There are many classification methods of silica gel, such as solid silica gel and liquid silica gel according to shape; high temperature vulcanized silicone rubber, low temperature vulcanized silica gel and room temperature vulcanized silica gel according to vulcanization temperature; Forming silicone, condensation type silicone, etc. Liquid silica gel, English is LIQUID SILICONE RUBBER, abbreviated as LSR. Its concept is not simply divided into shape according to the above classification method, it has a special designation, which refers to addition molding injection molding liquid silica gel. Equivalent to LIQUID INJECTION MOULDING SILICONE, abbreviated to LIM or LIMS.

The 1960s and 1970s were a period of rapid development of the rubber and plastics industry, and a large number of new plastics and rubber materials were developed and introduced to the market. In the 1970s, silica gel shifted from military use to civilian use, and the market expanded rapidly. Since the compression molding process of solid silicone has problems such as labor-intensive, low degree of automation, and high energy consumption, can silicone be injection molded like plastic? Since the late 1970s, internationally renowned silicone companies began to research liquid injection molding silicone. It mainly solves technical difficulties such as fluidity, physical and mechanical properties, safe operation time, and injection process. In the late 1980s, China began to develop liquid silica gel.

Since the late 1980s, liquid silicone has been industrially produced, and has expanded from a relatively narrow application field to more and more application fields. Today, liquid silicone has been used in automotive parts, electrical insulation, electronics, and food packaging. , medical equipment, health care, sports equipment, solar energy, optics, printers, military industry, etc. in a wide range of fields.

At the beginning of the 21st century, China began the industrial production of liquid silica gel. Compared with developed countries, it is about 10 years behind, but after more than 10 years of development, China has become a force that cannot be ignored in the production and consumption of liquid silica gel worldwide. It turned out that the liquid silicone technology was only mastered in a few international multinational companies and spread to emerging countries; from a few application fields to many fields, from a single product to a series of development; from technology-led market consumption to market-driven product research and development transformation; by Basic research is transformed into applied R&D.

The consumer market of liquid silicone has shifted from developed western countries to emerging markets represented by China. As China becomes the world's factory, more and more liquid silicone is processed into various parts in China and sold to the global market including China. . Since the global economic downturn caused by the U.S. subprime mortgage crisis in 2008, the demand for liquid silica gel has been greatly reduced, especially in the consumer goods market. Due to weak demand, the supply of liquid silicone rubber is relatively surplus. As a result, the world's famous liquid silicone rubber suppliers have uncharacteristically started a price war. They used to be in relatively backward countries. Now the situation is that the price war of liquid silicone rubber is in full swing around the world, which is very lively. The situation in China is even more tragic, even worse.

More efforts should be made in technological innovation to catch up with the pace of international advanced technological development. Only with excellent product quality can it be possible to win in the market. Digestion and absorption of knowledge is the first step, converting knowledge into technology is the second step, and finally providing products with excellent cost performance to customers is the key third step. Excellent enterprises, upstream and downstream should consider the combination of strong and strong, complement each other's advantages, strengthen the resistance to deal with fierce competition, put down the burden, activate the brain, strengthen the foundation and cultivate the original, positive reality, look to the future, not impetuous, and do things down-to-earth , in order to be invincible in the competition in the future.
