What is liquid silicone?

Liquid silicone is a two-component system composed of long-chain polysiloxanes and specially treated silica. It has many excellent properties, such as non-toxic, high temperature resistance, anti-aging, and close to human hand feel. Mainly used in industries such as aerospace, medical, 3C waterproofing, and food. For example, seals for rocket spacecraft, smartphones, waterproof components for wearable devices, medical equipment, baby pacifiers, etc.

Liquid silicone has various excellent properties:

High temperature resistance: It can be used for a long time at 200 ° C, and its dielectric properties are almost independent of temperature in the range of 20-200 ° C.

Low temperature resistance: still elastic at -60 ° C.

Ozone resistance and UV resistance: Will not rupture when used outdoors for a long time.

Excellent weather resistance: can be used outdoors for a long time.

Good electrical insulation performance: Silicone rubber has excellent dielectric properties, especially at high temperatures, which are much higher than ordinary organic rubber.

Good processing performance: easy to shape, can be produced by methods such as extrusion hot air vulcanization molding, mold addition molding, and extension molding.

Moderate viscosity and good fluidity: easy to operate, with high transparency of the product.

Tear resistance and resilience: Liquid silicone has high tear resistance and resilience, and can withstand large pressures and impacts.

Resistance to yellowing and thermal stability: Liquid silicone is not prone to yellowing at high temperatures and has good thermal stability.

Good water resistance and breathability: Liquid silicone has good water resistance and breathability, which can keep the product dry and comfortable.

Liquid silicone is widely used in industries such as aerospace, medical, 3C waterproofing, and food.

In addition to the excellent performance mentioned above, liquid silicone also has some other characteristics:

Non toxic and odorless: Liquid silicone is a non-toxic, odorless, colorless, transparent or semi transparent material that will not have any harmful effects on human health.

Environmental performance: Liquid silicone does not use any harmful solvents during the production process, so it has good environmental performance and can meet the green production needs of modern society.

Corrosion resistance: Liquid silicone has good corrosion resistance and can resist the erosion of most chemical substances, such as acids, alkalis, salts, etc.

Wear resistance: Liquid silicone has good wear resistance and can maintain its appearance and performance stability over long-term use.

Aging resistance: liquid silica gel has good aging resistance, which can keep its performance stable in long-term use.

Processability: Liquid silicone has good processing performance and can be used for processing operations such as injection molding, extrusion, and rolling, making it convenient and fast.
