Oil-bleeding & Low Compression Set LSR

It is a two parts, platinum cured, opaque materials with oil bleeding properties for injection molding process. It is designed to manufacture molded pieces. 


After the curing process, an oil film exudes out of the vulcanizates over an extended period of time. This platinum silicone rubber has a good mechanical property and a low compression set after molded without post-curing.
