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

INSTALLATION NOTE: 

Many Carbon Fiber, PP, and ABS aftermarket products are engineered to be exact replicas of OEM products. These products should always be test fitted prior to PREP, PAINT, or INSTALLATION.  In some cases - largely dependent on the car and installer experience, slight modifications may be required such as trimming, sanding, filing, or smoothing the surface in order to get best fitment and appearance. 1000s of people have installed these products, so it's best to find a qualified installer who has experience. Sometimes aftermarket products will not be perfect fit out of the box.  Standard insurance company body shops, installers, or people with limited experience may make the installation process more difficult than it needs to be and provide the wrong impression of the product. Always seek an installer experienced in aftermarket product installations. 

All images are provided as a true representation of the fit and finish of our products, while this disclaimer is necessary, the reality is that 99.99% of the time, there are limited or non-existent issues with properly installed aftermarket body kits that Umnitza sells. All products sold on this site have been vetted and installed by Umnitza at our own facility and at our body shops in our own area and others.
