Company Profile
Shenzhen Zhihua Chemical Co.,Ltd. was established in 2008,is a science and technology Company which is concentrating on production, R&D, and sales of Chemical products, especially silicone rubber.
We are praised as the leading professional manufacturer of Mould Making Silicone Rubber, Addition Silicone Rubber ,Life Casting Silicone Rubber, Electronic Potting Compound, Pad Printing Silicone Rubber, and so on.
There has two main Series of best selling silicone rubber in our company. The DC-A Series Addition cure silicone rubber and The DC- C Series Condensation cure silicone rubber.
The DC-A Series Addition cure silicone rubber is mainly used for making molds of concrete stone, GRC, polyurethane products ; wax, candle decoration; rapid prototyping and tire molds; chocolate, candy and similar products' molding. and also can used for life casting.
The DC- C Series Condensation cure silicone rubber is used for making molds of concrete stone, GRC, gypsum decoration, plaster ornaments, fiberglass products, polyester decoration, unsaturated resin crafts, polyresin crafts, polyurethane, bronze, wax, candle, and similar products.
Both Series has different hardness from 0-50 shore A.small size product with detailed pattern we suggest your use low hardness such as 10-20A,for middle or large size product with pattern you can choose 25-35A, and for big size with little detail you can use 40-50 shore A hardness.
Our products are widely recognized and trusted by users and can meet continuously changing economic and social needs.
We are welcome to all the customers come to visit our factory and have a fruitful business relationship with our company.

Manufacturing Process
Step 1: prepare the original molds
Prepare an perfect original mold and clean it totally before operation.
＊Notes: Make sure your original molds and operation tool were cleaned up totally to avoid uncured problem .
Step 2: Take 100 G part A and 100 G part B (Or 100 G part A and 10 G part B) and mix them evenly.
＊Notes: Addition cure mold making silicon rubber is two parts flowing liquid, Pls 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 uncured problem.
2.Mix part A and part B evenly. Otherwise the silicon rubber will be partly solidified 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 silicone 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 or Brush operation
＊Notes:1. For simple pattern products we suggest use pouring operation way, which will be very easy to operate and demould. Pourable silicone require low viscosity which will be easy to flow smoothly and easy to de-air .
2.For delicate pattern products we suggest use brushing operation way, which can copy the pattern exactly. Brushable silicone require high viscosity which won’t be easy to flow away and easy to brush .
3. We suggest to set the silicone mold for another 12 hours after demould before you put it into a large production .
