Silicone is also known as “silicone acid gel”. It is a highly active adsorbent material. It is an amorphous material with a chemical molecular formula of mSiO2•nH2O. Silicone does not react with any substance except strong alkali and hydrofluoric acid. Insoluble in water and any solvent, non-toxic, tasteless and chemically stable. The chemical composition and physical structure of silicone determine that it can’t be replace by other similar materials : high adsorption performance, good thermal stability, chemical stability, and high mechanical strength.
liquid silicone and solid silicone
Generally, according to the production process, the products made of silicone can be divided into two types, liquid silicone and solid silicone. Liquid silicone is mainly used for injection molding and processing of silicone products. It is generally common in medical products and not use in daily life. Solid silicone has been widely used. Most of the common ones we use in daily life are solid Silicone.
Why silicone product become more and more popular?
Due to its stable performance, environmentally friendly and non-toxic, silicone is almost 100% tested by the FDA. It is favored by a large number of consumers. Its varied appearance and bright colors make it gradually defeat the plastic in the market. The revolution of “silicone replace plastic “has grown rapidly over the past decade, with market growth rates breaking through more than 30% annually.
Now we will talk about the characteristics of excellent silicone products, certainly, we mainly discuss the products that are common in daily life.
Good temperature resistance.
The temperature resistance includes resist the high temperature and low temperature, the silicone material is based on silicon-oxygen (Si-O) bond, and the bond energy of C-C bond is 82.6 kcal/g. The bond of the molecule and the Si-O bond is 121 kcal/mol in silicone, so the thermal stability of the silicone product is high, and the chemical bond of the molecule at high temperature (or radiation irradiation) does not break or decompose. Good quality silicone products can reach a temperature range of up to 240 degrees Celsius and a minimum of -40 degrees Celsius. In this range, the silicone will not be burned or frozen.
Silicone product surface tension is weak, surface energy is small, film forming ability is strong. This make silicone excellent performance. Silicone products are a kind of waterproof product. There is no change under the water Therefore, our common silicone kitchen cleaning work is very simple. We only need the same cleaning method as ordinary porcelain or iron kitchen utensils, and don’t worry about it crush or break.
Stable performance and long service life.
The chemical properties of the silicone material are very stable. Except for strong alkali and hydrofluoric acid, it does not react with any substance. Therefore, the silicone product generally has a long service life and is very durable. Compared with other products, The entire life cycle is more cost effective.
The hardness of silicone products can be from 0 to 70 degrees of Shore, which is a very soft hardness. Our common silicone baby pacifier is generally 40 Shore hard, which means we can produce some softer daily necessities, these are more gentle and delicate, and can be folded to save storage space.
Multiple color selection.
Silicone products are added to the components of color master batch and vulcanizing agent during production, and the color of the final product can be adjusted at will. When we customize the silicone product, if we know the Pantone color NO. The silicone manufacturer can make the color as customer’s need.
Environmentally friendly and non-toxic.
Silicone products are very environmentally friendly and non-toxic. From the refining of raw materials, to the molding of products, to the final destruction, they will not produce toxic and harmful substances, and the raw materials of silicone products can be recycled, the waste FDA-level Products can be recycled into industrial products which has a low quality requirements.
