PTFE (TFE) and PVDF are both on allocation.
PTFE - Polytetrafluoroethylene products, PTFE (TFE) along with Kynar-PVDF manufacturing requires a mineral called Fluorspar that is mined in Mongolia and China. The worldwide demand for this mineral has grown significantly, additionally, the supply has tightened. PTFE materials have high temperature resistance, excellent chemical resistance and extremely low co-efficient of friction (slick) and is utilized in a good deal of purposes from non-stick fry griddles to ptfe tape for personal use. This specific mineral is actually the critical raw materials in the manufacturing of fluoropolymers, fluorolubricants and several refrigerants.This increased demand mixed with shortage of raw materials has caused a dramatic price increase (almost double over the past year), shortages, and we expect these two factors to continue in the near future.
