PVF is dispersed in a solvent for melt extruding2.
Fluoropolymers have high melting points and corresponding high processing temperatures and continuous use temperatures, depending on the specific product.
Perfluoroalkoxy (PFA), for example, is at the high end; it has a typical continuous use temperature of 500°F (260°C) and typically reaches 715°F (380°C) during processing; equipment temperatures can be even higher than the melt temperature3.

Injection Molding Parameters These recommendations are regarded as a general starting point.
Hot Melt Hot melt adhesives are 100% solids, and are used for light duty applications.
This rotating is what helps melt and mix the material making it a homogeneous melt.
