The combination of polypropyleneâs 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.he combination of polypropyleneâs properties makes it desirable for a broad mix of applications.
