Note: ○—— Longer life, △—— General life, ×—— Not available. This table is only from corrosion resistance. Due to the elasticity of poly four vinyl chloride is worse than that of rubber, so the actual service life is different due to pressure, pump stroke impurities and other factors. Food and beverage rubber is used in food and beverage industry.
