The motor vehicle industry uses a wider range of polypropylene applications than any other industry, all of which exploit the fundamental advantages of polypropylene.

Applications range from bumper covers weighing several kilograms to control knobs weighing a few grams.

Processes include injection moulding, low pressure moulding, blow moulding, thermoforming, profile extrusions, and extruded fibre for automotive carpet.

Grades range from homopolymer through to fully chemically coupled glass reinforced compounds, with many newer applications requiring tailor made properties to optimise performance and minimise cost.

About Grade Selection
The different demands of the engine compartment compared to interior trim, for example, lead to the use of many different PolyPacific compounds.

The purpose of this section is to provide a guide to the matching of specific requirements of individual applications against the properties of different compounds.

For convenience, the applications are grouped under the sub-headings of :

•  Interior Components

•  Exterior Components

•  Engine Compartment
 (including lighting)
