Our quality control program begins with raw materials. We always use 100% virgin and prime polymer and elastomer. It is the only SOP to consistently produce high performance and long lasting ChangRubber rubber sheets. We sourced our raw materials only from approved suppliers with Test Certificates. The followings are some of brands we worked with.
