Application
In the process of vulcanization, the crosslinking rate of sulfur alkyl is the same as deoxid izing rate of sulfur, so it act to resist deoxidization of vulcanization, and then improve dynamic bending properties such as heat build up and cracks expansion .The four sulfur atoms can act as activator for vulcanization.
In dynamic and static conditions, It is used for producing these rubber products: tire, hose, rubber roll, belting, cable, footwear and mechanical founding products. It can improve abrasive resistance, cutting resistance and pressure resistance, reduce hysteresis loss and hy groscopicity , improve mechanical and adhesive properties, increase thermal ageing performance, modulus and flex life.
