silicone rubber for tire mold making
Addition cure silicone rubber for tire mold making typical application:
Addition cure silicone rubber for tire mold making is primarily intended for tires making , and can be used for poly resin crafts, PU crafts, PU resin crafts ,gypsum crafts ,unsaturated resin crafts, lighting and candles crafts ,plastic toy , stationery gifts crafts industry,a large statue Buddha, furniture, furniture decorative materials, statues Buddha, artifacts copied, building decoration materials, large-scale cement mold, artificial fossils Factory, Europe component factory, simulation landscapes, animals and plants sculpture, sandstone crafts and so on.
Addition cure silicone rubber for tire mold making description:
Addition cure silicone rubber for tire mold making is white or red flowing liquid with general hardness of 22-50A°after curing. Molding silicon rubber is a kind elastic silicon rubber mold which features with resistance to deformation, high- temperature, acid-alkali and expansion as well as high reproduction times, good tensile strength, tear strength and elongation.
Addition cure silicone rubber for tire mold making feature:
-almost nil shrinkage
-high chemical resistance to aggressive components of some types of resins
-good tear strength (this feature ensures higher resistance to wearing and shearing)
-high degree of precision in reproduction
-high dimensional stability over time and non-deformability
-high resistance to high temperature and aging(resist -60 to 200°C)
-excellent non-stick effect
-food grade silicone (environmental,odorless and nontoxic)

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 notice:
What’s the limitations of silicone?
a. When the hardness of silicon rubber is lower than 15 shore A, the tension, the tear strength, the ageing resistance, acid and alkali-resistance of silicon rubber will reduce respectively.
b. When the hardness of silicon rubber is higher than 50 shore A, the tension and the tear strength of silicon rubber will reduce, and the solidified silicon mold will be easily broken.
Addition cure silicone rubber for tire mold making shelf life:
8-10 months when stored under 24°C in original unopened packages.
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.
