Silicone rubber for goggles 1) Basic modelLIM39XXAG/BG2) Product Description SQUARE® LIM39XXAG/BG is high transparence,high strength and high tear strength 2-part liquid silicone rubber,suitable for injection molding processes,catalyzed by platinum3) Key Features High transparence High tear strength(≥35N/mm) Good rebound property Excellent thermal and cold stability(-60centigrade 250centigrade) Low yellowing Outstanding resistance to ageing Meet US FDA CFR 21.Part.177.2600 and EN14350.2 and 4.9 of volatile compound testing standard and Europe RoHS stardard. The safe operating period is 5days under airproof condition and 20,after mixing component A and B. The safe operating period will decrease with the increasing of the temperature.4) Applications Goggles and other products contacted with food5) Storage Correctly stored in its original closed container at room temperature (max 27centigrade). SQUARE® LIM39XXAG/BG has a shelf life of 360 days. The ready to use LIM39XXAG/BG should be kept tightly closed, if it doesnt , it will affect the shelf life. 6) How to use Ready-to-use mixturescomponent A and Bare 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 160-200,the mixed silicone rubber will be vulcanized in a few seconds.7) Packaging SQUARE® LIM39XXAG/BG is available in 20kgs pails or 200kgs drums.8) Typical propertiesProperty Test method UnitLIM3920LIM3930LIM3940LIM3950LIM3960LIM3970Appearance Transparent ,noimpurity Transparent Transparent Transparent Transparent Transparent Viscosity [mPa.s]700,000400,000600,000700,000700,000800,000Density DIN53 479A g/cm31.081.071.081.101.121.14Shore A hardness DIN53 305 ºA203040506070Tensile strength DIN53 504 S2 n/mm27.08.07.58.57.07.0Tear strength ASTM D624 Die B KN/m152530323528Elongation at break DIN53504 S2 %880400450500400320Compression set DIN53 517 22hrs at 175 %242525252525Linear shrinkage rate JISK 6301 %2.42.52.02.02.02.4 9) Remarks These figures are for reference only, Please contact us for detail
