Rubber testing generally test what project indicators

Rubber (Rubber), is a highly elastic polymer material with reversible deformation. Rubber is elastic at room temperature, can produce large deformation under the action of a small external force, and can be restored to its original state after removing the external force. Rubber industry is one of the important basic industries of the national economy, it not only provides people with daily life indispensable daily use, medical and other light rubber products, and to the extraction, transportation, construction, machinery, electronics and other heavy industry and emerging industries to provide a variety of rubber production equipment or rubber parts.

One, the concept of rubber performance testing

General rubber performance testing can be done in accordance with ISO, ASTM, DIN, GB, HB and other standards, to carry out the rubber rubber, vulcanized rubber, rubber products, as well as rubber auxiliaries with the physical and chemical properties of the agent, mechanical properties and other tests.

Second, rubber performance index items:

Physical and mechanical properties: density, hardness, surface resistivity, dielectric properties, tensile properties, impact properties, tearing properties, compression properties, bonding strength Abrasion resistance, low temperature performance, resilience

Aging properties: heat aging, ozone aging, UV aging, salt spray aging, xenon lamp aging, carbon arc lamp aging, Halogen lamp aging

Liquid resistance: lubricating oil, gasoline, oil, acid, alkali, organic solvents, water resistance

Burning performance: vertical combustion, alcohol blowtorch combustion, alley propane combustion, smoke density, burning rate, effective calorific value of combustion, total smoke release

Applicable performance: hydraulic pressure resistance, impulse test, electrical conductivity, water-tightness, air-tightness

Related applications:

Tires, fenders, shoe soles, water stops, seals, conveyor belts, rubber hoses, cables and wires, automotive interiors, construction materials, fast consumer rubber rolls, rubber sheets, medical and health care rubber products, rubber pressure-relief products, rubber shock-absorbing products, etc.

Three, common rubber test items:

1, the rubber species evaluation: volatile matter, ash, tensile strength, fixed elongation strength, and the amount of smoke release, the amount of smoke release. Tensile Strength, Constant Elongation Strength

2, Production Parameters: Menni Viscosity, Thermal Stability, Shear Stability, Vulcanization Curve, Menni Scorch Time

Related Applications:

Natural Rubber, Silicone Rubber, Styrene-Butadiene Rubber, Nitrile Butadiene Rubber, Ethylene-Propylene Rubber, Urethane Rubber, Butyl Rubber, Fluorine Rubber, Sunbutadiene Rubber, Chloroprene Rubber, Isovalerine Rubber, Polymerized Vinyl Rubber, Polysulfide Rubber Chlorosulfonated polyethylene rubber, polyacrylate rubber, other rubbers.

3, rubber performance requirements:

Rubber performance can be divided into two categories, and structural properties and functional properties, structural properties refers to high elasticity and strength and other mechanical properties;

Functional properties refers to the physical and chemical properties of rubber, such as media resistance, electrical insulation, chemical corrosion resistance.

In rubber products, some of them mainly utilize the former type of performance, such as shock-absorbing products, sealing products, etc.; some of them mainly utilize the latter type of performance, such as water seals (water resistance) and cable sheaths (electrical insulation), etc.. But in all the properties, structural properties and mechanical properties are the most important. Because it is the basis of all performance.
