liquid silicone rubber for household 1) Basic model: LIM19XXA/B 2) Product Description SQUARE®Lim19XXA/B is high strength 2-part liquid silicone rubber suitable for injection molding processes,catalyzed by platinum. 3) Key Features Good rebound property Excellent thermal and cold stability(-60centigrade to 250centigrade) Low yellowing Outstanding resistance to ageing Meeting US FDA CFR21. Part .177.2600,EN14350.2 and EU RoHS standard 4) Application SQUARE®Lim19XXA/B is suitable for making kitchenwares. 5) Storage Correctly stored in its original closed container at room temperature (max 27centigrade). SQUARE®Lim19××A/B has a shelf life of 180 days. The ready to use LIM19××A/B should be kept tightly closed and used up within 7 days. 6) How to use Ready-to-use mixturescomponent 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 mixtureat the mixing ratio 1to1 is injected into the heated mould at the mould temperature of 140-160,the mixed silicone rubber will be vulcanized in a few seconds. 7) Packaging SQUARE®Lim19XXA/B is available in 20kgs pails or 200kgs drums. 8) Typical properties Property Standard UnitLIM1930A/B LIM1940A/BLIM1950A/BLIM1960A/BLIM1970A/BAppearance transparenttransparenttransparenttransparenttransparentViscosity [Pa.s]200300300500700Density DIN53 479A g/cm31.071.081.101.131.14Shore A hardness DIN53 305 ºA3040506070Tensile strength DIN53 504 S2 Mpa5.05.55.566Tear strength ASTM D624 Die B KN/m13.013.015.015.015.0Elongation at break DIN53504 S2 %380400400380300Compression set DIN53 517 22hrs at 175 %8.010.011.012.013.0Linear shrinkage JISK 6301 %2.02.02.02.02.0The pot-life of the mixture of two parts (closed vessel) at 20 is 5 days, increased temperature reduces the pot-life Mixing ratio of AB=11 9) Remarks These figures are for reference only, Please contact us for detail.
