Semi-Finished Products  PVDF sheet/rod/tube 


Polyvinylidenefluoride (PVDF)

This is a relatively new fluoropolymer and its best feature is chemical resistance. It has notably higher chemical properties than PTFE but is less vulnerable to strain under load.

                                    

Product strengths:

·         Higher chemical properties than PTFE, e.g. tensile and compressive strength

·         Very good thermal resistance at low and high temperatures up to 150°C

·         High UV resistance

·         Excellent dimensional stability

·         Low flammability

·         Low friction coefficient

 

Product weakness:

·         Resistance to high temperatures is lower than PTFE

·         Produces toxic fumes when burned

 

Applications:

Mechanical: Due to low coefficient of friction, it is ideal for bearings, even in water.

Electrical: Very good dielectric properties; halogen free; self-extinguishing and weatherproof. It is increasingly indispensable for electrical applications.

Chemical: Excellent chemical resistance to acids and alkali typical of the fluoropolymers and is particularly suited for petrochemical and chemical industries.

Food contact: It is physiologically inert and approved for food contact by the majority of international standard organizations and widely used for components in food machinery: pumps for liquid food, etc.
