HDPD/HDDD Type Specification
EPDM synthetic rubber vulcanization of the further strengthen of the materials of polymer, the good performance for Aging resistance, weather resistance, electrical insulation, corrosion resistance, impact resistance etc.
Natural rubber has excellent properties of high elastic insulation, waterproof, low specific gravity, after appropriate treatment with alkali, heat, cold, pressure. Full solid be consistent from beginning to end, and has maximum compression deformation. Its advanced partition design maximizes absorption and recovery of energy.
