Typical applications of LWRT components in the automotive industry

LWRT is a lightweight, fiber-reinforced thermoplastic material known for its excellent thermal insulation, soundproofing, and high strength.
It is widely used in the automotive industry to reduce weight, enhance energy efficiency, and optimize vehicle performance.

Underbody Panels & Heat Shields

Heat protection: LWRT with aluminum foil is often used in underbody panels to shield sensitive vehicle components from exhaust heat.
Aerodynamic optimization: LWRT components help reduce air resistance, improving fuel efficiency and increasing the range of electric vehicles.
Corrosion resistance: Unlike metal parts, LWRT underbody panels do not corrode and have a long service life.

Interior Trim & Soundproofing

Floor mats and trunk liners: Lightweight Reinforced Thermoplastics are used for lightweight, sound-absorbing vehicle floor coverings.
Door panels and headliners: LWRT components enhance sound and vibration damping, improving driving comfort.
Consoles: Due to its moldability and durability, LWRT is ideal for complex-shaped interior components.

Wheel Arch Liners and Fender Liners

Weight savings: Compared to traditional materials, LWRT reduces vehicle weight and improves efficiency.

Resistance to moisture and dirt: LWRT components are waterproof and resistant to road debris, de-icing salts, and chemical exposure.
