Polypropylene Welding

Polypropylene is one of the most popular thermoplastics to weld because it has excellent chemical resistance, low specific gravity and high tensile strength. For over 40 years, Miller Weldmaster has manufactured proven solutions for polypropylene welding. Our hot air and hot wedge welding machines are commonly used to successfully weld this material.

What is polypropylene?

Polypropylene is a thermoplastic polymer known for its high melting point. An extremely versatile plastic, polypropylene can be manufactured to be flexible or rigid, and is used to create a number of both commercial and industrial products.
