2016年中国碳纤维市场需求量为1.63万吨，市场规模为41.1亿元，同比增长24.4%。市场规模的不断提升，一方面来源于传统汽车的轻量化需求，另一方面来源于国产大飞机、商用飞机的大力发展对碳纤维的大量使用，以及机器人、民用无人机等领域对碳纤维需求的增长。

A membrane acts as a selective barrier that separates and concentrates the feed stream, allowing the constituents to pass while impurities are retained on the membrane. The constituents that pass through the membrane are termed as permeates, and those that are retained are known as concentrates or retentates. The selection of membranes for specified applications depends on the pore size of the membrane. Ultrafiltration, microfiltration, reverse osmosis, and nanofiltration are some of the membrane filtration technologies. Other membrane technologies such as membrane contractors, electrodialysis, and pervaporation are also used; however, their market share is low.

Fillers are particles that are added to materials such as plastics, concrete, and composites. These materials reduce the consumption of the binder material and improve some properties of the polymer. They are mainly used to lower the cost of material, increase density, improve thermal conductivity, and enhance other properties.

涤纶产业链可以简化为炼化-芳烃-PTA-聚酯涤纶，下游主要用于纺织行业。我国 PX 产能增长缓慢，对外依存度高，国内供应商以中石油、中石化为主，国外主要从韩国、日本等亚洲国家进口，长期以来供应商享有很强的定价权，占据产业链利润大头。我国 PTA 产能在 09-12 年大扩张，带来了严重的产能过剩，15年以来行业自发去产能，不少 PTA 装臵停车停产，市场竞争格局明显改善。下游聚酯涤纶也经过了较长的调整周期，12-15 年间江浙地区部分成本较高的中小企业停产破产、退出市场，行业逐渐走出低迷期，近两年产能利用率维持较高水平。

Flat glass commonly comes in a sheet form and is produced in a flat state. These glass components are mainly used in the construction, automotive, solar glass, and other end-use industries. Flat glass components are used in windows, doors, facades, decorations, windshields, partitions, electronic equipment, interior fittings, and furniture. It is manufactured by the float glass process.

The global nitric acid market is expected to be primarily driven by increasing use of fertilizers. The maximum amount of nitric acid is consumed in producing ammonium nitrate and calcium ammonium nitrate (CAN). However, use of ammonium nitrate is declining in Europe as well as other parts of the world because of concerns relating to nitrate groundwater contamination and changes in agricultural subsidy policies. Urea is emerging as one of the main nitrogen fertilizers, which is less costly, contains more nitrogen, and does not have many safety issues.

涤纶长丝产量占化纤总产量 60%以上，品种主要有 POY、DTY、FDY 等，产业链条为“原油-石脑油-PX-PTA-聚酯-涤纶长丝-纺织”，上游涉及石化产品 PX、 PTA 等，下游应用主要为服装、产业用纺织品和装饰领域纺织品等。 

PTFE is a polymer composed of carbon and fluorine. PTFE has a straight, long carbon backbone to which the fluorine atoms are bonded. The carbon backbone is protected by the electron cloud of fluorine atoms that form a uniform helical sheath. Therefore, it forms strong bonds, and the non-polarity of PTFE makes it extremely inert and thermally stable.
