What is a platinum vulcanizing agent?

Platinum vulcanizing agent is also known as platinum water, A/B two-component, it is in the presence of catalyst, hydrogen-containing silicone oil and vinyl double bond undergo hydrosilylation reaction, so as to achieve the purpose of cross-linking and vulcanization, it needs It is used together with silicone raw materials to play the role of vulcanization. So how does it perform?

1. No new low molecular weight is produced, no peculiar smell;
2. The hygiene level conforms to FDA, SGS, LFGB and other certifications, and is more reliable than other similar products;
3. One vulcanization is completed;
4. Good dimensional stability and low compression rate;
5. Save time and electricity, improve production efficiency and reduce production costs;
6. The mechanical function has been greatly improved.

What is the difference between platinum vulcanizing agent and ordinary vulcanizing agent?

There are still some differences between platinum vulcanizing agent and ordinary vulcanizing agent. Platinum vulcanizing agent has many advantages, so it is many times more expensive than ordinary vulcanizing agent in price. The vulcanization principle of platinum vulcanizing agent is that in the presence of catalyst Pt, hydrogen-containing silicone oil and vinyl double bond undergo hydrosilylation reaction. Platinum vulcanizing agent is a two-component addition vulcanizing agent, which has the characteristics of low vulcanization temperature and fast vulcanization speed. Compared with the traditional peroxide vulcanization system, it has the advantages of environmental protection, high efficiency and odorless.

Precautions for vulcanization with platinum vulcanizing agent:

1. Use platinum for vulcanization, and do not use silica gel containing hydrogen-containing silicone oil, otherwise it will be easy to die during rubber mixing and bubbles will be generated during molding;
2. After the platinum A and B glues are evenly mixed with each other, they need to be placed in a space with a temperature not exceeding 25 °C, and used within 8 hours to prevent cross-linking at room temperature;
3. Avoid contact with substances containing nitrogen N, phosphorus P, sulfur S and heavy metals, otherwise it will cause immaturity.

The platinum vulcanizing agent and platinum water of the platinum series are still relatively sharp. Two-component platinum vulcanizing agent is used in the production of various food grades, such as extrusion of transparent silicone tubes, molded pacifiers, cake pan molds, etc. Production of silicone rubber with lower vulcanization temperatures.
