Film-grade PET chip indicators
The successful production of film-grade PET chips depends on several key factors. We will show you the difference in the manufacturing process, viscosity, melting point, DEG content, COOH content, and agglomerate particle size. Each indicator impacts the production of BOPET films. Production Process It adopts an external additive process. The additive content between batches should […]

We have established a traceability system.
Water resistance of PET chips
So, how can we enhance the water resistance of PET chips? Research has shown that a. appropriately increasing the viscosity of PET chips and increasing the polymerization of PET macromolecules help enhance the mechanical performance of the final PET film in humid and hot environments. b. reducing the COOH content of PET chips and maintaining the mass fraction of DEG at a stable level of (1.0 ± 0.2) %, along with adding an anti-hydrolysis agent such as carbon diimide or polydicyclopentadiene at a mass fraction of 0.1% to 1.5%, contributes to improving the water resistance of PET films.
Top 10 Questions About the Transportation of Polyester Chips
Polyester chips, often called PET chips, are specialty chemicals used in textile and film industries and some other filed. When it comes to shipping PET chips, you need to know a few important things to make sure everything goes smoothly. PET chips are packed in bags made of polypropylene with polyethylene liners. They are non-toxic, […]
