Silicone seal strips have become a popular solution for sealing doors, windows, gates and a variety of other automotive and industrial applications. Made from flexible silicone rubber, seal strips provide an effective barrier against air, dust, moisture, noise and even light.
Excellent Benefits Of Silicone Seal Strips
Silicone seal strips are made from high quality silicone rubber compounds that offer several benefits:
- Silicone rubber remains flexible within a wide operating temperature range from -60 to 300 degrees Fahrenheit, allowing it to conform to gaps and joints.
- Silicone seal strips can compress by up to 80% to form tight seals around gaps, joints and interfaces, blocking the transfer of air, dust and liquids.
- Silicone is resistant to environmental factors like UV exposure, moisture, ozone and chemicals as well as resistant to extreme temperatures, contributing to a long lifespan.
- When properly installed, silicone seals can last 10-20 years or more with minimal degradation due to silicone’s durability and resistance to deterioration.
- When compressed, silicone seals create a barrier that is impervious to water, dust and air filtration, providing an effective seal against external elements.
- Silicone seal strips help reduce sound transmission between two environments by absorbing and damping vibrations, providing acoustic insulation properties.
Top Characteristics Of Silicone Seal Strips
Silicone seal strips feature different characteristics to suit different applications:
- Closed-cell – Prevents air or fluid transfer through the seal. Used for high-performance weather sealing.
- Open-cell – Allows air transfer through small pores. Used for sound insulation and ventilation.
- Bulb seals – Have a circular cross-section to create a cushion seal. Used for higher tolerance gaps or dynamic applications.
- Fin seals – Have longitudinal fins that compress against surfaces. Used for straight gaps.
- Compressed seals – Are hollow when uncompressed. Used for higher compression ranges.
Common Uses For Silicone Seal Strips
Silicone seal strips are used in a variety of industries and applications:
- PVC door seal strip – Perimeter seals for garage, entry and service doors.
- Window seals – Sealing around windows, skylights and glass doors.
- Automotive seals – Seals for vehicle doors, trunks, moon roofs and HVAC vents.
- Flood/drainage seals – Sealing expansion joints, manhole covers and drainage channels.
- Industrial seals – Seals on machinery, assembly lines, conveyor belts and appliances.
- Commercial seals – Sealing gaps between floors, walls, ceilings and fixtures.
- Rooftop seals – Sealing air vents, rooftop hatches, ducts and skylights.
- Sound insulation – Reducing sound transmission through gaps and walls.
