Which Materials Are Best For Automotive Interior Components?

Top Choices for Structural Components
Modified PP (Polypropylene): The most widely used base material for automotive interiors. It is non-toxic, odorless, low-cost, easy to process, and chemically resistant. Suitable for the vast majority of basic interior components-such as dashboard cores, door trim panels, storage compartments, and center console armrests-it is the mainstream choice for mass-produced vehicles.
ABS / ABS+PC Alloy: Offers high strength and excellent wear resistance. The surface is easily painted or electroplated. Suitable for components requiring specific aesthetics and rigidity-such as instrument clusters, center console panels, and control buttons-it balances premium feel with practicality.

 

Top Choices for Upholstery and Tactile Surfaces
Top-Grain Nappa Leather: Soft and skin-friendly, wear-resistant, and stain-resistant. It offers year-round comfort-breathable in summer and not cold to the touch in winter-and spills wipe off easily. Ideal for high-contact areas like seats and steering wheels, it is the preferred choice for business-class vehicles and consumers seeking a premium feel; with regular care, it offers long-lasting durability.
Water-based PU Synthetic Leather: Features low VOC emissions throughout the entire production chain-emitting only one-fifth of standard levels-making it exceptionally eco-friendly. It combines the tactile feel of leather with durability, serving as a mainstream, environmentally friendly upholstery material for applications such as seats and door panel coverings.
Alcantara Synthetic Fabric: Composed of 68% polyester and 32% polyurethane, it offers high friction and excellent slip resistance while reducing glare and absorbing noise. Suitable for areas requiring good grip-such as steering wheels and seat bolsters-it is widely used in sporty vehicle models.
