摘要
指出PET树脂的市场价格低于PE和PP是一种价格扭曲现象,分析了出现这种现象的原因在于PET的生产成本高,PET树脂的熔点高,易吸水,塑料加工难于PE和PP。论述了使用混合二甲苯氧化制混合苯二甲酸,再用它制造塑料级低熔点聚酯树脂专用料(PEM)在技术上是可行的,经济上是合理的。
It is pointed out that the market price of PET resin is lower than PE and PP. It is a price twisted phennomena. The causes of this phenomena is that the production cost of PET is high. The PET resin is easy to obsorb water, the melt point of it is high, its plastics processing is more difficult than PE and PP. It is feasible in technique and reasonable in economy that using the mixed xylene oxidation to manufacture mixed phthalic acid, than using phthalie acid to produce plastic grade low melt point PET resin special material.
