Take you to know the sealing performance and environmental performance of silicone foam

 

Silicone foam has soft series foam material, fast rebound series foam material and hard series foam material. Energy management for sealing and gasket applications. Provides a higher level of vibration isolation protection for extreme demand environments. Silicone foam has the characteristics of light weight, and has the characteristics of enhanced sealing ability, durable elasticity, good cushioning and fire retardant of sponge rubber.

The long-term compression resistance of silicone foam sealing materials is an important factor affecting long-term seal durability, and choosing a material with excellent compression set resistance can help maintain a consistent closing force on the door panel or panel, resulting in a longer lasting seal Effect. Compression set resistance refers to the ability of an elastomer to return to its original thickness after the compressive load is released under a certain time and temperature. If the compression deformation of the gasket is large, the sealing effect may be affected by the reduction in the thickness of the gasket. This thickness loss usually occurs after a period of use and is not always apparent during the initial testing phase. Silicone foam has excellent creep resistance and exhibits excellent physical and sealing properties over the life of the product.

 

A successful silicone foam seal or gasket should have both chemical and solvent resistance, outgassing, temperature loading, flame retardancy, and sealing criteria. Fog and other environmental protection features, it will not contain plasticizers or other chemical residues that pollute the equipment, the material will not become fragile and brittle, and it is not corrosive to metals.
