Yisheng PET resin is a polyester material produced by Yisheng Petrochemical Co., Ltd., with an annual production capacity of 3.8 million tons. The main models are YS-W01, YS-Y01, YS-H01,YS-C01, YS-C02. The resin has the characteristics of good color value, low acetaldehyde content, stable viscosity, low processing temperature, wide processing range, high product transparency, high yield rate, and can effectively ensure the unique taste of the packaging.
This resin is widely used in beverage bottles, cooking oil barrels, lotion bottles and other transparent bottle products as well as PET sheets. Among them, PET sheets are commonly used in electronic trays, fruit and vegetable trays, takeaway packaging boxes, toy boxes and other products. Yisheng PET chips are not only sold all over the country, but also exported to Southeast Asia, South America, Africa, Europe and other regions, and have a high reputation and market share in domestic and foreign markets.

Main Performance of Yisheng PET Resin
The glass transition temperature of Yisheng PET resin is about 80℃, it has good toughness at low temperature, the melting point is about 255℃, and it has excellent processing fluidity in the molten state. It has good corrosion resistance to many chemicals, can resist a variety of organic solvents and inorganic acids, and has good impact resistance, and can resist external impact to a certain extent.
