Lightweight Reinforced Thermoplastic Materials for Automotive Parcel Shelves, Engine Under Covers

Home » LWRT Series

LWRT materials play an increasingly important role in both traditional gasoline-powered vehicles (ICE) and modern electric vehicles (EV), and are widely used in various automotive components.

LWRT can be combined with various surface materials such as:

  • Non-woven fabrics.
  • Woven fabrics.
  • Suede-like materials.

Product Features

  • Lightweight

Low density, reducing weight by approximately 20%–40% compared to traditional fiberglass substrates, contributing to overall vehicle weight reduction, lower fuel consumption, or improved range for new energy vehicles.

  • Excellent Mechanical Properties

High bending strength, impact resistance, and dimensional stability.

  • Durability

Resistant to water absorption and mold growth, resistant to damp heat, and more stable than traditional foaming systems.

  • Good Molding Performance

Can be hot-pressed into complex curved surfaces in one step.

  • Noise Reduction and Sound Absorption

LWRT material has a porous structure, providing excellent absorption of mid-to-high frequency noise.

  • Environmentally Friendly and Recyclable

LWRT material is recyclable and has low VOC emissions during production.
