Title: RUBBER COMPOSITION FOR PAPER FEEDING ROLL AND PAPER FEEDING ROLL
Abstract:
A rubber composition comprises at least a polymer component, a softening agent, and a crosslinking agent. The polymer component occupies 44 mass% or more of the rubber composition for a paper feeding roll, the polymer component including an ethylene-propylene-diene copolymer. The softening agent is at least one of a poly-α-olefin and a long-chain alkyl carbonate having a kinematic viscosity at 40°C of 10 mm2/s to 60 mm2/s. What is thereby provided is a rubber composition for a paper feeding roll and a paper feeding roll having exceptional friction coefficient retention and wear resistance.
