Description of Blue tire molding silicone
Blue tire molding silicone, which is used for precision casting of tire mold and reproduction of gypsum tire molds.
Applications of Molding silicone rubber
Molding silicone could be mainly used for making concrete stones, precision molds, PU molds, cake molds, for life casting, fabric finishing, seal for electronic components and solar circuit board, trademark decoration. etc.
Features of Tire Molding Silicone Rubber:
567890o[p
Tire molding silicone rubber is used in pouring (wrapping) way to make molds, and is with the hardness of about 20 shore A. Thus it is with advantage of low viscosity, good fluidity, good operability, easy to release bubbles, excellent tensile and tear strength, easy for pouring, and what's more, it is in blue, thus it is very easy to distinct the delicate patterns of the tire molds.
Addition cure silicone rubber for tire mold making operation:
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 1:1/10:1 and stir part A and part B evenly in 2-3 minutes .
4.And get the mixture for vacuum-pumping for de-air the bubble in around 2-3 minutes . (If there is no vacuum machine, pls pour the mixture carefully and slowly down 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 a layer of release agent(detergent or soap water)
on your product.
7. Pour the vacuumed mixture into the model frame from the side of the mold frame .
Addition cure silicone rubber for tire mold making package:
If ratio is 1:1 :Packed in 20kg/pail + 20kg/pail and 200kg/pail + 200kg/pail.
If ratio is 10:1 :Packed in 20kg/pail + 2kg/pail and 200kg/pail + 20kg/pail.
