Flocculation is a process that assists in particle cluster formation, thus effectually separating harmful particles from waste water. It is an essential phenomenon in industrial wastewater treatment as water usually contains organic matter such as bacteria, particles of decayed plants, and plankton, which makes it contaminated.In this report, Technavio has considered segmentation based on products, application, and geography. This report covers the present scenario and the growth prospects of the global flocculants market for the period 2017-2021.

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.

Cement additives are used to improve various properties of cement such as chemical resistance, strength, color, water reduction, waterproofing, and others.These additives are used in both residential and non-residential building andconstruction applications The global cement additives market is segmented based on end-user segment(residential and non-residential), product type (chemicals, minerals, and fibers), and geography (Asia-Pacific — APAC), North America, Europe, and rest of the world —ROW).The global cement additives market, while constituting a small portion of global industry output, has been growing at a promising rate.Sustainability has become an important consideration in urban areas. With the increase in the disposable income of individuals in developing countries such as India,China, and others we expect the increase in the demand for affordable, energyefficient housing, and effective transport systems, thereby fostering the market growth.Developing economies tend to have more subdued residential and infrastructure sectors. Therefore, the world’s largest cement producers such as CEMEX,LafargeHolcim, and others are confronting declining growth rates in their home markets and are forced to seek opportunities in emerging countries such as India,Malaysia, Brazil, Russia, South Africa, and others.

Caustic soda, also called sodium hydroxide or Iye, is a highly corrosive and reactive strong metallic base. The compound is industrially produced by membrane cell,diaphragm cell, and mercury cell processes.Caustic soda is a base chemical in many organic and inorganic chemical industries. It is also used in pulp and paper industries, textiles, alumina production, oil and gas,and water treatment industries.The global caustic soda market is likely to grow at a moderate pace during the forecast period. The market growth can be attributed to the growth in many end-user industries,such as pulp and paper, organic chemicals, and inorganic chemicals.

7 月以来，无论是乙烯还是丙烯价格均大幅上扬，累计涨幅都在 2000 元/吨，按照 2.6 的甲醇吨耗，相当于拉高了甲醇价格空间在800 元/吨左右，这也基本就是本轮甲醇的价格涨幅。展望未来几个月，由于北美飓风影响，无论是乙烯还是丙烯产能的停产比例都在 50%以上，更为关键的是，在飓风影响之前，烯烃的全球供给就已经趋于紧张，美国装置因飓风而停产无疑使本已紧张的供需更加雪上加霜，因此我们判断未来烯烃价格大概率还将维持强势，这也就保证了 MTO 装置对甲醇需求的稳定。

草甘膦装置的退出及行业开工率的变化正在复刻。草甘膦行业洗牌进展顺利，供求关系正在 发生逆转，价格反弹时产能不会大规模释放，开工率提升将是主要的供给增量。而小厂出货 量及开工率的波动性，是草甘膦价格周期波动的主要驱动力。当小厂 TTM 开工率见顶时，也 就预示着产品价格见顶。在此之前，草甘膦价格可能会因为淡季因素或者事件性影响（比如 甘氨酸环保放松）而回落，但不改上行趋势，坚定看好 2017。未来我们将重点跟踪行业 TTM 开工率的变化以及大厂小厂 TTM 开工率的变化。

行业景气度持续，企业盈利水平不断改善。受益于供给侧改革的持 续深化以及环保监管升级提升化工行业的市场集中度，化工企业盈 利水平在上半年显著改善。2017 年上半年基础化工行业上市公司共 实现营业收入 19245.36 亿元，同比增长 33.53%；实现营业利润 1024.37 亿元，同比增长 50.52%，实现净利润 848.29 亿元，同比增 长 52.58%。行业整体营业利润率 5.32%，较去年同期增加 0.91%， 整体销售净利率 4.41%，同比增加 0.86%。 二季度行业去库存顺利结束，三季度周期品轻装上阵进入“金九银 十” 。二季度行业整体延续同比大幅增长势头，炭黑、钛白粉、聚氨 酯等子行业净利润同比增长靠前。受行业去库存等因素影响，二季 度化工品价格环比有所回落，但下游需求稳中向好，随着去库存的 顺利完成，行业目前进入需求的旺季，来自环保等对供给收缩的压 力不断增强，周期涨价行情有望在三、四季度阶段上演。

由于市场担心朝鲜核问题引发的地缘政治冲突威胁国际原油贸易运输，油价反弹。至 9 月 8 日收盘，Brent 原油期货收于 53.78 美金/桶，较上周末上涨 1.95%；NYMEX 期货价格收于 47.48 美金/桶，较上周末上涨 0.40%；周均价分别为 53.61 和 48.35 美金/桶，涨跌幅分别为+3.15%和+3.54%。美元指数收于 91.33， 较上周末下降 1.64%。2017 年 9 月 1 日美国原油商业库存 4.624 亿桶，较之前一周上涨 460 万桶；汽油库 存 2.267 亿桶，较之前一周减少 320 万桶；馏分油库存 1.478 亿桶，周环比减少 140 万桶；丙烷库存 7990 万桶，周增加 635 万桶。9月 8 日美国钻机数 944 台，与上周增加 1 台，年增加 436 台；加拿大钻机数 202 台，周数量增加 1 台，年增加 68 台。其中美国采油钻机 756 台，周数量减少 3台
