1. Applications of Printing Pads Making Silicone Rubber Material Pad printing silicone rubber is mainly use for printing irregular patterns of plastic toys, electroplating toys and trade makers . Pad printing silicone rubber as a carrier which transfer patterns on the steel plate to the toys products surface. 2. Features of Printing Pads Making Silicone Rubber Material a. resistance to deformation, high-temperature b. high printing times c. good aging resistance d. exceptional elasticity e. great printing effect 3. Operation Instructions of Printing Pads Making Silicone Rubber Material Pad printing silicone rubber is twocomponent silicone, part A is liquid silicon rubber, part B is catalyst. The usual mixture of silicone rubber and catalyst is 100: 2 or 100: 3. E.g. we take 100g of liquid silicon rubber and 2g-3g catalyst, mix them and pour it to your mold. A fter 2-4 hours, you will get a Pad printing silicone rubber 4.
