high tear strength tire molding silicon rubber
1 Brief Introduction to high tear strength tire molding silicon rubber:
tire molding silicone rubber is generally named two-components silicone rubber, Part A and part B. It features an exceptional fluidity and good operability. The mixing ratio is 1:1 (10:1),mainly be suitable for making molds application.
2 Characteristics of high tear strength tire molding silicon rubber:
*low shrinkage (less than 0.1% )
*high tensile and tear strength with high copy times
*easy for operation (mixing ratio at 1:1 /10:1)
*very good flow and easy for pouring operation
*Fast and non-shrink cure at room temperature which can be accelerated considerably by the application of heat

4 high tear strength tire molding silicon rubber Operation instruction
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 .
