Description of insole silicone rubber :
It is a two-component addition organic silicone (platinum catalyst ) which can be cured at room temperature and also can be heat cured.It is colorless or skin-colored oily liquid and becomes soft elastic material after vulcanization, can be used for making soft silicone rubber material.
Feature of insole silicone rubber :
1.FDA & ROHS certificate.
2.No limitation with product thickness .Can do deep curing .
3.High temperature resistance (can reach 0~250 degrees ) ,acid and alkali-resistance and aging resistance
4.Light viscosity and good flowability .easy for pouring operation .
5.Can be cured both at room temperature or be heated
6.Low shrinkage .Not releasing low molecular during cross-linking process .So the volume is constant .The shrinkage rate is less than 0.1%.
7.Favorable tensile and tear strength
8.High temperature resistance ,acid and alkali-resistance and aging resistance
9.High duplication times .aging -resistance
10.Tasteless.no flammable,safe and reliable
11.Customize as you need
Operation Instruction for platinum cure liquid silicone rubber for insole
Step 1: Prepare the molds
Prepare an perfect mold and clean it totally before operation .
ï¼ŠNotes: Make sure your molds and operation tool cleaned up totally to avoid uncure problem .
Step 2: Mix part A and part B evenly
Take 100 G part A and 100 G part B and mix them evenly.
ï¼ŠNotes: Addition cure mold making silicone rubber is two parts flowing liquid, Please follow the step strictly:
1. Weigh the two part exactly by electronic weight.
If any part not in exactly weight , it may cause changing of hardness , or even cause uncure problem.
2. Mix part A and part B evenly.
Otherwise the silicone rubber will be partly cured and this will give birth to difficulties in your final operation. Whatâ€™s more, the finished molds will meet a short life. All of these will cause a waste of silicon rubber.
Step 3: Vacuum pumping
Without exception, this step takes less than 10 minutes. Otherwise, it will cause cross linking reaction, and no more further steps will be available.
Step 4: Pouring casting
Clean your molds and brush a layer of release agent (detergent or soap water )on your molds .Pouring the vacuumed mixture silicone on your molds.
Warm tips :
As addition cure silicone is a kind of platinum cure system, which will be easy to cause uncure problem, so kindly follow the tips below
ï¼ŠDo not mix with liquid condensation silicone rubber or even the tool which used for condensation silicone
ï¼ŠDo not mix with organic matter which contains N, S, P organics and ionic compound like Sn, As,Hg, Ph,
ï¼ŠDo not add any pigment or powder into the addition cure silicone rubber without any testing to prevent uncure problem
