YJS-520 Shoe Sole Mold Making Liquid Silicone Rubber

1.Description YJS-525 is good for shoe sole molding products. They are widely used for manual mold making, shoes molds, plaster models, sole sampling, sand casting, etc. 2. Technical Datasheet Typical general characteristics Inspection Method Value Product data (Catalyzed A+B) YJS-525 Hardness Shore A 25±2 Mix Ratio A:B 100:2 Color / White Pot life 25 °C (77F) 30-40mins Curing time 25 °C (77F) 3-4 hours Mixed viscosity mPa.s 25000±1000 Tear-strength kg/cm 25±2 Tensile-strength M.pa 4.0±0.5 Elongation % 450±50 Shrinkage % ≤0.2% Note: This is a 100A:2B mix ratio product that must be measured by weight. The choosing of suitable hardness should be according to the size and pattern design of the products. If large products and therefore multiple-piece molds are needed by customers, silicone rubber with higher hardness will be required for the molds. Conversely, soft silicon is indispensable for molds with complicated pattern and delicate details. The amount of curing agent admixture depends on the actual need of customers. More will be added for speedy drying and fast release and less when otherwise. 3. FEATURES 1.Low viscosity 2.great flexibility 3.Extra low shrinkage 4.Chemical resistance 5.release properties 6.Easy to work with 4.High tear strength 5.Heat Resistance 6.various color is available 7.High reproduction rate 4.Appearance Part A: Silicone rubber is a white liquid Part B: Catalyst is a non-toxic and odorless liquid, white transparent color.
