DIGLYCOL CHLOROFORMATE Resistant O-Rings and Seals

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.
