TRIALLYL PHOSPHATE Resistant O-Rings and Seals

Triallyl phosphate, also known as TAP, is a common industrial chemical used in a variety of products and applications. It is used as an antioxidant and flame retardant in plastics and rubber, as a lubricant, and in adhesives. It is also used as a plasticizer, as a fuel additive, and in various pesticides and herbicides.

When exposed to triallyl phosphate, rubber materials can suffer from a variety of failure modes. These can include swelling, softening, embrittlement, cracking, and discoloration. Swelling is the most common failure mode, and it typically occurs due to plasticizers in the chemical leaching out the plasticizers in the rubber. Softening can also occur, which can lead to cracks in the rubber due to the loss of strength. Embrittlement can occur due to the chemical breaking down the polymers in the rubber, leading to a loss of elasticity. Cracking can occur due to the chemical reacting with the rubber and causing it to become brittle. Finally, discoloration can occur due to the chemical reacting with the rubber’s pigments.
