Peracetic Acid, also known as Peroxyacetic Acid, is a strong organic acid typically used in concentrations of less than 10% for sterilization and disinfection of surfaces and equipment. It is also used for bleaching, deodorizing, and oxidation in the food, pharmaceutical, and water treatment industries.
When rubber is exposed to peracetic acid, even in low concentrations, it can cause the rubber to become brittle and crack. This can lead to weakened seals, which can fail to hold pressure and cause leaks. Additionally, the acid can cause corrosion and degradation of the rubber. This can lead to decreased elasticity and flexibility, making the rubber more prone to cracking and abrasion. Prolonged exposure to peracetic acid can cause irreversible damage, making it important to ensure rubber components are adequately protected.
Markez ® high performance perfluoroelastomer O-Rings (FFKM) offer unmatched value for demanding sealing applications. Produced from nearly identical ingredients as higher priced brands, Markez ® compounds are used for high temperature o-rings and high pressure o-rings and chemical resistant o-rings that deliver similar performance to major FFKM brands, with temperature resistance up to 625oF, at a significantly lower cost. Our proprietary processing allow us to supply seals under an inch in size more efficiently. Introduced exclusively to existing customers over 15 years ago, we now have the experience and capacity to offer Markez ® high temperature o-rings and high pressure o-rings to the world.
