High-temperature silica gel connecting wireIn addition to the characteristics of the material itself, there are also softeners used in the production process to increase the flexibility of the wire. So, in the production process, what are the main softeners commonly used by our high-temperature silica gel connection line manufacturers? What are their characteristics?
The first is transformer oil. This softener is the most commonly used high-temperature silica gel connecting wire softener. It is generally a light yellow liquid with characteristics of oxidation resistance and cold resistance. Together, it does not affect the electrical insulation.
The second is solid coumarone, which is in light yellow or brown solid state, soluble in chlorinated hydrocarbons, esters, ketones, nitrobenzene, aniline and other organic solvents and most fatty oils. It helps to disperse carbon black and improve the extrusion process function of rubber compound.
It can dissolve sulfur, make it uniform and loose, avoid scorching, and improve the physical and mechanical functions and aging resistance of vulcanizates. It plays a certain reinforcing role in styrene-butadiene, nitrile and neoprene rubber.
The third is industrial white wax, which is white and yellow. It is a crystal structure. It is used in the production process to lubricate the silicone rubber, easy to extrude, improve the appearance and other characteristics. Together, it can also improve the quality of high-temperature silica gel connecting wire, enhance the damage to the wire caused by ozone, water, UV, etc., and extend the service life.
There is also pine tar, a liquid softener, which is sticky and brown, but its disadvantage is not environmentally friendly. Slightly soluble in water, soluble in ethanol, ether, chloroform, acetone, glacial acetic acid, sodium hydroxide solution, etc. It helps the dispersing of the compounding agent in the glue, and has the effect of increasing the viscosity. It can improve the cold resistance of the high-temperature silica gel connecting wire, and is a universal softener.
