Global Liquid Silicone Rubber (LSR) Market 2016 Industry Trends, Analysis & Forecast 2022Chapters1 Industry Overview of Liquid Silicone Rubber (LSR)1.1 Definition and Specifications of Liquid Silicone Rubber (LSR)1.1.1 Definition of Liquid Silicone Rubber (LSR)Liquid silicone rubber (LSR) is a high purity platinum-cure silicone. LSR is well suited for injection molding owing to its excellent liquidity. Its also very ideal for complex molds since it easily fits in the most complex parts of any mold.Liquid silicone rubbers (LSR) are characterized by a low viscosity compared to solid silicone rubbers (HTV). Liquid silicone rubbers are pumping able two-part compounds that are delivered ready to use. They are vulcanized by addition curing. Component A contains a Pt catalyst and component B a SiH-functional polysiloxane as curing agent. Compared to peroxide curing, liquid silicone rubbers do not release any curing byproducts.Liquid silicone rubbers (LSR) offer a wide range of applications, from the automotive industry, mechanical and process engineering, through electrical applications, the transmission and distribution industry, through to construction, foods, health care and the medical sector.LSR has two components as shown below. Once the two components are mixed, it will then start to cure very slowly.Table Two Components of Liquid Silicone Rubber (LSR)ComponentsContentsPart AVinyl polymerFillerPt-cat.Part BVinyl polymerFillerInhibitorCross-linkerSource: KCC Silicone, QYR Chemical & Material Research Center, Oct 2016Figure Picture of Liquid Silicone Rubber (LSR)Source: Public Information, QYR Chemical & Material Research Center, Oct 20161.1.2 Specifications of Liquid Silicone Rubber (LSR)There are several kinds of silicone rubber and among them is LSR.

During the late 1970s, LSR two component systems have quickly increased in popularity over the past four decades due to their advantages over Gum Silicone Rubbers. Not only are faster cycle times and fleshless molding possible, but all secondary equipment is contained near the molding press and there is no need to mill or process the material in any way prior to use. LSR is also popular due to its ability to compete with typical thermoplastic elastomers: similar production rates can be achieved and LSR utilize slightly modified thermoplastic molding equipment, allowing for minimal initial capital investment.The liquid silicone rubber (LSR) industry concentration is relatively high. The global liquid silicone rubber (LSR) industrys top ten producers were around accounted for 69% of industry production in 2015 with facilities located around the world. The global liquid silicone rubber (LSR) production had reached to 65.3 K Tonnes in 2015.The biggest global liquid silicone rubber (LSR) companies in the world are the Dow Corning, Wacker Chemicals, Momentive, ShinEtsu, KCC Corporation, Laur Silicone, Tianci Materials, Guangdong Polysil, Shenzhen SQUARE Silicone, BlueStar Xinghuo, Wynca, Jiangsu Tianchen and Dongguan New Orient Technology.In recent years, some Chinese enterprises begun enter the industry. The demand of Chinas market has maintained a rapid growth.Table Industry News List of Liquid Silicone Rubber (LSR)2 Manufacturing Cost Structure Analysis of Liquid Silicone Rubber (LSR)2.1 Raw Material Suppliers and Price Analysis of Liquid Silicone Rubber (LSR) As mentioned in the first chapter, the materials of liquid silicone rubber (LSR) include cyclosiloxane, catalyst, silicone resin and silica etc. In the manufacturing process, the most important raw material is the dimethyl cyclosiloxane (DMC). The following is the detailed introduction of the DMC.2.1.1 Silicone MonomerFigure Picture of Dimethyl Cyclosiloxane (DMC) Source: Public Information, QYR Chemical & Material Research Center, Oct 2016In recent years, the production capacity of silicone monomers (except especially specified ones, here mainly refer to methyl chlorosilane monomers) has grown quickly in China.In 2015, the Chinese silicone market as a whole went downward among volatility but the market supply was ample. In the first half of the year, some previously discontinued silicone monomer plants restarted production, new capacity began to release, and the overall operating rate of silicone monomer plants rose slightly. Discontinuation costs and operation profits become major considerations of the enterprises. It is expected that in 2015, Chinas annual silicone monomer output will reach about 1.6Mt, hitting a new high in recent years.Silicone monomers are a type of important chemical raw materials, mainly used in the production of silicone rubber, silicone oil and silicone resins. In 2014, the consumption of silicone monomers (converted to 100% polysiloxane; the same hereinafter) was 715K Tonne in China, increasing by 7 K Tonne from a year ago or up 1.0% year on year.In 2014, the whole Chinese silicone monomer market showed a concave trend.
