RUBBER LUBRICANT COMPOSITION

摘要

POLYMER COMPOSITION The instant invention relates to a rubber lubricant composition characterized by complete wetting of the elastomer surface both before and after vulcanization which gives a matte finish on cooling down that remains soft and does not flake off. This comprises (1) polyoxypropylenepolyoxyethylene block copolymer having a molecular weight of the polyoxypropylene hydrophobe of about 2500 to 4000 and containing 20 to 80 percent oxyethylene groups and (2) an oxyethylated oxypropylated higher alcohol.
