General Applications of Closed-cell Silicone Sponge Profiles:
The silicone sponge extrusion profiles are featured by excellent insulating, sealing as well as flame-retardant properties, which makes them an ideal choice for multiple industries such as household appliances, toys, hardware, medical equipment, sports products, machinery, automobile, bottle sealing, curtain wall for construction, etc. It also has wide applications in outdoor lighting gaskets, electrical enclosure seals, window seals, door seals, oven door seals, cooling and heating installations, shock absorbing cushions, hob seals, etc.
Key Features of Silicone Sponge Extrusions:
- Good sealing capabilities. It has effective resistance to water, dust, insects, etc., prevent bacteria and germs building up to bring a more hygienic environment.
- Excellent resistance to temperature extremes which makes the strips work under high and low temperature from -60°C – +250°
- Non-toxic and odourless. It is FDA approved for safe contact with food.
- Pliable, flexible and soft materials are featured by low compression set and high resilience performance, which leads to durable service.
- Superior flamability properties, which offer a safe barrier against dangerous fire.
Advantages of Silicone Sponge Strips including:
— Amazing sealing capabilities
— Good Ozone & UV resistance
— Excellent shock absorption performance
— Effective flexibility in design
— Highly durable with good compression & recovery attributes
— Low, medium or high density ranges available
— Higher thermal insulation properties
— We offer a range of silicone sponge profiles in a variety of shapes, sizes and densities, including self-adhesive type, round type, rectangular type, irregular type, etc.
Why choose our silicone sponge extrusions?
Our silicone sponge extrusion is made of a soft, pliable and flexible material, which makes it waterproof and airtight to suit different applications. The extruded silicone sponge has excellent flammability and high temperature resistance, which is able to withstand high and low temperature range from -60°C to -250°C. We can offer strips with a width ranging from 5mm to 150mm and in thickness from 1mm to 50mm. The product has come with the standard lengths available in 10 meters and with the larger sizes in 2x5m. The strips can be packed in rolls or cut to a shorter size or desired length, and the length can be customized.
Our silicone sponge strip is a closed-cell elastomer material, which is expanded when it is heat cured to generate many tiny bubbles that are not connected through the passage of the material. This creates a tight seal to prevent air and liquid from passing through the material, providing a superior sealing capabilities. The material also offers a safe barrier against bacteria and mildew buildup, making the strips a more hygienic use.
