Abstract
An improved processable silicone rubber composition composed of a blend of 1 to 10 percent by weight of vulcanized particulate silicone rubber and 99 to 90 percent by weight of unvulcanized or virgin silicone rubber that can be tubed at a faster rate and lower temperature to minimize structure formation.
Claims2
An improved processing silicone rubber composition composed of 1 to 10 weight percent of vulcanized powdery particulated silicone rubber having an average particle size of less than 20 microns and 99 to 90 weight percent of unvulcanized silicone rubber.
A method of tubing silicone rubber comprising mixing 1 to 10 weight percent of unvulcanized powdery particulate silicone rubber having an average particle size of less than 20 microns with 99 to 90 weight percent of unvulcanized silicone rubber to obtain a blend and then extruding said blend to form a tube.
