What is Silicone?


I.Silicone Rubber’s structure

What is the organic silicone rubber: The basic structure of the organic silicon products unit is composed of a silicon-oxygen link,  and the side chain is connected by various kinds of organic silicone atoms and other groups. Therefore, in the structure of the organic silicone products containing both "organic groups", and "inorganic" structure, the special composition and molecular structure to make it combines the characteristics of organic matter and inorganic matter functions in one. And compared to other polymer materials, the most outstanding performances of organic silicone products include:

(1) Heat resistance properties

Organic silicone products are based on a silicon (Si) 0 oxygen key chain structure, the bond energy of the C - C key is 82.6 kcal/mol, while the bond energy of the Si - 0 key is 121 kcal/mol, silicone products own thermal stability. Under high temperature (or radiation exposure) molecular bonds will not break down. Organic silicone is not only can resistant to high temperatures and low temperatures but it can also be used in a wide range of temperatures. Chemical properties and physical-mechanical properties, along with the temperature change are small.

(2) Weather resistance

The main chain of organic silicone products is - Si - 0, no double bonds exist, therefore silicone products are not easy to get UV and ozone decomposition. Organic silicon is better than other high polymer materials in the thermal stability of the irradiation resistance and weather resistance ability. In the natural environment, organic silicone can serve over several decades.

(3) Low surface tension and surface energy

The main chain of organic silicon is very smooth, the intermolecular force is much weaker than hydrocarbons, therefore, with low molecular weight hydrocarbons viscosity, silicone has small surface tension and surface energy but is strong in film forming ability. This kind of low surface tension and low surface energy is the main reason why silicone for various applications: hydrophobic, foam, foam stability, adhesion, lubrication, polishing, and other excellent performance.



II.The Common Application of Silicone Rubber

Silicone products can be widely used in many different areas, for now, there are many different kinds of products on the market and in the life of common silicone products, like silicone mobile phones, silicone keypads, silicone tableware, silicone purse, silicone accessories, etc., with silicone rubber as the main raw material processing system works, are called silicone products. Silicone is composed of a porous mass particle under appropriate dehydration of silicone acid. With an open porous structure, which can adsorb many substances, silicone is a kind of very good desiccant, adsorbent, and catalyst carrier.

Also because of its good electrical insulating properties, and in a wide temperature range and frequency range, the resistance value can be stable, silicone can also be seen in electrical components such as in the electronic industry. Now there are many watch straps for children that are made of silicone, which is soft and comfortable to wear, not easy to deformation.

Silicone gradually becomes a more and more popular alternative material to plastic for its environment-friendly and cost-effective nature. NEWTOP is a silicone parts manufacturer&custom silicone molding factory in China with over 15-year experience. We had manufactured many product cases since our foundation. The cases included silicone baby and mom care products, silicone kitchenware tools, silicone o-rings, silicone seals, silicone tubing, custom silicone molds, etc. Premium satisfaction is our mission and task.

What is Liquid Injection Moulding?

  I. What is liquid silicone rubber molding? Liquid silicone rubber (LSR) molding, sometimes called liquid injection molding (LIM), is a thermosetting process in which two compounds are mixed and then heat-cured using a platinum catalyst inside a mold to create flexible silicone parts. Low compression permanent deformation and the ability to resist extreme temperatures make LSR molded pieces durable and ideal for challenging applications. LSR elastomers offer superior optical clarity, durability, and design flexibility while operating over a wide temperature range (-50℃ to 250℃). LSR injection molding is suitable for manufacturing complex geometric shapes, and because of its design and mold flexibility, multiple functional components can be combined into a single part. LIM has considerable advantages in terms of product reliability and total tooling cost. II.How is LSR different from injection molding? LSR molding is very similar to the way traditional injection molded parts are ...

  Liquid silicone adhesive refers to a layer of liquid silicone coated on metal, rubber, plastic, and other materials. It uses some properties of liquid silicone itself to play a good hand feeling, aging resistance, good release, anti-slip, dustproof, waterproof, and sealing functions. The liquid silicone coating process generally includes three parts: bottom treatment, bottom coating, and liquid silicone. The following steps are detailed. Treatment of the bottom: The bottom surface of the liquid silicone should be treated well before the package. It is mainly to ensure that the surface of the coated rubber is smooth and flawless, so as not to crack the adhesive when the force is applied; In addition, it is necessary to test whether the surface of the adhesive is clean and whether there is no oil. If there is oil, it needs to be cleaned with xylene and other solvents. Primer: Generally liquid silicone is non-stick with other materials (except solid silicone), so the material at the...
