Echo Perfluor

Echo Perfluor is AIR WATER MACH’s proprietary ultra-high performance fluororubber. It maintains the properties of conventional fluororubbers and can be used under severe conditions impossible with conventional rubber including organic polar solvents, various chemicals (*), acids, and alkalis. This revolutionary special synthetic rubber can be used in ways like fluororesin (Teflon).

* Amines, anilines, ketones, esters, ethers, furans, aromatic hydrocarbons, aliphatics, and other chemicals

Echo Perfluor is a special synthetic rubber that features a wide operating temperature range and the best steam resistance among synthetic rubbers. It can therefore be used in places where seal material should be used, but in practice, fluororesin and metal packings are the only materials that can be used. Compared to other rubbers, Echo Perfluor exhibits less outgassing and it is also suitable as a sealing material for manufacturing equipment such as that for semiconductors. Echo Perfluor is consistently processed in a clean room starting from mixing and molding all the way to cleaning and packaging.

Features

Exceptional chemical resistance, solvent resistance, and oil resistance

Solvent Resistance and Chemical Resistance of Echo Perfluor

Among fluororubbers, Echo Perfluor demonstrates outstanding solvent resistance and chemical resistance. It can be used under severe operating conditions and in applications not possible with conventional fluororubbers. Unlike vinylidene fluoride rubbers, Echo Perfluor can also be used with ketones, esters, furans, organic acids, alkalies, and amines. However, in Freon solvents, its volume increases greatly due to its similar scientific composition.
