METHYL ETHYL KETONE PEROXIDE Resistant O-Rings and Seals
Methyl ethyl ketone peroxide (MEKP) is an organic peroxide compound with the molecular formula C5H10O2. It is a colorless, crystalline solid with a pungent odor and is used as an initiator in the polymerization of acrylics and unsaturated polyesters. MEKP is also used in some industrial processes, such as the manufacture of rubber and plastics, as a bleaching agent, and as a fuel additive.
When rubber is exposed to MEKP, the most common types of failure are discoloration, hardening, and cracking. Discoloration may occur due to oxidation and can result in a change in the material’s color, which can affect its overall appearance. Hardening occurs due to the reaction between the MEKP and the rubber, which can make the material more brittle and prone to cracking. Cracking can occur due to embrittlement, which is caused by the chemical reaction with the MEKP.
