Food-grade EPDM rubber ring self-lubricating seal, imported raw rubber production butyl rubber.

What is the softness and hardness range of butyl rubber rings? The relationship between elasticity and density: EPDM Shore hardness 30, 35, 40, 45, 50, 55, 60, 65, 70, 75, 80, 85, 90, 59, 95A. A smaller value indicates lower hardness, representing good elasticity and low pressure resistance. A larger value indicates higher hardness, with a stiff elastic feel and high-pressure sealing resistance. Meanwhile, corrosion resistance has little to no relation with softness and hardness! Material performance is related to the formulation and the precision of material composition, such as calcium carbonate. Achieving the target mesh size, precise mixing, mesh filtration, and thorough compounding require standardized operations—SOIP.
