Diglycol chloroformate, also known as DGC or chloroformic acid diglycol ester, is a versatile chemical used in a variety of industries, such as medical device manufacturing, pharmaceuticals and agriculture. Common uses for DGC include a reagent for the synthesis of resins and polymers, as an intermediate in organic synthesis, and as an intermediate in the synthesis of pharmaceuticals.
When rubber is exposed to diglycol chloroformate it can cause swelling, hardening and embrittlement of the rubber material. This can lead to a decrease in elasticity, tear strength and tensile strength, making the rubber more brittle and susceptible to cracking or breaking due to external forces, such as bending and twisting. Furthermore, DGC can cause chemical degradation of rubber material, leading to further weakening of the material. Additionally, high temperatures can accelerate the effects, leading to further embrittlement and cracking.
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.
