Material Selection Guide
Choosing the right rubber polymer compound is essential to ensure longevity and prevent seals from failing under pressure.
EPDM Sponge
Highly compressible, lightweight, and soft. Ideal for weather-stripping door and lid closures, electrical panels, and sound dampening.
EPDM Solid
High mechanical durability and weather resistance. Excellent ozone and UV stability. Used in outdoor glass sealing, auto window channels, and enclosures.
Silicone (VMQ)
Perfect for high-temperature cleanroom ovens, food-grade processing lines, and autoclave seals. Retains elasticity from -60°C to +230°C.
Nitrile (NBR)
Excellent oil, diesel, and grease resistance. Formulated for sealing automotive fuel tanks, gearboxes, and industrial hydraulics.
Applications & Custom Capabilities
- Custom Die Design: Rapid prototyping and tool engineering to manufacture custom shapes from sketches or samples.
- Corner Vulcanization: In-house splicing presses to join profiles into seamless, water-tight rectangular gaskets.
- In-Line Taping: Application of pressure-sensitive adhesive (PSA) or heavy-duty 3M tape to the profile base for easy mounting.
- Laser Inspection: Live laser dimensions checking on the extrusion line to ensure profile accuracy and consistent cross-sections.
