HELF PETG/PCTG Resin: Leading Copolyester to the Next Level
What is Copolyster?
A copolyester is a copolymer synthesized by modification of polyesters, which are combinations of diacids and diols. Copolyester resins have proved to be effective in packaging applications, due to their toughness, versatility and chemical resistance. They are also frequently used in the manufacture and packaging of consumer goods and materials. Click here to learn more about copolyester.
Common Copolyester: PETG PCTG
What is Copolyster PETG?
PETG is a thermoplastic polyester that delivers significant chemical resistance, durability, and moldability for manufacturing. PETG is an adaptation of PET where the ‘G’ stands for glycol such as CHDM or NPG, which is added at a molecular level to offer different chemical and optical properties.
What is Copolyster PCTG?
Adding more CHDM into the molecular chain, typically more than 40%, we can get PCTG, which has much higher impact performance, better chemical properties and higher heat deformation temperature (HDT) compare to PETG.
