Automotive Interior And Exterior PC Compounds

Interior and exterior trim parts in a passenger vehicle face two very different sets of demands at the same time. Inside the cabin, materials must keep odor and volatile emissions low, hold a clean high-quality surface and survive the heat soak behind the windshield. Outside the body, semi-exposed and exterior parts must resist long-term ultraviolet light, temperature cycling and stone impact without yellowing or losing gloss. Automotive Interior and Exterior PC Compounds are polycarbonate-based formulations developed to balance these requirements across the trim system. The interior direction emphasizes a low-VOC, low-odor package and a consistent molded appearance that fits dashboard garnishes, pillar trims and door components, where the part is touched and seen by every occupant. The exterior direction leans on a UV-stabilized, weatherable system that helps the part hold its color and surface finish under outdoor exposure. The base polycarbonate also contributes the impact energy absorption that protects trim against stone chips and cold-temperature handling, which is why PC is a common choice for structural and semi-structural automotive components rather than purely decorative ones. Because interior and exterior parts are often molded in the same plant, the compounds are tuned for stable injection behavior on multi-cavity tools, so color, gloss and fit remain consistent across long production runs and across the different geometries of the cabin.

For trim suppliers, the value lies in matching the formulation to each part rather than applying one generic grade across the cabin. We build the weathering and low-VOC package together and tune flow behavior to the geometry of your specific trim piece. We also develop the compound against your technical drawings or physical prototypes, so the color, texture and mold flow align with the assembled interior or exterior design before production starts, and samples that match mass-production quality are available for your confirmation early in the project.

Interior trim and garnish

A low-VOC, low-odor formulation supports cabin air quality requirements while the molded surface holds a premium look on dashboard and pillar parts.

Exterior semi-exposed trim

The UV-stabilized weatherable grade resists yellowing and gloss loss on body-side claddings and mirror-area trim exposed to sunlight.

Door and side cladding parts

Impact-modified PC absorbs stone-chip and cold-day handling energy, reducing breakage on trim that meets the road.

Color and texture finish; low-VOC / low-odor level; UV stabilization package; interior-grade versus exterior-grade balance; mold-flow tuning per part geometry.

Polycarbonate granules are packed in standard export bags, loaded on pallets as needed, and secured for ocean or air freight. Bagging, labeling and palletization are arranged to the customer's international shipping requirements. We support EXW (buyer collects from factory), FOB (factory covers transport to port and export clearance), and DDP (delivered duty paid to the buyer's warehouse).
