Higher build Kynar PVDF and ETFE coatings are replacing FRP and rubber linings on mixers and agitators. Ultimately the extended life span makes them the economical choice for slurries and corrosives over rubber and elastomeric linings.
Kynar PVDF can be filled with abrasion resistant materials to improve its wear properties. Note the thickness on the leading edge is well over 200 hundred mils.
