Material
We utilize a comprehensive range of premium elastomers to ensure optimal performance for every application:
- EPDM (Dense & Sponge): Ideal for weatherstripping, door seals, and automotive components, offering exceptional resistance to ozone, UV rays, and extreme temperatures.
- Nitrile Rubber (NBR): Perfect for fuel hoses, gaskets, and oil-resistant parts, providing excellent durability in petroleum-based environments.
- Silicone Rubber: Suited for high-temperature applications such as engine components and marine seals, with superior flexibility and thermal stability.
- Thermoplastic Vulcanizates (TPV): A lightweight, cost-effective alternative to traditional rubber, ideal for glass run channels and automotive trim seals with enhanced abrasion resistance.
- PVC & Nylon 66/6: Used for edge protection trims and rigid structural components, combining strength with impact resistance.
Feature
Our custom rubber extrusions are engineered with precision and performance in mind:
- Tight Tolerances: Compliant with RMA precision standards, ensuring consistent fit and functionality across all products.
- Versatile Design Capabilities: From solid profiles to dual-durometer co-extrusions, we accommodate complex shapes and multi-material combinations.
- Enhanced Durability: Advanced formulations deliver superior resistance to weathering, chemicals, and wear, extending product lifespan.
- Value-Added Finishing: Options including flocking, low-friction slip coating, PSA backing, and custom printing to meet specific application needs.
- Fire Retardancy: Specialized formulations available for rail and mass transit applications, meeting strict safety regulations.
Application
Our solutions cater to diverse industries worldwide:
- Automotive: Door/window weatherstrips, glass run channels, trunk seals, and engine components, designed to reduce noise, vibration, and harshness (NVH).
- Rail & Mass Transit: Fire-retardant door seals, window gaskets, and cabin insulation components, ensuring passenger safety and comfort.
- Marine: Watertight hatch seals, window glazing gaskets, and deck equipment components, engineered to withstand saltwater corrosion and extreme weather.
- Home Appliances: Refrigerator door gaskets, dishwasher seals, and HVAC components, ensuring energy efficiency and leak prevention.
- Industrial: Custom gaskets, conveyor belt components, and machinery seals, tailored to withstand heavy-duty operating conditions.
Capabilities
