Foamed silica gel is a two-component heating vulcanized silicone rubber, which is a white or skin-colored oily liquid. After vulcanization, it becomes a soft elastic material. The foaming volume is 3-4 times the original size; Pads, patches, anti-slip mats and other flexible silicone rubber products. Silicone foam is an environmentally friendly material, so it is also called addition-type silica gel. It is a food-grade certified product. It is composed of silica gel and curing agent at a ratio of 1:1. The product is safe and environmentally friendly. Its temperature resistance range is -40~220°C, its tear strength is as high as 55kN/m, and its elongation can reach 100%. In order to ensure the quality of the products produced, it must be operated in accordance with the construction requirements to avoid inappropriate quality problems.
So what are the secrets of the normal operation method of silicone foam? The specific operation method is as follows:


     1. The normal temperature of silica gel foaming is between 5 and 35 degrees Celsius. If we are constructing at low temperature, please put the product into warm water at 25 to 30 degrees Celsius in advance, and take it out after 5 minutes. This increases the temperature of the fuel tank.


     2. Do not directly contact with open flame and overheating.


     3. The surface must be cleaned, otherwise it will affect the bonding effect of silicone foam.


     4. Spray a small amount of water before operation to improve the ambient humidity.
