Silicone offers inherent resistance to ozone, UV exposure, and weathering. Material maintains flexibility across extreme temperatures and exhibits low chemical reactivity with most industrial substances.
Manufacturing Process
Compression molded production ensures uniform density and minimal parting lines. This method yields precise dimensional control for applications requiring consistent compression forces and repeatable seal integrity. Tooling accommodates both low-volume prototyping and high-volume production runs.
Typical Applications
HVAC system seals and gaskets
Food processing equipment (FDA-grade silicone available)
Pharmaceutical cleanroom fixtures
Electrical enclosure environmental seals
Automotive lighting assemblies
Industrial oven and furnace door seals
Customization Capabilities
Standard profiles include:
O-ring cord stock (various cross-sections)
Rectangular and square cross-sections
Flat sheet gaskets (waterjet or die-cut)
Complex geometries with molded features
