PVDF

KYNAR® PVDF (Polyvinylidene Fluoride)

This fluoropolymer material has superior chemical and abrasion resistance, mechanical strength and temperature capabilities in comparison to all other thermoplastic materials. It offers substantially greater strength and wear resistance over other common fluoroplastics (PTFE, PFA, etc.). It is chemically resistant to most strong acids, mild alkalies, organic solvents, wet or dry chlorines, bromine and other halogens and is also used extensively in the conveyance of high purity deionized water due to its absence of colorants or additives. Because of its outstanding mechanical properties and that it is similarly impervious and non-leaching, PVDF is sometimes used for certain parts in polypro and PTFE valves for design strength. You should check the specifications, or consult factory if this is a concern.

The maximum service temperature is 280°F (138°C); melting point is 170°C.

Kynar PVDF is joined by heat fusion, threading or flanging.
