Key Features
- Automotive-Grade Material: Manufactured from high-density polyethylene (PE), this cushion strip delivers excellent impact resistance, low-temperature flexibility, and superior durability. PE offers a balance of toughness, chemical resistance, and cost-effectiveness, making it ideal for demanding automotive environments.
- Custom Extrusion Capability: Tailored to meet exact dimensional, profile, and performance requirements. From simple U-channels to complex multi-void geometries, we offer precision extrusion with tight tolerances (±0.15 mm typical).
- Weather & UV Resistance: Formulated with UV stabilizers and antioxidants, the PE compound ensures long-term performance in outdoor and under-hood applications, resisting degradation from sunlight, ozone, and temperature extremes (-40°C to +80°C continuous).
- Low Compression Set: Maintains sealing and cushioning properties over prolonged compression, minimizing deformation in door seals, trim, and gasketing applications.
- Noise & Vibration Damping: Engineered to absorb mechanical vibrations and reduce operational noise, enhancing cabin comfort and component longevity.
- Compliance & Quality: Meets or exceeds industry standards for automotive interior and exterior components, including ISO 9001:2015 quality management and RoHS compliance.
