What is the difference between silicone and rubber

Time: 2021-03-18 View: 218

Nowadays, silicone and rubber products are widely used in our lives. Different ingredients make different products. Today, let’s take a closer look at the differences between the two. First of all, the two components are different. Silica gel is a highly active absorbent material, the main component is silica, while rubber is a highly elastic polymer material, the main component is latex, which is produced in rubber trees; secondly, the characteristics of silica gel are different, and the adsorption of silica gel is good. It can absorb a variety of substances, and rubber has high elasticity, can change different shapes, and has high tear strength and elongation. In addition, silica gel is chemically stable, insoluble in water, non-flammable, and has high heat resistance, while rubber is flammable , It is easy to soften and melt in high temperature environment.

Features and uses of silica gel

Silica gel is an amorphous substance with stable chemical properties, non-toxic and harmless, no allergic reaction, insoluble in water and any solvents, and contact with other tissues will not change its original elasticity and softness. It is not easy to melt under high temperature environment, which will lay the foundation for future use. For example, the prosthesis used in rhinoplasty surgery is silicone, which is not easy to deform, and the silicone used in breast augmentation surgery is not easy to change its softness. Generally speaking, the biggest advantage of silica gel is good adsorption, good heat resistance, and insulation. It is precisely because of these characteristics that it is used as a desiccant and adsorbent. High heat resistance, no performance change in high temperature environment, so it is used as a sealing ring for electrical appliances, and it is non-toxic and tasteless when heated.

Characteristics and uses of rubber

The components of natural rubber are mainly derived from the latex produced by the rubber tree, which is processed into synthetic rubber. The biggest feature of rubber is its plasticity and high elasticity. It can change the state of objects at room temperature. Because of its high elasticity, it also has the function of buffering and damping. This can be used to prevent noise and reduce vibration. It is generally used to make shock absorbers, mobile phone holders, and so on. Rubber is mainly used, such as rain boots, warm water bags, elastic bands, etc. in our lives. All car tires that we can see everywhere are made of rubber, because rubber has good plasticity and elasticity. After the tire is deformed, it can be It recovers quickly and has abrasion resistance. It can also reduce vibration during operation. Rubber is very useful in our lives. There are also recent hot latex pillow mattresses. They are all due to natural rubber. Latex mattresses are not. It collapses like ordinary mattresses because of its high elasticity. In short, rubber and silicone are all over our lives
