Role of plasticizer:

1. Increase the flexibility of polymers;

2. Reduce the glass transition temperature;

3. Reduce the surface hardness of polymers;

4. Reduce melt viscosity.

The use of environment-friendly plasticizers is an inevitable trend in the use of plasticizers. At present, plasticizers are still used very much, but as chemical substances, excessive use may also bring pressure on environmental protection. Why should we say this? As the use of plasticizer increases, the corresponding waste will also increase. Once the waste is piled up, some chemical reactions will occur, which will be beyond our control. But on the one hand, plasticizers play a very important role, so people have produced environment-friendly plasticizers to relieve the pressure of the environment.
