Skin Safe Liquid Silicone Rubber

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 .

＊Notes: 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. 

＊Notes: 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. What’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

＊Do not mix with liquid condensation silicone rubber or even the tool which used for condensation silicone 

＊Do not mix with organic matter which contains N, S, P organics and ionic compound like Sn, As,Hg, Ph,

＊Do not add any pigment or powder into the addition cure silicone rubber without any testing to prevent uncure problem
