- PVC and Nylon Powder
Materials that Piper can process...
Piper Plastics Corp. specializes in processing thermoplastics, mostly PVC and Nylon.
A thermoplastic is a plastic that fuses, (cures, or sets) by the application of heat and not because of a chemical reaction as is the case with thermoset plastics. What this means is that as the temperature of a thermoplastic part rises, the part becomes more flexible. In theory, it should be possible to re-mold a thermoplastic part into something completely new, but in practice this isn't really the case. Most often, dip molded thermoplastic parts are chopped up into tiny little pieces and then recycled into other thermoplastic manufacturing processes like extrusion, injection molding, and calendering.
PVC is also know as polyvinyl chloride, and more commonly... vinyl. Piper processes PVC in two forms, as a liquid in our dipping process known as plastisol, and a vinyl powder used in our fluidized bed processes.
The nylon we process is also a powder, and we use it in our fluidized bed process.
(Finally, Piper process a small amount of silicone rubber to make retention cuffs for medical devices that can be directly glued to PVC components.)
