FVMQ O-rings are widely used elastomer seals that can meet a wide range of applications. The mechanical and physical properties are very similar to silicone rubber.This material is widely used in semiconductor Ashing equipment for its resistance to oxygen plasma.
Due to relatively low tear strength, high friction and limited abrasion resistance of these materials, they are generally recommended for static applications only. Fluorosilicones with high tear strength are also available. Some of these compounds exhibit improved resistance to compression set. Many fluorosilicone compounds have a higher than normal shrinkage rate so production molds for fluorosilicone products are often different from molds for nitrile.
