Liquid Silicone Rubber (LSR) and Solid Silicone Rubber

Liquid Silicone Rubber (LSR) and Solid Silicone Rubber
                                                                                                                        ---- Five Comparisons
Silicone Rubber , liquid silicone rubber  and solid silicone rubber  included, is an elastomer compound for   liquid silicone rubber injection molding  or silicone rubber compression molding ,  which are widely used in automotive applications, food storage products, electronics, infants products and medical devices due to non-reactive, elongation, tear strength, resistance to extreme environments and temperatures, and so on .
 
Liquid Silicone Rubber and Solid Silicone Rubber can be divided according to physical forms. However, if they are made into finished product, it will be difficult to tell difference. Now, let’s make a comparison between Liquid Silicon rubber and solid silicone rubber.
 
Liquid Silicone Rubber and Solid Silicone Rubber-physical forms
LSR  ——  Liquid state with liquidity
Solid Silicone Rubber  ——  Solid state without liquidity
 
 
Liquid Silicone Rubber and Solid Silicone Rubber-applications
Liquid Silicone is food-grade and skin-friendly, which can contact food and human body directly. But its application is limited, mainly in infant series, kitchen wares and medical products.
Solid Silicone has a wider range of applications in daily necessities, silicone rubber accessories and automobile parts, etc.


 
Liquid Silicone Rubber and Solid Silicone Rubber-safety
Liquid Silicone Rubber is a kind of high transparent and safe food-grade material through closed batch charging forming, without adding vulcanizing agents during molding.
Solid Silicone Rubber is transparent and eco-friendly material through open mould batch charging forming, which needs to add vulcanizing agents to accelerate vulcanization molding.  
 
Liquid Silicone Rubber and Solid Silicone Rubber-forming method
Liquid Silicone Rubber is also Injection Molding Liquid Silicone Rubber (LSR) and the curing equipment is Injection molding machine. More simple technical process and higher-level automation, preciser product size and higher productivity are main advantages of Liquid Silicone.
1）More simple technical process and higher-level automation: Liquid silicone rubber injection molding is used for LSR, which offers high levels of automation. Don’t need workers for dosing, milling, blanking and placing material.
2）Preciser size: All manual procedures are replaced by machine, which improves the products precision.
3）Higher productivity: The mixture silicone rubber forms for several seconds under certain temperature.

Solid Silicone Rubber are solid pieces, which are mixed by mixing rolls, cut by cutting machine into the appropriate size and thickness of mould and product, then placed on silicone rubber compression molding, finally moulded by compression molding machine under certain temperature. Rubber compression molding need to be cleaned up.
        
 
Liquid Silicone Rubber products and Solid Silicone Rubber products
Liquid silicone products is high transparent and odorless, with injection gate.
Solid Silicone products is low transparent, with the odor of vulcanizing agent and without injection gate.
