Generally, rubber performance testing can be conducted in accordance with ISO, ASTM, DIN, GB, HB and other standards to test the physical, chemical, and mechanical properties of raw rubber, vulcanized rubber, rubber products, and rubber additives. 1、 Performance indicators: Physical and mechanical properties: density, hardness, surface resistivity, dielectric properties, tensile properties, impact properties, tear properties, compression properties, adhesive strength, wear resistance, low temperature performance, rebound performance, aging performance: thermal aging, ozone aging, UV lamp aging, salt spray aging, xenon lamp aging, carbon arc lamp aging, halogen lamp aging, liquid resistance: lubricating oil Gasoline, engine oil, acid, alkali, organic solvents, water resistant combustion performance: vertical combustion, alcohol burner combustion, tunnel propane combustion, smoke density, combustion rate, effective combustion heat value, total smoke release. Applicable performance: hydraulic pressure resistance, pulse test, conductivity, water tightness, airtightness related applications: tires, fenders, shoe soles, waterstops, sealing rings, conveyor belts, rubber hoses, cables and wires Automotive interior, building materials, fast moving consumer goods rubber rollers, rubber sheets, medical and health rubber products, rubber pressure reducing products, rubber shock absorbing products, etc. 2. Common rubber testing items: 1. Rubber type evaluation: volatile matter, ash content, tensile strength, constant elongation strength. 2. Production parameters: Mooney viscosity, thermal stability, shear stability, vulcanization curve, Mooney scorch time related application products: natural rubber Silicone rubber, styrene butadiene rubber, nitrile rubber, ethylene propylene rubber, polyurethane rubber, butyl rubber, fluorine rubber, cis-1,4-polybutadiene rubber, chloroprene rubber, isoprene rubber, polysulfide rubber, chlorosulfonated polyethylene rubber, polyacrylate rubber, and other rubbers. 3. Performance requirements for rubber: The performance of rubber can be divided into two categories, including structural performance and functional characteristics. Structural performance refers to mechanical properties such as high elasticity and strength; Functional characteristics refer to the physical and chemical properties of rubber, such as dielectric resistance, electrical insulation, chemical corrosion resistance, etc. In rubber products, some mainly utilize the former type of performance, such as shock absorption products, sealing products, etc; Some mainly utilize the latter type of performance, such as water sealing (water resistance) and cable sheath (electrical insulation). But among all the properties, structural performance and mechanical performance are the most important. Because it is the foundation of all performance
