Solid silica gel and foam silica gel contrast

Compared with solid silica gel, foamed silica gel has many special and valuable properties due to its special structure, namely porosity, such:

(1), the apparent density is small, light weight material province;

(2), rich in flexibility and softness, with excellent dust, waterproof and other sealing effect;

(3), improve the thermal insulation performance, with a lower thermal conductivity;

(4), improve the ability to absorb impact load, has excellent cushioning performance;

(5), improve sound insulation, sound absorption effect;

(6), improve the touch, improve comfort;

(7), a wide range of physical properties, change the apparent density or cell structure can get the corresponding performance of the sponge rubber. Therefore, foamed silicone products are widely used in many aspects such as sealing, shock absorption, heat insulation, sound insulation, printing and dyeing, and ion exchange. They are widely used in aviation, automobiles, instruments, meters, home appliances and packaging industries. Its shape is plate-shaped, strip-shaped, tubular, roller, gasket, etc., with various specifications and different shapes. Different use conditions require different hole structures and aperture sizes. For this reason, it is required to make corresponding adjustments in the formulation design and processing technology to achieve the corresponding performance.
