Which Automotive Interior Materials Are Most Popular?

Based on 2026 market feedback and user research data, TPE, modified PP, and microfiber leather stand out as the three most popular materials for automotive interior components, with each excelling in specific use cases:

 

Highly Popular Materials Across All Scenarios
TPE (Thermoplastic Elastomer): The top choice for family vehicles in 2026. Virgin TPE-free from recycled content and formaldehyde-is eco-friendly and odorless. It is waterproof, stain-resistant, and easy to clean; spills like milk or beverages can be wiped away instantly with a wet cloth. Ideal for high-contact components such as floor mats and seat cushions, it enjoys an excellent reputation among families with children and odor-sensitive users, with related products consistently achieving overall user satisfaction scores of 8 or higher in 2026.
Modified PP (Polypropylene): The mainstream choice for mass-produced vehicle interiors. It minimizes in-cabin odors and reduces the likelihood of rattling noises from trim panels when driving over rough roads. Dashboards made from this material resist whitening and deformation after prolonged sun exposure. Balancing lightweight properties, low cost, and durability, it is the most widely used material for OEM interior components, covering the vast majority of basic parts such as dashboards and door panels.

 

Popular Materials for High-End Customization

Microfiber Leather: Highly popular for seat and door panel upholstery upgrades. It offers excellent breathability and superior resistance to temperature fluctuations-resisting aging under intense sun and cracking in cold weather. Its resistance to repeated flexing and hydrolysis far surpasses that of standard PU leather. Available in a wide range of colors and textures to match various interior styles, it also meets environmental safety standards for automotive interiors, making it a mainstream choice for interior customization in major cities.
