Qingdao Guanshan Industry Launches New High-Performance Semi-Closed Cell EPDM Foam Series
Specialty polymer supplier Qingdao Guanshan Industry announces the official release of its new Semi-Closed Cell EPDM Foam series. Blending open and closed-cell traits, this line delivers efficient sealing, cushioning, and thermal insulation solutions for automotive, HVAC, and electronics industries.
Key Advantages
High Strength & Resilience: Tensile strength > 3 MPa, elongation > 120%, and compression set ≤ 5%, ensuring long-lasting sealing durability.
Wide Temperature Range: Operates reliably from -56℃ to +121℃, handling extreme environments effortlessly.
Thermal Insulation & Fire Safety: Thermal conductivity < 0.038 W/(m·K); compliant with FMVSS 302 and UL94 HBF standards.
Superior Weatherability: Excellent ozone resistance (48H / 200pphm) and UV stability preventing aging.
