Polypropylene is the lightest of all thermoplastics available today, and like polyethylene, it will float. Other product features are excellent dimensional stability and electrical properties, good surface hardness and chemical resistance, and easy coloration.
The combination of polypropylene’s properties makes it desirable for a broad mix of applications. In many areas where fluoropolymer tubing is typically used, polypropylene tubing can be employed as a relatively low-cost alternative. The high-crystalline composition also makes it good for use in structural systems. Polypropylene (PP) tubing is weldable and, when welded, can be used in non-fluid transfer applications.
