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

There is a difference 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 terms of price. The vulcanization principle of platinum vulcanizing agent is that in the presence of the catalyst Pt, the hydrogen-containing silicone oil and the vinyl double bond undergo a hydrosilylation reaction. Platinum vulcanizing agent is a two-component addition molding 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 using platinum vulcanizing agent:

1. Use platinum to add vulcanization, do not use silica gel containing hydrogen-containing silicone oil, otherwise it is easy to die during rubber mixing and easy to produce bubbles during molding;

2. After platinum A and B glue are mixed evenly, they need to be placed in a space where the temperature does not exceed 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 unripeness.

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