Silicone, to most people, may be an unfamiliar name, but in fact, it has already unknowingly penetrated all aspects of our lives, from the clothes we wear, to the food we eat, the house we live in, and the The high-speed trains you take, the roads you walk, and the bridges you cross all use silicone materials. We have long been inseparable from silicone, so how close is silicone to our lives?
Daily chemical products
Silicone has the characteristics of high temperature resistance and bacteria resistance, and is used in baking molds, heat-proof gloves, compressible food containers and duckbill cups.
The silicone teether is soft, which can also relieve the discomfort of the gums when the baby is teething. It can also prevent the baby from biting his fingers or other items that are unsanitary and cause bacterial infection. There are many benefits.
Silicone has stickiness and ductility, which is conducive to the diffusion of cosmetics on the skin surface, and can maintain the normal ventilation of the skin. The silicon in makeup products, especially in base makeup products, can hide the pores on the skin and smooth the skin texture.
Shampoo and hair care products:
It can give hair luster, easy combing, smoothness, antistatic and soft feeling. In fact, many brands of shampoos contain silicon.
Detergent and fabric softener:
Silicone has defoaming properties, which can reduce the water consumption and energy consumption of washing machines.
Silicone has excellent electrical insulation and long-lasting elasticity, toughness and adaptability. Silicone sealants, adhesives and coatings are used in the production of circuits, connectors, capacitors, coils, transistors and tubes in electronic devices. Silicone protects various electronic components from heat, shock and contamination.
Silicone is hydrophobic, hypoallergenic, durable and easy to disinfect, and does not react with most chemicals. Silicones are widely used in dental impressions, prosthetics, respirators, intravenous drugs and blood transfusion systems, ventilation masks and other medical fields. At the same time, it can promote wound healing, improve the appearance of existing scars, reduce discomfort, and reduce patient risk.
Silicone has outstanding water resistance and thermal stability.
①Under the hood of the car, silicone rubber protects the electronic components from moisture and dirt.
②In airbags, silicone improves airtight sealing and fabric strength, helping airbags inflate at precise timing and pressure.
③In new energy vehicles, organic silicon is used for the packaging of the entire battery pack, which plays the role of stability, anti-vibration, heat dissipation, waterproof and dustproof.
Silicones have excellent properties such as transparency, stability, low reactivity, and resistance to UV radiation. In solar panels, silicones can be used as conductive adhesives and encapsulants, which not only improve the efficiency of solar panels, but also reduce maintenance costs and extend service life.
What is silicon?
Silicon is an important petrochemical substitute material, energy material and electronic material. The crustal abundance of silicon is 27%, second only to oxygen (46%), and about 1,000 times that of carbon. It is extremely rich in resources and has huge development potential. There are two allotropes of amorphous silicon and crystalline silicon. Crystalline silicon is gray-black, amorphous silicon is black, the density is 2.32-2.34 g/cm3, the melting point is 1410°C, and the boiling point is 2355°C. Crystalline silicon is an atomic crystal. Insoluble in water, nitric acid and hydrochloric acid, soluble in hydrofluoric acid and lye. Hard and metallic.
What is Silicone?
Organosilicon refers to a compound containing Si-C bonds and at least one organic group is directly connected to a silicon atom. It is customary to treat compounds in which an organic group is connected to a silicon atom through oxygen, sulfur, nitrogen, etc. Organosilicon compounds.
What is the development prospect of silicone?
Silicone is less dependent on oil and natural gas and is an ideal substitute for petroleum-based synthetic materials. Accelerating the substitution of silicones for petroleum-based synthetic materials has both broad market prospects and important strategic significance. In the future, among the many downstream application fields of silicone, construction, electronic appliances, textiles, personal care, etc. will still be the main application fields of silicone materials; photovoltaics, new energy, etc., the market demand for silicone materials in the energy saving and environmental protection industry It will maintain medium-to-high-speed growth; ultra-high voltage and ultra-high voltage power grid construction, 3D printing, smart wearable devices and other emerging fields will be the market growth and breakthrough points of silicone materials in the future.
