What Are Thermoplastics?

Thermoplastics are plastic materials that become pliable or moldable when heated above a specific temperature and harden upon cooling.
 

What is Thermoplastic Welding?

Thermoplastic welding is a process used for joining pieces of thermoplastic material using heating, pressure and cooling. To begin the weld, the surface of the thermoplastic material is heated to its melting point, or thermoplastic state. Each material has its own thermoplastic state, which usually ranges between 250°C (480°F) and 500°C (1022°F).

The material is then pressed together until it cools. The pressure applied allows molecules in the material to newly position themselves, or to bond with molecules of another part.

Several methods of welding have been developed for thermoplastics. Hot air plastic welding is generally used on thermoplastic materials that have a thickness of 1/16 of an inch or more. Click here to learn more about Miller Weldmaster’s hot air welders perfect for welding PVC plastic.

 

Why do manufacturers choose thermoplastic for welding?

Thermoplastic welding has several benefits for manufacturing industries:

  • Light weight
  • High strength
  • Design flexibility
  • Low processing costs
  • Better fatigue properties than metals

 

What are the most commonly welded thermoplastics?

The most commonly welded thermoplastic materials are:

Polypropylene (PP)

Industries such as ducting and packaging use polypropylene coated fabrics for a variety of applications.

Polyethylene (PE)

Agriculture and geomembrane industries have been welding polyethylene for years, but the sign industry has started to adopt this type of welding as well.

Polyvinylchloride (PVC)

The awning, sign, banner, tent and ducting industries commonly use PVC laminated fabric.

If you’re looking for an industrial fabric or thermoplastic welder, Miller Weldmaster can help.
