In recent years, the improvement of people's awareness of environmental protection has promoted the upgrading and improvement of the production process of plastic products. In the production process of plastic products, plasticizers are an indispensable part, which can increase the flexibility, ductility and durability of plastic products. DOTP and DOP as a common plasticizer, in the market concern, then what is the difference between them?

1. production raw material
DOTP, also known as epoxy undecyl phosphate triester, is made by the reaction of epoxy and acid anhydride, and after acid hydrolysis and ester exchange of a plasticizer. And DOP, known as octanoic acid dibutyl ester, is a plasticizer obtained by ester exchange of octanol and anhydride.

from the production of raw materials, DOTP using epoxy and acid anhydride reaction, and DOP using octanol and acid anhydride after ester exchange, it can be seen that the production of DOTP raw materials more environmentally friendly and sustainable, in line with modern environmental protection concept.

2. environmental protection
With the increasing awareness of environmental protection, the production of plastic products is also facing higher environmental protection requirements. In this regard, DOTP has a more significant advantage than DOP. As an environmentally friendly plasticizer, DOTP's production raw materials and production processes are more environmentally friendly, not only reducing environmental pollution in the production process, but also safer and more reliable in the use of plastic products.

In addition, DOTP will not release toxic substances in the degradation process, which will not cause harm to the environment and human health. DOP may release harmful substances in the process of production and use, which has a certain impact on the environment and human health.

In summary, DOTP has obvious advantages over DOP in terms of raw materials and environmental protection. In the production and application of plastic products, the choice of environmentally friendly plasticizers can better protect the environment and human health, which is the future development trend of the plastics industry.

in the selection of plasticizers, not only need to consider its plasticizing effect, but also consider its impact on the environment and health. Therefore, DOTP, as an environmentally friendly plasticizer, will be more widely used and promoted in the future. It is believed that with the development of the times, more and more plastic products will use environmentally friendly DOTP as a plasticizer to jointly promote the sustainable development of the plastics industry.
