今年以来，PTA成本端原油和PX价格不断上涨，辅料醋酸的价格明显抬升，大幅挤压了PTA工厂的利润。低利润下装置检修增加，部分装置开启长停，而需求端聚酯开工率持续维持高位，供需错配情况下，3月起PTA进入去库存通道。近期，受台风“烟花”的影响，长江封航，主港区主流货源紧缺，PTA基差持续走强，价格重心不断抬升，PTA产业链利润整体回升。

The Hydrogen Free Diamond Like Carbon Coatings DLC market is expected to grow strongly with the growth in the automotive industry, also increasing demand for high temperature coatings is providing huge opportunities for the DLC manufactures. The demand for hydrogen-free DLC is largely used by number of end-use industries due to its rigidity and wear resistance when compared to DLC that is combined with hydrogen. In the automotive sector hydrogen-free, DLC coating combines appropriately with the engine oil, which results in forming strong ultra-thin film when special oil additives are applied. Low friction factor and advanced abrasion resistance are increasing the demand for the DLC market. Manufactures in biomedical and automotive industry are aiming to use hydrogen-free DLC for effective working. Additionally, innovative technologies such as pulsed laser deposition and plasma enhanced CVD are expected to trigger the market for DLC
