Superhydrophobic LLDPE/SiO2 Nanoparticles Coatings

A new study deals with the fabrication of durable porous and non-porous superhydrophobic LLDPE/SiO2 nanoparticles coatings with excellent self-cleaning property. Echemi

In a current work, SiO2 nanoparticles embedded linear low density polyethylene (LLDPE) superhydrophobic coatings on glass substrates were fabricated using dip-coating technique. Porosity of SiO2 nanoparticles coupled LLDPE superhydrophobic coatings was also varied using non-solvent (ethanol) by employing phase separation method. Surface morphology, water contact angle, self-cleaning and water-repellency of coatings were characterized. Furthermore, the stability of these coatings was also evaluated by conducting thermal, chemical and mechanical stability tests at perturbation conditions.

Porous coatings more durable

Along with, comparative studies of porous and non-porous LLDPE/SiO2 coatings on their performances were presented in the current work. By creating porosity and/or embedding SiO2 nanoparticles in to LLDPE matrix, superhydrophobicity is achieved with water contact angle of 170° and sliding angle of 3.8°. Coatings exhibit the excellent self-cleaning property. Their superhydrophobic property is also maintained after annealing in temperature range from 40 to 120 °C. Water jet impact test reveals the excellent water repellent nature of coatings. Non-porous coatings exhibit more stability in pH range from 2 to 9 than porous coatings. By abrasion test with micro-fiber cloth and tape peeling tests, it is observed that porous coatings are more durable than non-porous coatings. The aforesaid coatings have great industrial applications.

Polymeric MDI Market Forecast in 2018

Introduction: In the first three quarters in 2017, the Chinese MDI market performed actively. However, the polymeric MDI prices slumped in Q4, 2018. In 2018, though the supply will see some changes, the oligopoly will still exist in the market. It is hard for polymeric MDI market prices to move high and the prices won’t be too low.      

In the first three quarters in 2017, the Chinese polymeric MDI market performed actively. However, the polymeric MDI prices slumped in Q4, 2018. With the coming Spring Festival, most players had retreated from the market. Today, Echemi will forecast the overall polymeric MDI market trend in 2018.  Isocyanates  category

First, the supply of MDI in 2018 will increase slightly from 2017.

In 2018, the 240kt/a unit at Shanghai Lianheng Isocyanate (144kt/a capacity of polymeric MDI) is expected to be put into operation in March. Moreover, the 400kt/a unit at Sadara runs normally, and around 40%-50% goods will flow into China. The overall supply structure of polymeric MDI will change in 2018. In 2018, major suppliers are: Wanhua Chemical, BASF, Covestro, Huntsman and Sadara. The competition will be fierce.          

Second, the downstream demand will remain modest.

In 2018, the downstream industries will remain weak. The refrigerator industry saw high prices of raw materials in 2017. The overall operating rate in 2018 will be fine and increase according to the expected. Supported by related policies, the external wall insulation industry will increase stably.   

Third, production cost has limited influence on the MDI market.

According to Echemi’s Regression Analysis Model, the R value of polymeric MDI and benzene, polymeric MDI and aniline is 0.03 and 0.13 respectively. The P value is less than 0.05. Benzene and aniline prices have limited influence on the polymeric MDI market.     

Finally, off-season and peak seasons influence the market.

Q1 is the traditional off-season and market prices will decline. In Q2, influenced by the busy farm season, it is difficult for the polymeric MDI market to move up. Q3 is the traditional peak season. Refrigerator, heat preservation industries will be good, which will promote the polymeric MDI market. In Q4, the market will enter the downtrend again.    

According to Echemi, the polymeric MDI market in 2018 cannot copy the high levels in 2017 and the overall prices won’t be too low. The market prices will be in the range of RMB 20,0000-28,500/mt in cash. Lowest prices may appear in May and the highest price may appear in September. 

Echemi - Chinese Pentaerythritol Market Inched Down in Feb 2018

Echemi Market review: In February, the dealing prices for 95% pentaerythritol were quiet. Raw materials prices moved marginally, and the support to pentaerythritol was weak. Influenced by the traditional Spring Festival, upstream and downstream users retreated from the market. Up to February 28, delivered prices for 95% pentaerythritol in East China were in the range of RMB 11,600-12,300/mt. Mainstream prices for 98% pentaerythritol were in the range of RMB 12,500-13,500/mt. Prices for 99% pentaerythritol were in the range of RMB 13,500-14,000/mt.   

