Take you to understand the sealing effect and compressibility of silicone foam

 

Silicone foam has excellent anti-compression deformation properties, maintains reliable working pressure to evenly fill and seal voids, and prevents the collapse of raw materials due to compression working pressure and temperature during long-term application. Flexible yet reliable, yet durable, this serviceable interstitial foam can be used to fill voids that are likely to arise due to shifts in manufacturing dimensional tolerances or environmental damage under a variety of practical operating standards.

Silicone foam gaskets are compressible enough to achieve the specified level of sealing, and the sufficient compressibility and creep resistance of the silicone foam keeps loads within specified limits while being able to accommodate a wider range of compression intervals. Whether it is rail transit, aerospace or industrial housing, the seals or gaskets of the housing need to be in close contact with the surface of the housing, and there should be no gaps. If the silicone foam sealing gasket leaks and needs to be replaced, it will not only cause the parts to be damaged. In addition, it may lead to the loss of enclosure certification, which is a very inefficient thing that increases expenses and wastes time. Silicone foam has superior compressibility, anti-creep performance and conformal fit that ordinary foam does not have, and can effectively seal during product use. Both materials are available in a variety of hardnesses and thicknesses to ensure robust sealing performance designs.

 

Silicone foam is specially designed for some working environments that require gaskets with extremely high strength and durability. The product itself has high tensile strength, high elongation at break, low compression set rate, smooth and flat surface, suitable for lamination and coating. Covered with adhesive. Silicone foam is required to be strong enough. In the harsh environment where silicone foam is required, its performance requirements exceed similar competitive products. Silicone foam generally has the following characteristics and advantages:

 

characteristic

• Thickness range of 0.094-0.5 inches

• 205°C (401°F) for continuous use and 260°C (500°F) for intermittent use

• Low temperature embrittlement point of -55°C (-67°F)

• Waterproof down to 15% compression

• Meets the most stringent UL gasket certifications

 

Advantage

• Can withstand the toughest applications and the most extreme conditions

• Stretch up to 175% (before material failure)

• Provides excellent long-term watertight performance

• Continuous coil production means higher productivity

• Combines high tensile strength and abrasion resistance
