Besides its resistance to thermal aggression, KAFLON® is chemically inert towards practically all substances.
Its unique properties make it the ideal choice for both extreme cases or critical applications

KAFLON®, like other perfluoroelastomers, is based on a perfluorated tetrafluoroethylene copolymer that includes the chemical resistance of PTFE and the softness and elasticity of rubber. KAFLON® has shown resistance performances equal, if not superior to the best perfluoroelastomers known to date. It actually possesses unique properties of elasticity, deformability and compatibility to both inert and chemically aggressive substances.
