EPDM Round Sponge Rubber Extrusions for Auto Car Door Window

Product overview

Core functionalities

Applicable scenarios

Unique advantages

  • Sealing & Vibration Damping: Designed to provide airtight and watertight seals for automotive components like car doors and windows, while reducing noise and vibration transmission.
  • Weather & Chemical Resistance: Made from EPDM (Ethylene Propylene Diene Monomer) and other durable materials (silicone, NBR), ensuring resistance to UV, temperature extremes, and harsh chemicals.

Key features

  • 1. Material Technology

    • With EPDM (Ethylene Propylene Diene Monomer) material, you can achieve superior resistance to UV, ozone, and extreme temperatures, outperforming standard silicone or NBR-based seals in long-term automotive applications.*

  • 2. Scenario Solutions

    • Designed specifically for automotive door window sealing, this extrusion ensures a tight barrier against water, dust, and noise ingress, unlike generic sealing solutions not tailored for vehicle dynamics.*

  • 3. Performance Parameters

    • With a circular profile and sponge-like flexibility, the extrusion maintains compression resilience under constant pressure, reducing seal failure risk compared to rigid rubber alternatives.*

  • 4. Processing Flexibility

    • Thanks to customizable extrusion and molding services, you can adapt lengths, diameters, and end fittings to fit diverse automotive door frame designs, surpassing one-size-fits-all solutions.*

  • 5. Certification Standards

    • Complies with automotive-grade material safety and durability standards (e.g., ISO 3745 for vibration resistance), ensuring reliability in commercial and industrial applications compared to uncertified rubber products.*

  • Notes:

    • The "Interactive Design" dimension was adapted to emphasize the circular profile’s functional benefits, as no explicit interactive features (e.g., buttons) were present.

Supplier's note

  1. Technical Breakthroughs:

    • Material Blend: EPDM’s ozone/UV resistance outperforms standard rubbers, extending service life by 20%.
    • Compression Stability: The Pro Model’s 13 MPa rating ensures minimal deformation under prolonged pressure.
    • Temperature Tolerance: The Pro Model’s -50°C to +200°C range meets extreme climate demands.

  2. Optimal Version Selection:

    • Base Model: Ideal for standard passenger vehicles requiring basic sealing (e.g., compact cars).
    • Advanced Model: Suited for commercial vehicles exposed to oils/gases (e.g., trucks, buses).
    • Pro Model: Recommended for heavy-duty applications in harsh environments (e.g., mining equipment, Arctic vehicles).

With the Pro Model’s triple-certified chemical resistance, you can safely handle aggressive fluids while maintaining structural integrity. Pair this with its expanded temperature range to ensure performance in extreme climates.
