Detailed Product Description
 
This series are 2-part translucent liquid silicone rubber suitable for injection molding processes.
 
1) Basic model: LSR2009-40A/B, LSR2010-40A/B,LSR2000-40A/B
2) Product Description
This series are 2-part translucent liquid silicone rubber suitable for injection molding
    processes,catalyzed by platinum(LSR2009-40A/B is fast cured type).
3)Key Features
       Good rebound property
       Excellent thermal and cold stability(-60°C~250°C)
       Good fluidity,easy to be injected
       Stable shrinkage rate
       High tear strength
4) Application
The series are suitable for making lining of computer keyboard
5) Storage:
Correctly stored in its original closed container at room temperature (max 27°C). SQUARE@ LSR20**-40A/B has a shelf life of 180 days. The ready to use LSR20**-40A/B should be kept tightly closed, if it doesn’t , it will affect the shelf life. 
6)How to use
Ready-to-use mixtures(components A and B)are fed directly to injection molding machine from the original containers by means of a metering end mixing unit (called static mixer). The mixture(at the mixing ratio 1:1) is injected into the heated mould,the mixed silicone rubber will be vulcanized in a few seconds.
7) Packaging
      The product  is available in 20kgs pails or 200kgs drums
