What is Polypropylene or PP?
Polypropylene (PP) is a linear hydrocarbon polymer, expressed as CnH2n. PP, like polyethylene (see HDPE, L/LLDPE) and polybutene (PB), is a polyolefin or saturated polymer.

Polypropylene is one of those most versatile polymers available with applications, both as a plastic and as a fiber, in virtually all of the plastics end-use markets.

Automotive use
In the automotive sector PP is utilized as a monomaterial solution for automotive interiors. The monomaterial dashboard is becoming increasingly achievable, PP film cushioning, film skins, and powder slush molding and even blow molded parts with integral PP textile covers are emerging.

Bumpers, cladding, and exterior trim are also available manufactured from polypropylene. Polypropylene developed for such applications provides low coefficient of linear thermal expansion and specific gravity, high chemical resistance and good weatherability, processability and impact/stiffness balance. Improvements with color-at-the-press and pre-colored PP have also reduced or eliminated the need for painting in some applications.

PP does not present stress-cracking problems and offers excellent electrical and chemical resistance at higher temperatures.

Benefits:

• Improved Aggressive Look

• Aerodynamic Improvements
