Extruded Rubber Silicon U Channel

Product overview

Core functionalities

Applicable scenarios

Unique advantages

  • Weatherproof & Waterproof Sealing: The U-shaped rubber-silicone design provides a tight seal against water, air drafts, and noise in doors, windows, and industrial panels.
  • Food-Grade Safety: FDA 21 CFR 177.2600 certification and BPA-free material ensure compliance for food-contact applications in commercial kitchens or processing equipment.

Key features

  • 1. Material Technology

    • With a durable rubber-silicone composite material, ensure long-lasting performance in harsh environments while maintaining flexibility for secure sealing. ~30% more resistant to UV and temperature extremes than single-material seals*

  • 2. Interactive Design

    • With a U-shaped design, easily install and adjust the seal strip without tools, adapting to various gaps and edges. Installation is 50% faster than traditional L-shaped seals*

  • 3. Performance Parameters

    • With a nonstandard extrusion process, achieve precise sealing performance tailored to specific project requirements. Customizable profiles ensure a 95% tighter seal than off-the-shelf options*

  • 4. Scenario Solutions

    • With adaptability for automotive, industrial, and household applications, provide a universal sealing solution for doors, windows, and panels. Versatile enough for both high-traffic commercial environments and residential use, reducing maintenance needs by 40% compared to standard seals*

  • 5. Certification Standards

    • With BPA-free and FDA 21 CFR 177.2600 certification, ensure compliance with food-grade safety regulations. Exceeds safety standards compared to non-certified alternatives, making it ideal for food processing and healthcare applications.

Supplier's note

  1. Technical Breakthroughs:

    • FDA Compliance: Enables safe use in food processing and medical equipment.
    • Pro Model Flexibility: 30% higher tensile strength than base models for heavy-duty sealing.
    • Custom Profiles: Extrusion capabilities allow bespoke shapes for niche applications.

  2. Version Selection Guidance:

    • Base Model: Suitable for standard residential or commercial sealing (e.g., door frames).
    • Advanced Model: Ideal for industrial environments with moderate chemical exposure (e.g., HVAC systems).
    • Pro Model: Designed for extreme conditions (e.g., automotive engines or marine equipment). With its tripled chemical resistance compared to industry benchmarks, the Pro Model ensures longevity in corrosive settings. Pair its high-temperature tolerance with silicone’s thermal stability to safeguard against thermal shock.
