Sponge profiles are used in places where merits of siloxane polymers (such as low temperature elasticity, heat resistance, UV and ozone resistance, and electrical completeness) are required. In addition, the special-shaped sponge has the advantages of light weight, good cushioning performance and heat insulation. The light weight of the special-shaped sponge determines that it needs less information. In today's fiercely competitive and demanding market, the special-shaped sponge can actually reduce the cost compared with synthetic rubber. Traditional silicone sponges can be consumed by adding evolutionary foaming agents to rubber. During vulcanization, heat can make the foaming agent synthesized, resulting in bubbles trapped in rubber, which constitutes the foam cell of sponge. These traditional foaming agents can produce toxic by-products.

New foam-blocking technology is used to replace traditional reactive chemical foaming agents and volatile organic compounds (VOC). This new type of sponge consumption technology uses water as foaming agent and can produce average cell structure. Its performance advantages include:

Elasticity;

_Low compaction deformation;

Eliminate the environmental factors related to sponge processing;

Reduce the use of exhaust system;

There is no unpleasant smell;

_Casual moulding and extrusion;

Average lubrication extrusion appearance;

_Sustainable food contact applications;
