Silicone Profiles
Precision extruded silicone rubber profiles engineered for commercial baking ovens, industrial autoclaves, LED luminaires, and solar equipment. Retains supreme flexibility and recovery across extreme thermal swings from -60°C to +250°C.
Types & Configurations of Silicone Profiles
Tadpole & Flanged Oven Door Seals
Tadpole-shaped silicone profiles with fabric core or mounting tail for high-temperature oven doors.
E-Type & P-Type Compression Gaskets
Engineered bulb profiles providing soft, resilient closing action on autoclave hatches.
Inflatable Pneumatic Silicone Seals
Hollow elastomeric profiles inflated by air pressure to hermetically seal cleanroom doors.
LED Lighting Waterproof Edge Seals
Translucent optical silicone channel profiles sealing outdoor architectural luminaires.
Co-Extruded Conductive Silicone Profiles
Nickel-graphite filled silicone profiles providing combined environmental and EMI shielding.
