Homopolymer polypropylene sheet
polypropylene is a thermoplastic made by the polymerization of propylene gas, a by-product of petroleum refining. Various techniques can alter the physical, chemical or mechanical properties of polypropylene.
Changes in the way the material is polymerized can show dramatic improvements in certain mechanical properties; example, random copolymers block copolymers.
Copolymerization of an additional resin group can enhance physical properties. Addition of fillers can improve mechanical or thermal stability.
Homopolymer polypropylene is a light density (.91-.92 gm/cm3) thermoplastic. It can be stabilized to enhance prolonged use at elevated temperatures, prolonged life in exposure to ultra-violet light and improved flame retardancy.
Polypropylene fabricates with standard woodworking tooling. It can be butt welded, extrusion welded, fusion welded, and spun welded. It can be machined with ordinary wood or metalworking equipment.
