1.Features of Silicon Rubber for Making molds: 1) Excellent performance2)High tear strength3) Resistance to high temperature4) Competitive price5) Samples are available 2.Instructions of Silicon Rubber for Making molds:Silicon Rubber for Making molds are generally named as two-part room temperature sulfurated silicone rubber, which features an exceptional fluidity and good operability. When mixed with 2-3% curing agent, they can still be operated within 30 minutes, but will be formed after 2-3 hours. With resistance to deformation, high temperature, acid and alkali, and expansion, silicon flexible molds are used for mold duplication and delicate mold making for poli crafts, resin crafts lighting and candle crafts.3.Main types of Silicon Rubber for Making molds: Model 638#Appearance whiteMixing proportion of curing agent(%) 2%Operating time ( hours ) 0.5Curing time( hours ) 2-4Hardness (shore A) 22-28 Viscosity (CS) 25000-30000Tensile-strength( kgf /cm2 ) ≥ 37Tear-strength (kgf /cm2 ) ≥ 28Elongation-break(%) ≥ 540Retractility(%) ≤ 0.25Packing (kg/pail ) 25, 200728# white, the usage for poly crafts, lighting and candles, molds in multiple pieces for large products.Model 728#Appearance whiteMixing proportion of curing agent(%) 2Operating time ( hours ) 0.5Curing time( hours ) 2-4Hardness (shore A) 25-30 Viscosity (CS) 25000-28000Tensile-strength( kgf /cm2 ) ≥ 35Tear-strength (kgf /cm2 ) ≥ 25Elongation-break(%) ≥ 470Retractility(%) ≤ 0.25Packing (kg/pail ) 25, 200788# white, the usage for poly crafts, lighting and candles, multiple piece molds for large product.Model 730#Appearance whiteMixing proportion of curing agent(%) 2Operating time ( hours ) 0.5Curing time( hours ) 2-4Hardness (shore A) 28-32Viscosity (CS) 28000-30000Tensile-strength ( kgf /cm2 ) ≥ 35Tear-strength (kgf /cm2 ) ≥ 20Elongation-break(%) ≥ 470Retractility(%) ≤ 0.3Packing (kg/pail ) 25, 200Any questions, please feel free to contact kelly:TEL: 086-755-89948019FAX: 086-755-89948030MOBILE:086-18690907219Website: www(dot)szrl(dot)netE-MAIL: kelly6in(at)gmail(dot)comSkype：kelly619106
