how to make pad rubber

1.Mixing

Pouring mixing emulsion with silicon rubber and silicon oil as 100:20-50 percent into a clean plastic cup. Beat up it  uniformity with a beating machine.

2.Cleaning

Cleaning the plastic pad module and put it on the table.

3.Harding

Adding 3-5 gram harder to mix emulsion and put in a vacuum glass cover of motor machine. Start the machine for 2-4 minutes till the air in the  mixing emulsions completely removed.

4.Pouring & Covering

Taking out mixing emulsion and pouring into pad module. Cover a wooden plate on it.

5. Solidifying

Solidification speed is related with the environment temperature, higher temperature,faster solidification speed. Otherwise, in order to expedite solidification speed, please put more  hardener into mixing emulsion.

6.Optimizing Hardness

Complete solidification requires 2-5 hours. Adjust the percentage of silicon oil can adjust the the hardness of rubber pad. Less percentage of silicon oil will produce a harder pad. When you increase the percentage of silicon pad, please add

corresponding percentage of hardener. But, too much percentage of silicon oil will affect pad quality negatively.
