Cellulose acetate butyrate, also known as CAB, is a thermoplastic used in a variety of industries. It is often used in the manufacture of films, fibers and plastics that require strength and stiffness. Common applications include eyeglass frames, automotive components, and plastic bottles.
When rubber is exposed to CAB, it can cause a variety of failures. The material can cause swelling of the rubber, resulting in a decrease in mechanical strength and an increase in permeability. In some cases, the rubber can become brittle and crack due to the plasticizer migration. In addition, the material can cause discoloration of the rubber due to UV exposure.
Fluorosilicone o-rings are a hybrid of silicone and FKM resulting in great jet fuel resistance with high and low temperature performance. Also widely used in semiconductor Ashing equipment with strong resistance to oxygen plasma, FVMQ fluorosilicone o-rings also feature excellent flexibility, compression resistance, aging and sunlight resistance, and overall wide range of basic chemical resistance.
