Abstract
Abstract A sheet transport member has at least one surface for movable engagement with a sheet to be transported made from an elastomeric thermoplastic styrene-ethylene-butylene-styrene block copolymer and a polysiloxane substantially uniformly dispersed throughout the copolymer, the polysiloxane being present in an amount of from about 0.5% to 8% by weight of the total weight of the composition and having a viscosity of from about 20 to 1,000,000 centistokes.
