As plastic additives, ortho benzene and DOP play important roles in the production process of plastic products. Although both belong to the category of plasticizers, there are some differences in their properties and uses

Phthalate, also known as phthalate, is one of the commonly used plasticizers. It has a good plasticizing effect, which can effectively reduce the processing temperature of plastic products, improve their flexibility and ductility. Phthalate is widely used in the production of plastics such as PVC, PE, and PS, which can improve the processing and physical properties of plastics. In addition, ortho benzene can also improve the low temperature resistance and weather resistance of plastic products

DOP, full name di 2-ethylhexenyl acetate, is another commonly used plasticizer. Compared with ortho benzene, DOP has better flexibility and ductility. It is a colorless and transparent liquid widely used as a plasticizer in plastic production. DOP is mainly used for the softening and toughening of plastic products, such as hoses, wires and cables, leather products, etc

The difference between ortho benzene and DOP is mainly reflected in the following aspects: 

1 Different properties: o-benzene is a solid substance, while DOP is a liquid substance. This means that when used in additive formulations, ortho benzene needs to undergo melting and dispersion treatment, while DOP can be directly added to liquid formulations

2. Different physical properties: ortho benzene has a better plasticizing effect in plastics, providing higher flexibility and ductility, and has a significant effect on increasing the toughness and cold resistance of plastics. And DOP has better flexibility and ductility, which can make the plastic surface smoother and increase the plasticity and processability of the plastic

3. Different application areas: ortho benzene is mainly used for plasticizing hard plastics, such as PVC pipes, wires and cables, etc. DOP is mainly used for toughening and softening treatment of soft plastics, such as PVC flooring, leather products, etc

In summary, although ortho benzene and DOP are both plastic additives, there are some differences in their properties, physical properties, and applicable fields. When choosing to use, we should choose appropriate additives based on specific needs and the properties of plastic products to achieve the best processing effect and product quality. I hope this article is helpful for you to understand the difference between ortho benzene and DOP.
