Triglycol is also known as 1,2-propanediol, methylethylene glycol or methyl glycol. It is commonly used as a solvent or a plasticizer in the production of plastics and rubber. It is also used as an intermediate in the production of polyester fibers, antifreeze and pharmaceuticals.
When rubber is exposed to triglycol it can suffer from reduced tensile strength, decreased elongation and embrittlement. The rubber material can also become brittle and less flexible over time. The chemical can also cause the rubber to swell and crack, leading to premature failure of the seal. The degradation of the rubber can be accelerated when the chemical is exposed to higher temperatures or UV light.
Viton ® o-rings from Marco Rubber offer excellent compatibility with a range of chemicals, oils and resist high temperatures up to 400F. Viton ® is also known as FKM made of fluoroelastomer one of the most versatile and widely used sealing materials.
