[Chemical Knowledge]：Glycol polyester: Explore the difference between polyester grade and industrial grade

Read： 808 Time：18months ago Source：Transform the World with Simplicity

Glycol polyester is an important chemical raw material, which is widely used in different fields. Polyester grade and industrial grade are the two common specifications, which are different in nature and use.

From the perspective of raw materials and production processes, there are certain differences between polyester grade and industrial grade glycol polyester. Polyester grade ethylene glycol polyester usually uses high-purity raw materials, and strictly controls the production process to ensure the purity and quality of the product. The industrial grade glycol polyester is relatively simple and extensive, mainly to meet the needs of general industrial production.

in performance and use, polyester grade and industrial grade glycol polyester is also different. Polyester-grade ethylene glycol polyester usually has high purity and good thermal stability, and is suitable for high-demand material processing and special industry applications, such as medicine, food, etc., while industrial-grade ethylene glycol polyester is widely used in general industrial fields such as plastic products, coatings, adhesives, etc.

In addition, from the perspective of market positioning and price, there are also certain differences between polyester grade and industrial grade glycol polyester. Polyester-grade ethylene glycol polyester is often positioned at a higher end, the price is higher, and the market demand is relatively stable; while industrial-grade ethylene glycol polyester is for the mass market, the price is relatively low, but the market demand is large.

To sum up, there are obvious differences between polyester grade and industrial grade glycol polyester in terms of raw materials, production process, performance and market positioning. In practical applications, users need to choose appropriate specifications and varieties according to specific needs and requirements, so as to give full play to the excellent characteristics of ethylene glycol polyester and provide strong support for the development and application of various industries.
