PETG is diverse types of polyester, two common types of alcohol for EG / CHDM. By the PTA, EG / CHDM a total of condensation and the formation of polyester for PETG. In response, CHDM the cis-isomer of constant change. Such as molecular chain of condensation of the regular destruction of the crystallization of greatly reduced, in a certain ratio, can be completely amorphous of the total polyester.
PETG manufactures high degree of transparency, luster, and excellent impact strength, chemical resistance performance, good resistance patience, good mobility, good health, are widely used in sheet, plate, film, bottle blow molding category, food and pharmaceutical packaging, Cosmetics, and other fields. |
