We have a 126 members product R & D and technical management team, and established six rubber laboratories, including material test, formula test, compound test and finished product test. Flame retardant laboratory has alcohol blowtorch, propane blowtorch, oxygen index, roller friction, static electricity and other testing methods, which can comprehensively analyze the safety and fire resistant performance of products; Vulcanization instrument, scorch test machine, electron microscope, ozone instrument and other testing instruments can test the comprehensive performance of the compound, and help technicians quickly find solutions to the performance defects.
