Automotive Interior Plastic Materials for Low VOC, Appearance and Dimensional Stability
Select modified PP, ABS, PC/ABS and functional masterbatch systems for dashboard components, door panels, trim, control housings, brackets and interior molded parts requiring low odor direction, surface quality, impact strength and stable injection molding.
Interior material selection is a balance of performance and cabin quality
Automotive interior plastics must support manufacturing efficiency and long-term part performance while also meeting appearance, odor, VOC, aging and assembly expectations. The right grade depends on part location, load, finish, heat exposure and molding risk.

FAQ
What plastics are commonly used for automotive interior parts?
Common automotive interior plastics include modified PP, reinforced PP, ABS, PC/ABS, PA, TPO and flame retardant compounds depending on part function, appearance, heat exposure, odor/VOC target and assembly requirements.
Why are low VOC and odor requirements important for car interior plastics?
Interior plastic materials can affect cabin air quality and customer perception. OEM specifications often require low odor, low VOC direction and controlled emissions, especially for dashboard, door panel and console materials.
When should PC/ABS be selected for automotive interiors?
PC/ABS is often selected when interior parts need higher toughness, heat resistance, dimensional stability or stress-cracking resistance than standard ABS or PP can provide.
Can material formulation reduce interior part warpage and sink marks?
Yes. Material formulation can help by adjusting shrinkage, reinforcement, impact modifiers, flow behavior and processing stability, but part design, gate location, cooling balance and molding parameters should also be reviewed.
