Triaryl phosphate, also known as TAP, is a common industrial chemical used in a variety of products and applications. It is used as a flame retardant, a plasticizer, a fuel additive, and in various pesticides and herbicides.
When exposed to triaryl phosphate, rubber materials can suffer from a variety of failure modes. These can include swelling, softening, embrittlement, cracking, and discoloration. Swelling occurs due to plasticizers in the chemical leaching out the plasticizers in the rubber, which can lead to a loss of strength and cracking. Embrittlement can occur as a result of 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.
