Premium Product Features & Properties

Our rubber pinch weld edge trims are engineered with superior physical and chemical properties to adapt to complex working environments, ensuring reliable sealing and protection performance all year round.


  • Excellent Ozone Resistance: Prevents rubber cracking and aging caused by ozone exposure, ideal for long-term outdoor installation.

  • Strong UV Resistance: Resists ultraviolet radiation damage, avoiding discoloration, hardening and performance degradation under direct sunlight.

  • All-Weather Weathering Resistance: Adapts to variable temperature and weather changes, maintains stable flexibility and sealing performance in rainy, windy and harsh climatic environments.

  • Anti-Bacterial & Anti-Mould Performance: Effectively inhibits bacterial and mould growth, suitable for humid outdoor and semi-outdoor scenarios.

  • Alkali Corrosion Resistance: Tolerates alkaline substances erosion, extending service life in industrial and complex environmental conditions.

  • Dust & Water Sealing Protection: Tightly fits various material edges to block water splashing, rain penetration and dust entry, improving overall tightness.


    Custom Material Options for Pinch Welds

    We offer multiple professional rubber material formulations to match different application scenarios, meeting your requirements for temperature resistance, corrosion resistance and usage environment:


    • EPDM Rubber: Best for outdoor weather resistance, UV and ozone proof, widely used for automotive and outdoor equipment sealing.

    • Neoprene Rubber: Balanced weather and chemical resistance, ideal for marine and general industrial applications.

    • Nitrile Rubber: Features excellent oil and abrasion resistance, suitable for industrial mechanical edge protection.

    • Silicone Rubber: High and low temperature resistant, non-toxic and aging-resistant for special high-standard usage scenarios.

    Standardized Pallets: Goods are stacked on heat-treated (ISPM 15) or plastic pallets, optimized for forklift handling. Rigid Corner Protectors: High-impact cardboard corner guards are applied to the full height of the stack. This prevents the straps from cutting into the rubber and maintains the vertical integrity of the pallet.
