PRODUCT DESCRIPTION
FFKM FLS-8701B is one of the perfluoroelastomers, which is designed for the semiconductor of dry and wet etching process and has the same quality with Kalrez FFKM product. It can be applied to most of chemicals (e.g. hydrochloric acid, nitric acid, hydrofluoric acid.), providing the excellent chemical resistance to acids, bases, and organic solvent. However, we recommend you to avoid amine.
FFKM FLS-8701B offer excellent physical properties and thermal stability (Oxygen free TGA test), please check the following comparison sheet with Kalrez 4079. Under normal condition, the continuous service temperature can exceed 330°C.
