用途 Usage:

1,4-环己烷二甲醇主要用于聚酯型材、聚酯纤维、不饱和聚酯树脂，如 PETG、PCT、PCTG、PCTA 等，可增强聚酯化合物的反应活性，提高聚合物的水解稳定性、可塑性、光泽度、透明度、印刷性、加工能力。CHDM 也可用于涂料(粉末涂料)，可提高涂料的耐低温性和耐侯性，提高光泽度。

CHDM is mainly used in polyester section, polyester fibers,unsaturated polyester resin, such as PETG, PCT, PCTG, PCTA, etc. which could enhance the reactivity in polyester compounds and improve the hydrolytic stability, plasticity, gloss, transparency, printability, process ability of polymer. CHDM could also be used in coating application(powder coating), which could enhance low temperature resistance & weather ability of coating, and improve the gloss.
