Product Name: Translucent RTV Silicone Rubber for Rapid Prototyping Model NO.: HY-E640 silicone for rapid prototyping Form: Liquid Rubber Appearance: Liquid Material: Silicone Rubber Raw Material: Natural Rubber Color: Translucent Certifications: RoHS.SGS ISO9001:2000 Brand: Hong Ye Silicone Rubber Application: Silicone for Tyre Mold Casting MOQ: 200 Kgs Shelf Life: 1 Year Port: Shenzhen Sample: Available Payment: T/T, L/C Trademark: Hong Ye Silicone Rubber Transport Package: 20kg/Drum 200kg/Drum Specification: RoHS, ISO-2001, SGS Origin: Shenzhen HS Code: 39100000 Product Description Translucent RTV silicone rubber for rapid prototypingDescriptions of addition cure silicone :addition tyre molding silicone is generally named two-components siliconerubber, Part Aand part B. It features an exceptional fluidity and good operability. Themixing ratio is 1:1,mainly be suitable for making molds application.Applications of addition cure silicone :E-640 addition tyre molding silicone could be mainly used for making concreteStones mold ,jewelry mold ,statue mold, artificial craft mold, wax molds, PU molds, resin molds, gypsum casting, candle molding and chocolate ,candy and any other FDA food product mold making,prototyping etc.Advantage* low shrinkage (less than 0.1% )*high tensile and tear strength with high copy times*easy for operation (mixing ratio at 1:1)*good fluidity easy for pouring operation (in round 10000 cps )Technique Data Sheet of E-625 addition cure siliconeProductE-640AppearanceTranslucentHardness(shore A)40±2Mix ratio(A:B)1:1Viscocity(mPa.s)10000±2000Tensile strength (kgf/cm2)50±5Tear-strength (kN/m)18±2Elongation(%)450±50Pot life/working time (mins)30-40Curing time/setting time (hrs)3-4hrs(25°C)110-20mins(60°C)Shrinkage rate (%)≤0.1(Note: the hardness ,color, curing time and operation time is adjustable)Operation instruction of HY-E Series molding silicone:1. Pls clear the model and tool totally before operation to prevent cure inhibition.2.Weigh the two part correctly by electronic weight in two separate container .3. Mixing the two part in 1:1 and stir part Aand part Bevenly in 2-3 minutes .4.And get the mixture for vacuum-pumping for de-air the bubble in around 2-3minutes .(If there is no vacuum machine, pls pour the mixture carefully and slowlydown the side of the mold frame so that less bubbles caused)5. Enclose the product (the original model) with four plastic plates or wooden plates.6. Clean your products and brush alayer of release agent(detergent or soap water) onyour product.7. Pour the vacuumed mixture into the model frame from the side of the mold frame .Notice: As our E-series silicone is addition cure tyre silicone ,which is very easy to causecure inhibition ,so pls do remember thoroughly clean the model and tool beforeoperation .Besides ,pls avoid the liquid E-series silicone contact or mix with thefollowing material ,otherwise the silicone won't be cured :1. Liquid condensation silicone (condensation silicone not completely cured or organictin compounds )2 .Sulphur, sulfide and sulfur rubber materials.3. Amine compounds as well as contains the amine materials.4 .Pewter solder flux.SHELF LIFE:8-10 months when stored under 24°C in original unopened packages.PACKAGE: Packed in 20kg/pail+20kg/pail, 200kg/pail+200kg/pail.More information ,pls feel free to contact Ms Lydia:Mobile :86-18988789546
