SILICONE RUBBER COMPOSITION FOR PAPER-FEEDING ROLL AND PAPER-FEEDING ROLL

摘要

PROBLEM TO BE SOLVED: To provide a paper-feeding roll having high friction coefficient and excellent abrasion resistance and causing little lowering of the friction coefficient after the use for a long period. SOLUTION: The silicone rubber composition contains 100 pts.wt. of a silicone rubber, 8-50 pts.wt. of carbon black and 1-10 pts.wt. of an amino-modified silicone oil. The carbon black has a specific surface area of 70-300 m2/g measured by nitrogen-adsorption.
