Dihydroxydiphenylsulfone (DHS) has a few common names, including Dihydroxydiphenylsulfone, DHPS, and Sulfone. It is most commonly used as a polymer additive and modifier in various industries, such as the automotive, electrical, and pharmaceutical industries. DHS is used to improve the heat resistance, flexibility, and antistatic properties of a variety of substances.
When rubber is exposed to DHS, it can cause a variety of failures, such as cracking, brittleness, and discoloration. Furthermore, DHS can cause rubber to become sticky and swell, leading to leakage and other problems. DHS can also cause rubber to become brittle and dry out, leading to cracking and other issues. In general, it is best to keep rubber away from DHS and other chemicals as much as possible.
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.
