Description of platinum cured silicone rubber
platinum cure silicone rubber is a kind of FDA grade silicone ,
generally named two-components silicone rubber with translucent
appearance, Part A and part B mixing in 1:1 .It’s suitable for
molds making application.
Applications of platinum cure silicone rubber
Platinum cure silicone rubber mainly used for making concrete
stones, wax molds, PU molds, resin molds, gypsum casting, candle
molding and chocolate , candy and any otherfood product molds making
Advantage of platinum cure silicone rubber
1)Non- shrinkage (less than 0.1% )
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 ofplatinum cure silicone rubber
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 .
