Silicone Rubber Gaskets
Industrial gaskets made of silicone rubber (VMQ), custom manufactured to technical drawing or sample, with stability over a very wide thermal range and high chemical inertness. The recommended solution for equipment with extreme temperatures and electrical/electronic applications.
Technical Specifications
Indicative values for the finished gasket, depending on geometry and recipe. Exact parameters are determined according to the application and the dimensions in the technical drawing.

Applications
Food and pharmaceutical industry
Chemical inertness and biocompatibility; food-contact compliance is confirmed separately per recipe.
Extreme-temperature equipment
Ovens and severe thermal cycles, where heat stability is essential.
Electrical/electronic
Thermal insulation and long-term stability for electrical components.
Frequently Asked Questions
Why are silicone gaskets chosen for extreme temperatures?
Silicone rubber (VMQ) is stable over a very wide thermal range, typically -60°C to +200°C for the finished gasket, with excellent resistance to ozone and UV.
Are silicone gaskets safe for food contact?
Certain silicone recipes are suitable for food contact, but compliance depends on the formulation and is confirmed separately, on request — it is not implicit for all silicone gaskets.
How does the mechanical strength of silicone gaskets compare to NBR or EPDM?
Tensile strength is lower than NBR or EPDM. Silicone is chosen for extreme temperature and chemical inertness, not for intense mechanical loading.
Can you produce colored or specially shaped silicone gaskets?
Yes — we manufacture to order, based on a technical drawing or sample, including colored variants.
