What is thermoplastic PVC?  First let's discuss thermoplastics and then specific details about PVC.

Thermoplastics

Geist Plastics' President, Dominic Pynes, was recently interviewed by Jerry Hoffman for the Hoffman Strategy Group's blog.

Here is an excerpt from their blog:

Call it the supply chain, call it the extended enterprise. At Geist Plastics, we refer to the role our suppliers play in assisting with the manufacturing and sale of plastic extrusion as integral to our customers’ success.

All business owners and managers say, "We greatly value our customers. Without them we wouldn't be in business."

But we all know companies who fall short – be it in attitude, professionalism, product quality, customer relations, or delivery. When it happens once, or on occasion, a customer may overlook it.

We have customers who treat us like a partner.

Several years ago while I was division president of Apex Plastics, our blow molding manufacturing division, we wrestled with a production problem for a few weeks. We had a fairly new technician who struggled with unacceptable variations in the wall thickness of a bottle. After close examination, we discovered that he was not maintaining a consistent percentage of regrind.

Plastic products take many different forms - known as plastic profiles to us - but they all start as raw material called resin. In plastic extrusion, resin beads are melted down, filtered for uniform consistency, pushed through a die cut for the final product shape, and then cooled. It's a complicated process that takes many forms, but here's a quick breakdown of how it works.

1. Raw plastic is fed into a hopper - along with any colorants or additives - that feeds down into the extruder.
