    Abstract: When a small amount of polytetrafluoroethylene powder is mixed with certain curable polydiorganosiloxane compositions containing a reinforcing silica and an organic peroxide curing agent and the resulting mixture is extruded and heat-cured, the resulting elastomeric article has a durometer of less than 30 and has a greatly reduced amount of porosity or bubbles.

    Abstract translation: 当将少量的聚四氟乙烯粉末与含有增强二氧化硅和有机过氧化物固化剂的某些可固化聚二有机硅氧烷组合物混合并将所得混合物挤出并热固化时,所得弹性体制品的硬度小于30,具有很大的 减少孔隙率或气泡量。
