Platinum Silicone Rubber Molding, Addition Cure Mould Making Liquid Silicone

Product DescriptionDescription ofPlatinum Silicone Rubber Molding
Platinum silicone rubbber molding is the a kind of room temperaturevulcanized polymer products with two parts. But also, it can be cured faster in higher temperature.



Features of platinum silicone rubber molding
• 1:1 mixing ratio, easy for operation by both hands and machine
• Large harndess scale, from 20 shore oo to 60 shore A
• favorable temperature resistance, -60~250℃
• Low shrinkage,for low molecular weight won't be released out in the process of cross-linking reaction, so the volume would be the same and nearly no thrinkage
• The curing wont be impacted by the products' deepth and it can be solidified in deepth
• Food grade, non-toxic and tasteless, with FDA and REACH approved
• High tensile&tear strength, high duplication times
• Favorable viscosity, good fluidity, easy infusion

1. Measuring & Mixing:before you begin, pre-mix Part A and Part B separately. After dispensing required amounts of Parts A and B into mixing container (1A:1B by weight or by volume), mix thoroughly making sure that you scrape the sides and bottom of the mixing container several times
2. Vacuum Degassing: After mixing parts A and B, vacuum material for 2-3 minutes at vacuum box, making sure that you leave enough room in container for product expansion.
3. Pouring : brushing or injection or casting the completion of the deair bubble in addition to the silicone into the mold (before pouring, first cast in the mold detergent or mold release agent that is better demolding.)
4. Curing: to complete the above steps, the silicone to cure for 2-12 hours fully cured depends on room temperature ; if heating 80-120 centigrade, can be completely cured within a few minutes.
5. Tips: This product will not cure against surfaces containing sulfur, tin, even when sealed.If you are not sure if your clay contains sulfur, do a small compatibility test before using for an important project.
Packing & DeliveryGernal package of platinum cure silicone rubber
The mixing ratio of the platinum cure/additional silicone rubber is 1:1, so the part a and part b would be half.Packed into pallets to protect the goods
