Apply in the electrical industry Simethicone is used as insulation medium of temperature resistant, corona and arc resistant, corrosion resistant, moisture-proof, dust-proof in the motor, electrical appliances, electronic instruments.
Currently, it is also used as impregnant of transformers, capacitors, television's scanning transformers. In a variety of precision machinery, equipment and instrumentation, it is used for liquid quakeproof, damping material. The shock elimination resistant of simethicone was little affected by temperature, so it commonly used on the occasions of strong mechanical vibration and larger temperature changes environment, such as the aircraft, automobile instrument. It is used in shakeproof, damping, stabilize meter reading, also can be as liquid spring for aircraft landing device.
As defoamers and release agents
Simethicone has small surface tension, and does not dissolve in water, in animal and vegetable oils and high boiling mineral oils, it has good chemical stability, and non-toxic. It has been widely used as defoamers in petroleum, chemical, medical, pharmaceutical, food processing, textile, printing and dyeing, paper and other industries, just add 10-100PPM silicone oil can be achieved a good defoaming effect. Due to simethicone without stickness with rubber, plastic, metal, etc., it also as a release agent in all kinds of rubber, plastics molding, used for precision casting. Used it as mold release agent not only convenience, but also make the product surface clean, smooth, texture clear.
For insulation, dustproof, moldproof coating
Coated simethicone on the glass, ceramic surface, and heated treatment at 250-300, can form a layer of semi-permanent waterproof, mildew resistant and insulating film. Used it to treat insulating device can increase the insulation performance of the device; treated optical instruments can prevent lenses and prisms go mouldy; treated medicine bottle can extend the shelf life of drugs and make preparations do not suffer damage because of sticking to the wall; handling the film's surface, it can act as a lubricant to reduce friction and prolong film life.
As lubricant, additives
Simethicone suitable for making rubber, plastic bearings, gear lubricants, but methyl silicone lubricating performance is not very well at room temperature, so under normal circumstances, it is not recommended as a lubricant between the metal at room temperature. Simethicone can be used as additives for many materials, such as paint lightening agent, added a small amount of silicone oil to the paint, can make the paint do not float package, do not wrinkle to improve the film's brightness; added a small amount of silicone oil to the ink, can be improved printing quality; added a small amount of silicone oil to the polishing oil (such as automotive coatings), can increase the luster, protect the film, and have a good waterproof effect.
The application in health care
Simethicone not only without aquatic toxicity to humans, but also can not decomposed by body fluids, so in the medical and health services, it also has been widely used. Make use of its defoaming effect can be made of Oral Gastrointestinal dimethicone tablets, pulmonary edema foaming aerosol, etc. Adding silicone oil in creams, can improve the ability of drugs penetrate the skin, improve efficacy. Some plaster based on silicone oil has a good effect on burns, dermatitis, bedsores, etc.
Other aspects
Simethicone also has many applications in other areas. Such as: use of its high flash point, odorless, colorless, transparent, and non-toxic to humans and other characteristics, as oil bath or thermostat heat carrier in the iron and steel, glass, ceramics and other industrial and scientific research. Use of its anti-shear properties, can be hydraulic oil especially aviation hydraulic oil. Handling rayon with it can eliminate static electricity, improve the quality of rayon. As cosmetics raw materials can increase the skin's moisture and protective effect and so on.

The application of tungsten in various industries
Steel Industry Most of tungsten applied in the production of special steels. The widely used high-speed steel was containing 9-24% of tungsten, 3.8-4.6% of chromium, 1-5% of vanadium, 4-7% of cobalt, 0.7-1.5% of carbon.
Magic effects of coconut oil
According to records, coconut oil can be regarded as the nobility of skin care plant extracts. It was rich in exotic tension of tropical plants, which can enhance the contractile force of the pores, perfectly beautify and nourish the skin.
The Evolution and Impact of Abamectin and Emamectin Benzoate in Pest Control
Abamectin and its derivative, emamectin benzoate, have emerged as pivotal substances in the realm of pest control, offering a broad-spectrum efficacy against various pests while maintaining a favorable environmental profile. As the agricultural industry continues to evolve, these compounds have adapted to meet the growing challenges of pest resistance, expanding their market applications and maintaining cost-effectiveness despite rising production costs.
