Silicone foam board-all use silicone raw materials to add foaming agent and vulcanize through a high-temperature oven. During the vulcanization process, a large amount of air is generated, resulting in a large number of small holes inside the silicone. The biggest feature of the product is high temperature resistance and elasticity. Good, high-quality high-temperature-resistant foamed silicone strips can work at 350 degrees without qualitative changes. The surface tolerance is small, the foaming density is uniform, and the connection tension is good; the appearance is like sponge, it is extremely flexible, and the hand feels soft and does not hurt your hands. The smooth surface of the tube is bright and clean, rich in plastic luster, and the process can be unlimited length; the microporous material, the closed cell structure, does not absorb water, and is non-toxic. It can meet ROSH, FDA, 94V0 fire protection certification standards.
