Meeting the Sealing Challenges of Modern Automotive & New Energy Industries

The automotive and new energy sectors demand sealing solutions that can withstand extreme temperatures, chemical exposure, and constant vibration—all while meeting strict safety and regulatory standards. Our custom silicone extruded gaskets and seals are engineered to address these critical challenges, providing long-lasting performance for key components in traditional vehicles, electric vehicles (EVs), and hybrid models.

1. Targeted Solutions for Core Automotive Applications

• EV Battery Sealing: EV battery packs require seals that resist high temperatures (up to 315°C) and prevent moisture intrusion—our platinum-cured, UL 94-V0 flame-retardant silicone tubes are designed specifically for this purpose. A European automotive Tier 1 supplier relies on our high-precision extruded seals to meet their battery module’s strict tolerance requirements, ensuring thermal stability and compliance with global safety standards.
• Door, Trunk & Window Seals: Our D-shaped, U-channel, and bulb seals are customized to fit vehicle body contours, reducing wind noise, blocking dust, and enhancing thermal insulation. With adjustable Shore A hardness (from 30A to 80A), we tailor flexibility to ensure easy installation while maintaining long-term compression set resistance.
• Noise & Vibration Dampening: Sponge silicone extrusions with multi-durometer layers are used in engine bays and chassis components to absorb vibrations, improving ride comfort and reducing component wear. These seals are formulated to resist oil, grease, and road chemicals, ensuring durability even in harsh undercarriage environments.

2. Why Silicone Stands Out for Automotive Use

Silicone’s inherent properties make it superior to traditional rubber for automotive sealing:

• Extreme Temperature Resistance: Performs reliably from -60°C to 315°C, ideal for engine compartments and EV battery systems.
• Weather & UV Resistance: Maintains elasticity and sealing performance after years of exposure to sunlight, rain, and snow.
• Regulatory Compliance: All automotive-grade seals meet RoHS, REACH, and UL standards, with FDA-compliant options available for interior components.

3. Partnering for Automotive Innovation

We work closely with automotive OEMs and Tier 1 suppliers to support new vehicle development. Our fast tooling capabilities (3–5 days for custom dies) enable quick prototyping of seals for new models, while our high-volume production lines (up to 30,000 meters daily) ensure on-time delivery for mass production. Whether you’re designing a next-gen EV or upgrading a traditional vehicle’s sealing system, our custom solutions deliver the reliability and performance your products demand.
