摘要：
A composition which possesses both good lubrication and release properties for use in the manufacture of molded rubber articles composed of a mixture of(a) monoalkyl ethers of oxyethylene-oxypropylene copolymers, in which the weight ratio of oxyethylene groups to oxypropylene groups is 25 to 75:75 to 25; and(b) polyoxyalkylene-polysiloxane copolymers in which the components (a) are soluble or dispersible.
