BORIC OXIDE Resistant O-Rings and Seals
Boric oxide, also known as boric anhydride and boron trioxide, is a white crystalline chemical compound. Common uses for this chemical include its use as a flame retardant, in the production of enamels, as a flux in metallurgy, and in catalysts.
When rubber is exposed to boric oxide, it can cause cracking and stiffening, as well as discoloration and premature wear. Additionally, long term exposure to boric oxide can cause swelling and decreased tensile strength, leading to the rubber breaking down more quickly than normal.
Fluorosilicone (FVMQ, FSIL)
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.
