Polypropylene®

PROTEC is a high corrosion resistant Polypropylene material that has high temperature and tensile strength. Polypropylene possesses excellent resistance to organic solvents and degreasing agents as well as electrolytic attack.

Compared to low or high density polyethylene, Protec has a lower impact strength but superior working temperatures and tensile strength. In addition, Protec is lightweight, stain resistant and has a low moisture absorption rate.

Fabrication Characteristics - top

Thermoplastic preparation for assembly (welding or other fastening methods) is similar to metal fabrication procedures. Pieces are laid out, cut, machined and joined with the same tools, equipment and skills utilized in the metalworking trades. However, there are special forming requirements for thermoplastics not encountered in metal work.

Fabrication of thermoplastics includes a wide range of operations on sheet, rod, tube and special shapes to produce finished products. Fabrication involves cutting, sawing, machining, forming, joining or fastening together for the completed object. Machining may include beveling, routing, grinding, turning, milling, drilling, tapping and threading.

The degree of skill and the quality of preparatory work in layout and various machining operations on components for fit-up are very important in assuring accurate assembly and successful fabrication.

Once the different thermoplastic parts are formed into the proper shape, they may then have to be joined. The type and method of assembly depend on the function of the finished structure. The several assembly techniques include the use of adhesive bonding, self-tapping screws, threaded insets, press fitting, cold heading, heat joined (hot- plate welding, hot-wire welding, induction heating, hot flaring, and spin welding) cementing and hot gas welding. Each operation requires its own tools and equipment.
