China Platinum Cured Silicone Rubber for Tire Mold

Platinum cured silicone rubber for tire mold

Description of platinum cured silicone rubber
platinum cure silicone rubber is a kind of translucent liquid , generally named two-components silicone rubber with mixing in 1:1 .It's mainly suitable for tire molds making .
Advantage of platinum cure silicone rubber for tire mold
1)Non- shrinkage
2)high tensile and tear strength with high copy times
3) exceptional fluidity and good operability (mixing ratio at 1:1 )
4)high temperature resistant in 250 Centigrade

Operation instruction of platinum cure silicone rubber for tire mold
Step One: Take 100g of part A and 100g of part B and mix in 1:1 and mix the two part evenly.
Step Two: vacuum pumping
Without exception, this step takes less than 10 minutes.
Note: The time for vacuum-pumping should be less than 3-5 minutes ,otherwise, once the silicone rubber has cross-link reaction during vacuum pumping process, it will not be operated.
Step Three: Pouring the mixture into the frame with original mold slowly .
Shelf life for silicon rubber for mold making
12 months, when stored in a dry & cool place under the room temperature 25.
Packing for silicon rubber for mold making
20kg/drum for part A+ 20kg/drum for part B in one set
,200 kg/drum for part A+ 200kg/drum for part B in one set
