As a widely used material, plastic plays an important role in our life. The plastic PE and PT are two common plastic materials, they have their own unique characteristics. Next, we will reveal the difference between plastic PE and PT and see their respective characteristics.

let us know about plastic PE. PE is short for polyethylene. It is a thermoplastic with good heat resistance and cold resistance. Because of its good flexibility and toughness, it has been widely used in packaging, bottles and other fields. In addition, plastic PE also has good chemical stability, and has good resistance to chemical corrosion such as acid and alkali. Therefore, plastic PE also has important uses in chemical, food and other industries. In addition, plastic PE also has good electrical insulation properties, so it is also widely used in the power industry.

Next, let's take a look at plastic PT. PT is the abbreviation of polyethylene terephthalate, which is a special engineering plastic with good mechanical properties and heat resistance. The thermal deformation temperature of plastic PT is higher, and it can be used for a long time at a higher temperature without deformation. In addition, the corrosion resistance of plastic PT is also very good, and it has good corrosion resistance for some chemicals. Due to its excellent heat resistance and corrosion resistance, plastic PT has been widely used in automotive, electronics and other industries. In addition, plastic PT also has good processing performance, can be injection molding, extrusion, blow molding and other processing methods, so in the production of plastic products has an important position.

in the use of the environment, plastic PE and PT also have some differences. Plastic PE is mainly used in low temperature environment, and its low temperature resistance is good, so it has been widely used in cold areas. The plastic PT is mainly used in high temperature environment, so it has an important position in some high temperature environment engineering.

In general, plastic PE and PT each have unique characteristics and application areas. When choosing to use, you need to choose according to the specific usage scenarios and requirements. I hope that through this article, everyone can better understand the difference between plastic PE and PT, and choose more suitable plastic materials for their lives and work.
