Based on the saturated structure characteristics of the ethylene propylene diene monomer (EPDM) rubber molecular chain, Taiya, through precise regulation of the molecular chain structure and unique reinforcing technology, endows EPDM foam with the following breakthrough properties:
l Ultra-wide temperature range adaptability: Maintains performance stability under operating conditions from -40℃ to 120℃, and retains excellent performance after thermal aging
Outstanding weather and corrosion resistance: It has passed 3,000 hours of ultraviolet aging and 1,000 hours of ozone aging tests, with enhanced anti-aging performance
Thermal management performance optimization: The thermal conductivity is as low as 0.043 W/(m·K), providing excellent heat insulation and heat preservation performance
Long-term sealing guarantee: Compression permanent deformation ≤30%, rebound rate over 90%, ensuring the durability of the seal
Safety and environmental protection certification: Achieves UL94 V-0 flame retardant grade, low VOC emission, and complies with the EMARK certification for automotive interiors
The halogen content has been significantly reduced to below 1500ppm, far exceeding the industry's environmental protection standards
It maintains performance stability under operating conditions ranging from -40℃ to 120℃, and its performance remains excellent after thermal aging
The anti-aging performance has been enhanced through ultraviolet aging and ozone aging tests
The thermal conductivity is as low as 0.043 W/(m·K), and it has excellent heat insulation and preservation performance
