Key features

Excellent Oil Resistance: The NBR compound resists gasoline, diesel, and hydraulic fluids, preventing swelling and cracking in automotive and industrial sealing applications.

Wide Temperature Range: Performs reliably from minus 40 to 120 degrees Celsius, maintaining flexibility in cold winters and sealing strength under hot engine conditions.

Superior Weather Durability: Withstands UV radiation, ozone, and rain without hardening or fading, making it ideal for long term outdoor door and window seals.

High Compression Recovery: The rubber rebounds quickly after compression, ensuring continuous contact pressure and a tight seal even after years of repeated opening and closing.

Waterproof and Dustproof: The dense NBR structure blocks water, dust, and air infiltration, protecting interiors from moisture damage and keeping machinery clean in harsh environments.

Vibration and Noise Damping: The soft rubber absorbs mechanical vibrations and reduces rattling sounds, improving comfort in vehicles and quieting industrial equipment enclosures.

Aging and Abrasion Resistance: Special antioxidants prevent premature hardening and surface wear, extending service life in high friction areas like sliding doors and trunk lids.

Easy Installation Options: Available with self adhesive backing or push in design, allowing quick mounting without special tools and reducing assembly time on production lines.

Versatile Application Fit: Suitable for car doors, windows, trunks, refrigerators, pipelines, and electrical cabinets, offering a single sealing solution for multiple industries.

Customizable Size and Shape: Can be extruded into various profiles and cut to any length, matching specific gap dimensions and customer requirements for a perfect fit.

AI-Powered supplier vetting

SummaryDongguan Gmark New Material Technology Co., Ltd. is a Chinese manufacturer/factory located in Dongguan, Guangdong. It provides 3D software design, ODM, OEM for well-known brands, SDK support, and broad customization services. The supplier reports no new products launched in the past year, while financial-record periods are identified for the previous three years without substantive performance figures. Overseas infrastructure is limited: no overseas agents or branches, warehouse, showroom, or offline trade-show participation, and zero countries listed for overseas services. After-sales activities include debugging, maintenance, repair, training, and equipment installation, but overseas delivery capability is not established. Lead time is stated as within 15 working days in both peak and off-season, and written procedures exist for supplier assessment, corrective actions, and complaint handling. Certification and formal quality-assurance status are not provided.

Supplier typeThe supplier is explicitly identified as a manufacturer/factory and a limited company based in Dongguan, Guangdong, China. Its associated-company industry is manufacturing, supporting classification as a direct manufacturing supplier rather than a trading-only entity.

After-Sales capabilityListed service activities include debugging, maintenance, repair, training, and equipment installation, and the supplier has documented procedures and records for handling customer complaints. However, it reports no overseas agents or branches, no overseas warehouse, no overseas showroom, and zero countries offering overseas services, limiting evidence of internationally localized support.

Production capacityThe supplier is a manufacturing factory and reports a peak- and off-season lead time within 15 working days. It has no in-stock capability, while outsourcing procedures and manufacturing-capacity contracts are marked unknown; therefore, production responsiveness is evidenced but overall capacity and supply-continuity controls are not fully established.

Customization capabilityThe supplier explicitly supports customization from samples, customization from designs, full customization, minor customization, flexible customization, ODM, and OEM services. These statements provide direct evidence of broad customization capability, supplemented by 3D software design and SDK support.

Client casesThe supplier states that it provides OEM services for well-known brands, which is direct evidence of at least one customer-reference category. However, no brand names, project details, quantities, or verifiable case studies are provided, so the depth of its customer track record cannot be assessed.
