Retardancy: Formulated with liquid phosphorus flame retardants that self-extinguish rapidly without dripping, meeting GB 8410-2017 and FMVSS 302 standards.
- Precision One-Piece Molded Ergonomics: Accurately molded to support proper spine posture, reduce driving fatigue, and fit seamlessly onto factory seat frames.
