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 .

ï¼Å 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. 

ï¼Å 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

ï¼Å Do not mix with liquid condensation silicone rubber or even the tool which used for condensation silicone 

ï¼Å Do not mix with organic matter which contains N, S, P organics and ionic compound like Sn, As,Hg, Ph,

ï¼Å Do not add any pigment or powder into the addition cure silicone rubber without any testing to prevent uncure problem
