Dust ring manufacturers tell the difference between silicone sealing ring and rubber sealing ring

1. Look at the burning situation of the two: there will be no fire when the silica gel is burning, and the incense ash is white, but when burning the rubber, you will find that the burning ash is black and the taste is particularly smelly. After vulcanization, silica gel has excellent resistance to high and low temperature -100~315 ℃, weather resistance, hydrophobicity, electrical insulation, physiological inertia and other characteristics, widely used in medical services, industrial and agricultural production and people's daily life. It is very important to be non-toxic and tasteless, such as baby silicone pacifiers and silicone breast augmentation fillers.

2. Rubber raw materials are divided into natural rubber and synthetic rubber. Natural rubber is made from latex collected by rubber trees and dried natural rubber. Moreover, natural rubber has excellent characteristics such as good elasticity and strong elongation; therefore, it is widely used in condom production, drainage hose, rain boots, etc. Synthetic rubber is rubber made from ingredients. Due to the high production cost, natural rubber will produce relatively low cost synthetic rubber. Synthetic rubber is mainly divided into chloroprene rubber, nitrile rubber, silicone rubber, fluorine rubber, polysulfide rubber, polyurethane rubber and so on.

3. Silicone sealing ring has good sealing performance, heat resistance and low temperature performance. At the same time, it is not easy to age for a long time, and it is non-toxic and harmless. After FDA, SGS and a series of quality certification. In the production process of silicone sealing ring, there are molding and bonding molding. The molded seal ring is directly molded and has no interface. In general, this type is used for sealing rings for rice cookers and pressure cookers.

Therefore, their definition and scope of application are different. Rubber is a general term, including many kinds, such as natural rubber, butadiene rubber, styrene butadiene rubber, propylene rubber, of course, including silicone rubber; silicone rubber is one of the outstanding varieties of rubber. Widely used in motor rubber seals, elevator rubber shock absorption accessories, rubber pipes, vehicle rubber accessories, engineering machinery rubber accessories, conveyor belts, nylon belts, reducer rubber seal accessories, flange pads, O-rings and other rubber and plastic products.
