Abstract
A silicone molding composition with improved thermal shock resistance having a plasticizing amount of a silicone resin comprising chemically combined RSiO.sub.3/2 units and R.sub.2 SiO units where the R to Si ratio may vary from 1.0 to 1.9 and the ratio of RSiO.sub.3/2 units to R.sub.2 SiO units may vary from 1:2.5 to 1:5.0 and containing less than 0.5 weight percent of silanol groups and preferably being substantially free of silanol groups where R is a monovalent hydrocarbon radical. There is also provided by the present invention a process for improving the thermal shock resistance of a silicone molding composition by having in said composition the aforesaid resin.