Forecast: Prices of raw materials decline recently and the effect on the pentaerythritol market is not obvious. In March, the raw materials won’t support the pentaerythritol market. Downstream users come back the market gradually, and they will mainly consume inventories stocked before. The demand for pentaerythritol will be weak. On the whole, the Chinese pentaerythritol market will continue to inch down.

2015-2017 China Butyl Acrylate Export Analysis

Introduction:

From 2015-2017, the total export volume of butyl acrylate increased obviously. According to the figure below, in 2017, the butyl acrylate export volume was 135,754mt, which was up 110% from 64,071mt in 2016. The average export price of butyl acrylate increased 30.6% Y-O-Y. Compared with butyl acrylate export in 2015, the average price changed a little, while the export volume of butyl acrylate doubled in 2017. 

According to customs data in figure below, the export volume of butyl acrylate increased obviously in most of customs. The export volume in Nanjing Custom increased the most. According to the data, the export volume in Nanjing Custom was 53kt, and the volume was only 23kt in 2016, which was up 130% Y-O-Y. Furthermore, the export volumes of butyl acrylate in Guangzhou and Qingdao Customs increased significantly as well.

According to the form below, in 2015 and 2016, only the export volumes of butyl acrylate in Nanjing, Hangzhou and Shanghai were over 10kt. Furthermore, in 2017, the export volumes in Guangzhou and Qingdao increased over 10kt as well.

According to the figure below, the export volume in mainstream factories increased significantly. The export volume in Satlpec was the most (48kt), which accounted for 35% of total export volume in 2017. The next ranking was Shengke Chemical. The export volume increased from 8,819mt in 2016 to 25,824mt in 2017, which was up 193% Y-O-Y. Furthermore, the export volumes of BASF-YPC Company and Wanhua Group increased dramatically. In butyl acrylate export market, there are three mainstream export companies in East China, which are Satlpec, Shengke Chemical and BASF-YPC. Wanhua is the major company in North China, and Jiangmen Qianxin is the major company in South China.

In general, as the export volume in mainstream companies increased significantly in 2017, the total export volume of butyl acrylate followed in 2017. The units were shut unexpectedly or became deteriorated in foreign companies, which provided more opportunities for Chinese butyl acrylate companies. It is predicted that the Chinese butyl acrylate price and output will become more and more important in international market.

Chinese DMC Market Ran Upwards Continually (Dec 8-14, 2017)

During December 8-14, the Chinese dimethyl carbonate (DMC) market was stirred up. The downstream market was thin, which did not support the demand for DMC. Furthermore, the DMC units in East China restarted gradually. However, as the inventory was low and factories operated for previous contracts, the supply was flat. Moreover, influenced by the air pollution control, the supply of DMC was unclear. With the propylene oxide (PO) price increasing continually, the DMC producers felt hard to purchase raw materials, which supported players’ sentiment. As a result, the DMC offers went upwards. The downstream users showed poor interest in purchasing, because they stocked goods before. The trades were flat in the DMC market. The negotiation price of Chinese DMC was in the range of RMB 6,400-6,700/mt by acceptance.

Demand for Propylene Glycol Was Limited and the Market Decreased

Demand for Propylene Glycol Was Limited and the Market Decreased (Aug 25-31)

The propylene glycol market continued decreasing this week. As the supply in North China declined, the propylene oxide (PO) market stopped decreasing and the PO price was RMB 12,000/mt. The units in Yankuang Group, Shandong Depu Chemical, Shandong Wells Chemicals and Linggu Chemical underwent maintenance, and did not restart yet.The operating rates in Shandong Shida and Haike Group were in a low level. The propylene glycol factories had less sale pressure. The prices showed a downtrend. The holders were willling to sell their goods in a high price. The negotiation was quite low.

The operating rate in downstream was in a low level, influenced by the environment protection supervision. The demand for propylene glycol was limited, the inventory in part of factories was still sufficient and users had weak interest in stocking goods.

In mid-week, the few low-priced prders were on a need-to basis. Up to August 31, the mainstream quotation of propylene glycol was in the range of RMB 9,100-9,600/mt by acceptance. The dealing prices were flexible.
