When it comes to sealing rings, kitchen utensils, electrical appliances, and many other products in every household are inseparable from sealing rings, but there are various materials of sealing rings on the market, such as silicone sealing rings, rubber sealing rings, etc., which are commonly used now. Most of them are silicone sealing rings. It is said that they are all sealing rings, but they are still very different in terms of use and raw materials! So how to tell the difference between the two?
First look at the combustion of the two: there is no open flame and the soot is white when the silicone is burned, but when the rubber is burned, you will find that the burning ashes are black and smell very bad. After vulcanization, silica gel has excellent high and low temperature resistance -100~315 ℃, weather resistance, water repellency, electrical insulation, physiological inertia and other characteristics, and has been widely used in medical and health, industrial and agricultural production and people's daily life. The most important thing is that it is non-toxic and odorless, such as baby silicone pacifiers and silicone breast implant fillers.
The raw materials of rubber are divided into two types: natural rubber and synthetic rubber. Natural rubber is a natural rubber product made from latex collected from rubber trees, after coagulation and drying. And natural rubber has excellent properties such as excellent elasticity and strong elongation; therefore, it is widely used in condom production, drainage hoses, rain boots, etc.;
Synthetic rubber is a rubber made of chemical components. Natural rubber has a relatively high production cost, so synthetic rubber with relatively low cost was born. Synthetic rubber is mainly divided into: neoprene, nitrile rubber, silicone rubber, fluorine rubber, polysulfide rubber, polyurethane rubber and so on.
Therefore, the definition and scope of use of the two are different. Rubber is a general term that includes many types, such as natural rubber, cis-butadiene rubber, styrene-butadiene rubber, propylene rubber, and of course silicone rubber; and silicone rubber is one of the most prominent varieties of rubber, and its application range is also relatively Guang is also the first in the silicone production factory!
