  Whitening of rubber seals is also called frosting in academic terms. After the rubber product is vulcanized and molded, it is often left standing for a period of time, and the surface is like covered with white dust. But in fact, it is the release of rubber compounding agent that forms frosting. For the whitening phenomenon of rubber products, rubber can be divided into unvulcanized rubber (hereinafter referred to as rubber compound) and vulcanized rubber (hereinafter referred to as product), and rubber frosting includes
