Rubber-a material made by chemically treating and toughening this substance, valued for its elasticity, nonconduction of electricity, shock absorption, and resistance to moisture, used in the manufacture of erasers, electrical insulation, elastic bands, crepe soles, toys, water hoses, tires, and many other products.
It is widely used in daily life have a lot of rubber for our services, through wearing by urban and rural residents, it is must be a kind of consumption is very big, with a rubber are in play its role in people's life. In addition, rubber is widely used in cultural and educational institutions, offices, design drawing and sports equipment.so there are many kinds of performance testing rubber material should be tested before application . those testing include as following:
Physical mechanical properties:Density, hardness, surface resistivity, dielectric properties, tensile properties, impact properties, tear properties, compression properties, adhesion strength, wear resistance, low temperature performance, resilience energy.
Aging performance:Heat aging, ozone aging, ultraviolet lamp aging, salt fog aging, xenon lamp aging, carbon arc lamp aging, halogen lamp aging.
Combustion performance:Vertical combustion, alcohol burner combustion, roadway propane combustion, smoke density, combustion rate, effective combustion calorific value, total smoke emission.
Applicable performance:Hydraulic, pulse test, conductive performance, water tightness, air tightness.
Toxic and harmful substances:Soluble heavy metals, phenylplasticizers, formaldehyde, REACH, Rosh, etc.
Physical and chemical index detection:Unvulcanized rubber Mooney viscosity, unvulcanized rubber vulcanization characteristics, unvulcanized rubber plasticity index and recovery value, density, rheological properties, Shao Er hardness, the hardness, raw rubber and plastic retention (PRI), swelling index, permeability, total hydrocarbon content, the content of polyisoprene, the contents of polycyclic aromatic hydrocarbons, black carbon, etc
Mechanical performance detection:Tensile strength and tensile elongation, compression set, fixed and permanent deformation, compression stress relaxation and tensile stress relaxation, tear strength, bending strength, impact strength, shear strength, abrasion test, adhesion strength, resilience, elastic modulus, the coefficient of friction, etc
Thermal performance detection:Glass transition temperature, ash, horizontal combustion, vertical combustion, oxygen index, low temperature brittleness, low temperature rigidity, compression resistance coefficient, tensile resistance, thermal conductivity, crystallization effect, etc.
Electrical performance detection:Resistivity, dielectric constant and dielectric loss Angle tangent value, breakdown voltage strength, etc.
Reliability detection:Artificial climate ageing (fluorescent uv lamps, xenon lamp, carbon arc lamp), resistant to ozone aging test, hot oxygen aging test, liquid resistance, thermal accelerated aging, damp and hot air aging test, salt spray test and acidic salt spray test, gas corrosion test, hydrostatic test, impulse performance, mouldproof performance, etc
