As a non-toxic and odorless environment-friendly material, silicone rubber is widely used with its various excellent properties. Various products made from silicone rubber are constantly appearing in our daily life.

Silicone rubber foam, also known as addition molding silicone rubber, is a kind of porous rubber structure product, which is made of silicone rubber as the base material and produced by foaming method. Its section is similar to honeycomb structure and has good resilience and mechanical strength.

The density of silica gel foam (0.3-0.7g/cm3), its service life is long, and its pressure resistance, acid and alkali resistance, aging resistance, ultraviolet resistance, high and low temperature resistance, environmental protection, non-toxic and tasteless, and good flexibility.
Silicone rubber foam is a highly active adsorption material, insoluble in any solvent, stable in chemical properties, good in dielectric properties and insulation properties.

The temperature range is wide, ranging from - 60 ℃ (or lower temperature) to+250 ℃ (or higher temperature).
The principle of foaming silicone rubber is to add foaming agent into the selected silicone rubber compound, and heat and vulcanize the silicone rubber under pressure to make the silicone rubber foam, and the rubber compound expands to form a spongy foam structure.   
Silicone rubber foaming needs to go through a series of production processes and processing processes, and each link will have an impact on the finished products of silica gel foaming.   

Silicone foam products have excellent heat and cold resistance, high adsorption performance, high mechanical strength and good thermal stability. In addition, foamed silicone rubber has the characteristics of lightweight, damping and heat insulation.
Therefore, it is often used in occasions with low temperature, heat resistance, UV resistance, ozone resistance and good electrical insulation. For example: automobile, aerospace, computer, mechanical equipment, electronic industry, kitchen appliances, household appliances and other equipment. With the continuous development and update of foaming technology, and due to its superior characteristics, the product types of foaming silicone rubber are more and more extensive, such as vibration isolation materials and protective equipment such as sealing strips, cushion pads, sealing rings, foaming pipes, gaskets, etc.

Silicone foam sealing strip:
Silicone foam sealing strip belongs to extrusion products and is a common sealing piece. It is mainly used for textile printing and dyeing equipment, drying equipment, special-shaped door sealing strip, advanced oven, high-end vehicle doors and windows, building glass, etc. Various specifications and shapes can be customized and can be used with adhesive backing.

Silicone foam sealing ring:
Silicone foam sealing ring is a molded product, which is one of the silicone sealing components to prevent external dust, air, water, etc. from entering the system. It is mainly used for waterproof sealing of display screen, electronic screen, LCD screen, street lamp signboard and other products.

Silicone foam pipe:
Silicone foam pipe is an extrusion product. Because of its uniform foaming, good elasticity, and good flexibility, it has high sealing and extrudability and good sticking height! It can be used in supporting electronic appliances, furniture equipment, toys, hardware, medical equipment, sporting goods, audio, lighting, machinery, automobile, industrial construction and other industries.

Silicone foam board:
Silicone foam board has strong sealing ability, dust prevention, moisture prevention, fire prevention, airtight and light shielding, and can effectively prevent small particles and rain. It can be used in electronic and vehicle internal vibration isolation, hot stamping printing equipment, mechanical seal, medical equipment and other industries. It can be used for shock absorption, cushioning and pressing. It can also punch various sealing washers and backing plates with strict requirements, and die cut into any shape of sheet according to different requirements of customers.
