Automotive & mobility
Automotive polypropylene goes into interior trim, instrument and door panels, bumpers and battery cases. Compounders also use it as a base resin. The OEM material specification sets the requirements for each part.

Automotive & mobility applications
Start from the part you make. Each page explains what the part asks of the polymer and lists the grades that fit.
A bumper that cracks in a cold impact, a trim panel that scratches or smells, a battery case that warps until the lid no longer seals: the OEM specification turns each failure into a test.
Start from the specification. Parts moulded from the base polymer are covered on automotive plastic parts, compounds on polymer compounding. The two routes read different data: a moulder checks the base polymer against the part's own tests, while a compounder checks it against the compound's own specification.
Each part family has its own weak point: surface and odour inside the cabin, cold impact outside, heat near the engine and the battery. EV battery housings and other energy-storage enclosures also need stiffness and fire safety, which in polypropylene points to glass-fibre or mineral-filled compounds.
Compounders choose by flow, form and impact. Many automotive plastics reach the car as a PP compound. An impact copolymer is the usual base for bumper compounds, and a high-flow homopolymer works as a flow modifier. Both need a melt flow that stays steady from batch to batch, so the recipe holds. Send us the specification and we will tell you which grades to test.

Not sure which grade fits?
Tell us the vehicle part, your current grade and the specification it must pass.
Material data for vehicle parts travels through IMDS, so we pass on the producer's IMDS reference and regulatory summary for your design file. Regulation (EU) 2026/1738 on end-of-life vehicles repeals Directive 2000/53/EC from 1 September 2028. It also sets recycled-content targets: new vehicle types type-approved from 1 September 2032 must contain at least 15% plastic recycled from post-consumer waste, rising to 25% from 1 September 2036. At least a fifth of that recycled plastic must come from end-of-life vehicles or from parts removed during the vehicle's use.

Common questions
We supply the polypropylene that goes into them: base resins, impact copolymers and high-flow homopolymers for compounders, in pellet or powder form. The talc-, glass- or elastomer-modified PP compound itself is made by the compounder and released against the carmaker's specification.
Polypropylene has the lowest density of the common commodity plastics, so a PP part weighs less than the same part in a denser plastic. Carmakers use it, neat or compounded, to take weight out of trim, bumpers and housings. Ask us which grades suit your part.
A blend of polypropylene with an elastomer, and often talc, made by a compounder. TPO compounds are used widely in bumpers and interior parts, and an impact copolymer is the usual base. We supply that base resin; the compounder qualifies the compound.
