Perfluoroether elastomer,with trade name of SHIN-ETSU SlFEL~R,is based on a perfluoroether polymer backbone combined with silicone functionality for crosslinking.This material family is available with many different appearances from low viscosity flowing liquid to gum solid,along with intermediate types of viscous fluid and paste.Upon curing,SlFEL family offers a variety of elastomeric products such as molded rubber parts,low modulus adhesives,soft coating layers,and very soft and sticky gels.This wide variation of products is a result of combined technical achievements of chemical composition,filler loading and rubber formulation.Thanks to excellent characteristics of perfluoroether polymer,SlFEL products have outstanding properties of low temperature flexibility,heat resistance,and improved resistance to fuels,solvents,acids,and alkalis compared to standard fluoroelastomers.The introduction of SlFEL provides oilfield engineers with a wide range of opportunities to improve the performance of sealing,coating and bonding operations in various applications exposed to severe conditions.
