A Brief Introduction to DOP and DOTP

The introductions of DOP and DOTP

Overview

Some people may ask what is DOP and what is DOTP. Do they have differences? What are their benefits and disadvantages of them? Let Huisu Qinye tell you what is DOP and DOTP. Also, we will make you know better about the difference between DOP and DOTP.

Dioctyl phthalate is referred to as dioctyl ester (DOP) - an organic ester compound and a commonly used plasticizer. Dioctyl phthalate is an important general-purpose plasticizer. It is mainly used in the processing of polyvinyl chloride resin, and can also be used in the processing of high polymers such as chemical fiber resin, acetic acid resin, ABS resin, and rubber. Paints, dyes, dispersants, etc.

General-purpose DOP: widely used in plastics, rubber, paints, emulsifiers, and other industries. PVC plasticized with it can be used to manufacture artificial leather, agricultural films, packaging materials, cables, etc.

Electrical DOP: In addition to all the properties of general-purpose DOP, it also has good electrical insulation properties, mainly used in the production of wires and electricity.

Food grade DOP: mainly used in the production of food packaging materials.

Medical grade DOP: mainly used for the production of medical and health products, such as disposable medical equipment and medical packaging materials.

DOTP

DOTP plasticizer is the other type of plasticizers, this product is an almost colorless low-viscosity liquid. Viscosity 63mPa.s (25°C), 5mPa.s (100°C), 410mPa.s (0°C). Freezing point -48°C. The boiling point is 383°C (0.1)MPa.s (0°C). The ignition point is 399°C. Scientific name: dioctyl terephthalate. Normally, we called it DOTP.

In addition to a large number of plasticizers used in cable materials and PVC, DOTP can also be used in the production of artificial leather films. In addition, it has excellent compatibility and can also be used as a plasticizer for acrylonitrile derivatives, polyvinyl butyral, nitrile rubber, nitrocellulose, etc.

1. Different advantages of DOP and DOTP

Compared with the commonly used dioctyl phthalate (DOP), dioctyl terephthalate(DOTP) has the advantages of heat resistance, cold resistance, non-volatile, anti-extraction, flexibility, and good electrical insulation properties. Excellent durability, soapy water resistance, and low-temperature softness.

2. Different applications of DOP and DOTP

Dioctyl phthalate(DOP) is an important general-purpose plasticizer. It is mainly used in the processing of polyvinyl chloride resin. Otherwise, it can also be used in the processing of high polymers such as chemical fiber resin, acetic acid resin, ABS resin, and rubber. Paints, dyes, dispersants, etc.

In addition to a large number of plasticizers used in cable materials and PVC, DOTP can also be used in the production of artificial leather films. In addition, DOTP has excellent compatibility. Moreover, DOTP can also be used as a plasticizer for acrylonitrile derivatives, polyvinyl butyral, nitrile rubber, nitrocellulose, etc. It can also be used as a plasticizer for synthetic rubber, paint additives, precision instrument lubricants, lubricant additives, and as a softener for paper.
