NOVELTY - High clean rubber composition comprises 50-100 pts. wt. silicon rubber, 20- 60 pts. wt. fluorine rubber, 10-20 pts. wt. cellulose, 10-20 pts. wt. graphene, 5-10 pts. wt. calcium carbonate, 5-10 pts. wt. Suzhou soil, 15-20 pts. wt. silicon micro powder, 1-5 pts. wt. vulcanizing agent, 3-15 pts. wt. silane coupling agent, 10-20 pts. wt. antioxidant and 10-20 pts. wt. reinforcing agent. USE - Used as high clean rubber composition. ADVANTAGE - The high clean rubber composition is hard, is resistance to high and low temperature and aging resistance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing high clean rubber composition comprising taking silicon rubber and fluorine rubber into an open mill, (b) mixing silicon rubber, fluorine rubber, calcium carbonate, Suzhou soil, cellulose, silicon, micro powder, antioxidant, reinforcing agent, vulcanizing agent, silane coupling agent, mixing twice, (c) stopping after 15 hours, (d) carrying out second stage curing process, curing first stage at 1150 degrees C, vulcanizing for 20 minutes, curing second stage at 160 degrees C and vulcanizing for 6 hours.
