In recent years, the increasing awareness of environmental protection has promoted the upgrading and improvement of production processes for 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 common plasticizers, have received much attention in the market. So what are the differences between them

1、 The production raw material 

DOTP, also known as epoxy undecylphosphate triester, is a plasticizer obtained by the reaction of epoxy resin and anhydride, and after acid hydrolysis and ester exchange. DOP, also known as dibutyl octanoate, is a plasticizer obtained by ester exchange between octanol and anhydride

From the perspective of production raw materials, DOTP is obtained by reacting epoxy resin and anhydride, while DOP is obtained through ester exchange of octanol and anhydride. It can be seen that the production raw materials of DOTP are more environmentally friendly and sustainable, in line with modern environmental protection concepts

2、 With the increasing awareness of environmental protection among people, the production of plastic products also faces higher environmental requirements. At this point, DOTP has a more significant advantage than DOP. DOTP, as an environmentally friendly plasticizer, has more environmentally friendly raw materials and production processes. It not only reduces environmental pollution during the production process, but also makes the use of plastic products safer and more reliable

In addition, DOTP does not release toxic substances during the degradation process, which poses no harm to the environment and human health. DOP may release harmful substances during production and use, which can have certain impacts on the environment and human health

In summary, DOTP has significant advantages over DOP in terms of raw material production and environmental friendliness. In the production and application of plastic products, choosing environmentally friendly plasticizers can better protect the environment and human health, which is the trend of future plastic industry development

When selecting plasticizers, it is not only necessary to consider their plasticizing effect, but also their impact on the environment and health. Therefore, as an environmentally friendly plasticizer, DOTP will be widely used and promoted in the future. I believe that with the development of the times, more and more plastic products will use environmentally friendly DOTP as a plasticizer, jointly promoting the sustainable development of the plastic industry.
