POLYMERS USED

Preferred Polymer Groups in Automotive

In automotive applications, the part’s location, mechanical load and aesthetic requirements determine material selection.

PP Copolymer

It is one of the most widely used polymers in automotive because of its high impact strength at low temperatures.

  • Bumper and exterior trim parts
  • Interior trim panels
  • Engine compartment parts

PE

Preferred in applications such as fuel and fluid reservoirs thanks to its chemical resistance and light weight.

  • Fuel tank
  • Fluid storage reservoirs
  • Protective coatings
Explore PE Grades →

Flexible PVC

Used in cable and gasket applications thanks to its flexibility and flame-retardant properties.

  • Wiring harness insulation
  • Door and window gaskets
  • Floor coverings

SELECTION CRITERIA

Factors That Influence Polymer Selection in Automotive

The right material should be chosen according to the part’s location, temperature exposure and aesthetic requirements.

01

Light Weight

Reducing vehicle weight is a critical design goal for fuel efficiency.

02

Impact Strength

High impact strength is required, especially on exterior parts, even at low temperatures.

03

Heat Resistance

High temperature resistance is a priority for parts near the engine compartment.

04

Paint Compatibility

On visible exterior parts, surface quality and paint adhesion are important criteria.
