Chemical media resistance test of automotive plastic products

The temperature resistance test of automotive plastic products can measure the changes that occur when the products are immersed in or come into contact with fuels, oils, greases, drugs or solvents commonly used in automobiles. Zhongke Testing Reliability Experiment Center has the capability of reliability testing of various plastics and provides professional temperature resistance testing services for automotive plastic products.

1. Polycarbonate plastic: lamps, instrument signs, sun visors, window glass, bumpers, etc.;
2. RIM plastic: bumpers, radiator grilles, spoilers, fenders, etc.;
3. Polyethylene plastic: damping materials for fenders, ceilings and doors, trunk mats, air ducts, gasoline tanks, etc.;
4. Polyvinyl chloride plastic: instrument panel cover, car roof lining, rear cover skin, spare tire cover, steering wheel, bumper cover, wire coating, etc.;
5. Polypropylene plastic: heating and ventilation systems, cabins, engine compartments, car bodies, light housings, tool boxes, wire terminals, junction box covers, silencers, etc.;
6. ABS plastic: rear fenders, instrument panels, radio covers, air exhaust pipes, steering wheel horn covers, grilles, rear guards, upper ventilation covers, wheel covers, blinds, brackets, mirror frames, etc.;

According to the adhesion of chemical media on products, the test classification is as follows:
a) Dip test: immersion test at room temperature, immersion test at high temperature
b) Wiping test: Wiping test at room temperature, Wiping test at high temperature
c) Drop test: room temperature drop test, high temperature drop test
