Ozone Resistance Environmental Testing Chamber Environmental Tester Ozone Accelerate Aging Testing Chamber
1. Product application:
The tester is used for the ozone-resistance test of the rubber and rubber products
2. Test principle:
The ozone aging test chamber is applicable to the rubber products like vulcanized rubber and thermoplastic rubber, cable insulation sheath, etc. Exposed to the closed dark environment with constant ozone concentration and temperature, the sample is stretched statically or dynamically or alternately. After the preset testing time, check the rubber or rubber products for any fracture or other changes. Then evaluate the ozone-resistance performance of the sample and take effective measures to increase the sample lifetime.
Static tensile test:
Fix the sample in the special fixture, and then choose one elongation rate for the sample (generally 20%). The fixture is installed on the rotational sample shelf with the speed of (20~25)mm/s. The test temperature is(40±2)℃ and the relative humidity is less than 65%.
