THIOUREA Resistant O-Rings and Seals
Thiourea, also known as thiocarbamide and sulfourea, is an inorganic compound with a wide range of industrial applications. It is commonly used as a raw material for thiourea dioxide, a bleaching agent for paper and textiles, as well as a component of agricultural chemicals, pharmaceuticals and dyes.
When exposed to thiourea, common rubber material types such as neoprene, butyl, EPDM and natural rubber can suffer from swelling and softening. This can lead to an increased risk of leaks, reduced strength and inadequate sealing. Additionally, the chemical can cause embrittlement of the rubber, leading to premature failure. Furthermore, thiourea can cause the rubber to become brittle and crack due to the chemical's corrosive and oxidizing properties.
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.
