With the continuous improvement of people's pursuit of quality of life, the requirements for product quality are getting higher and higher. Among all kinds of materials, plastic materials are widely used in all walks of life because of their excellent cost performance, easy processing and easy shaping. As a new type of plastic material, PCTG has gradually attracted people's attention.

So, what is the material of PCTG? Simply put, the full name of PCTG is polypropylene oxide triol ester, which is a polyester material composed of propylene oxide, glycerin and other structural monomers. Because its structure contains two active functional groups, epoxy group and alcohol group, its physical properties can be adjusted by crosslinking reaction in the manufacturing process, so as to meet the needs of different fields.

PCTG, as an excellent plastic material, has many advantages that other plastic materials do not have, mainly reflected in the following aspects:

1. good high temperature resistance

PCTG high temperature resistance is very good, its melting point is usually above 200 degrees, can operate for a long time in high temperature environment, not easy to deform or melt. This makes the PCTG material can be widely used in areas that need to withstand high temperature conditions, such as hot water cups, baking molds, etc.

2. strong corrosion resistance

compared with other plastic materials, PCTG corrosion resistance is also very good. It can withstand the corrosion of various chemicals, and can be in contact with strong acids and alkalis for a long time without change, which makes it widely used in chemical product containers, medical devices and other fields.

3. good wear resistance

PCTG has higher hardness than general plastic materials, has better wear resistance, and is not easy to scratch or wear, which makes it widely used in household appliances, toys and other fields.

, PCTG, as a new type of plastic material, has many advantages that other plastic materials do not have. At present, PCTG has been widely used in food packaging, medical equipment, household appliances and other fields, and soon there will be more areas to use it. In the future development, PCTG is expected to become a new generation of excellent plastic materials.
