Major tests

• - Mechanical tests regarding rubber materials and components (immersion test, aging test, ozone crack test, etc.)
• - Low temperature characteristic test of rubber materials (Low temperature recovery test, low temperature stiffness test and low temperature brittle test)
• - Durability assessment(fatigue, heat, light field, etc.) and test
• - Bridge bearing performance test for elastic bearing and expansion joint. Field trip test.
• - Mechanical test and performance test of railway parts(elastic pad, dustproof pad and rail fastening device)
• - Test for rubber products such as elastic packaging materials, rubber foam insulation, tires, etc.
• - Assesses the environmental resistance(heat aging, ozone aging, constant temperature and humidity, thermal shock) of rubber and plastic products
