When it comes to sealing rings, kitchen utensils, appliances, and many other products in every household cannot do without sealing rings. However, there are various materials of sealing rings on the market, such as silicone sealing rings, rubber sealing rings, etc. Nowadays, the most commonly used one is silicone sealing rings. Although they are all sealing rings, there are still significant differences in their use and raw materials! So how to distinguish the difference between the two?

First, let's look at the combustion of both: when silicone burns, there will be no open flame and the smoke is white, but when burning rubber, you will find that the burned ash is black and has a particularly foul smell. After vulcanization, silicone has excellent resistance to high and low temperatures of -100~315 ℃, weather resistance, hydrophobicity, electrical insulation, physiological inertness, and other characteristics. It has been widely used in medical and health care, industrial and agricultural production, and people's daily lives. The most important thing is that it is non-toxic and odorless, as commonly used in baby silicone pacifiers and silicone breast augmentation fillers.

The raw materials for rubber are divided into two types: natural rubber and synthetic rubber. Natural rubber is a natural rubber material made from latex collected from rubber trees, which is solidified and dried. And natural rubber has excellent properties such as excellent elasticity and strong elongation; Therefore, it is widely used in condom production, drainage hoses, rain shoes, and so on; Synthetic rubber is made from chemical components, while natural rubber has a relatively high production cost, which is why low-cost synthetic rubber has emerged. Synthetic rubber is mainly divided into chloroprene rubber, nitrile rubber, silicone rubber, fluorine rubber, polysulfide rubber, polyurethane rubber, and so on.

Therefore, the definitions and scope of use of the two are different. Rubber is a general term that includes many types, such as natural rubber, butadiene rubber, styrene butadiene rubber, propylene rubber, and of course, silicone rubber; And silicone is one of the most prominent varieties in rubber, with a wide range of applications, and it is also the first among silicone production plants!
