The industrialization process of plastic nanocompo

The industrialization process of plastic nanocomposites in the world has been delayed.

at the third European additives and colorants conference held in Antwerp, Belgium recently, Robert Schall of SUD Chemie, a German nano clay manufacturer, believed that it would take longer than originally expected to use nanocomposites to reach a certain market size. The problems encountered in accelerating its industrialization process show that the previous prediction is too optimistic. A series of thin-film materials with chiral separation function and catalytic work that can further improve the utilization of waste packaging have been developed (chem. commun., 2017, 53, 1470; ACS appl. mater. interfaces, 2017, 9, 7259 for the second error; inorg. chem., 2017, 56, 3526; nanoscale 2017, doi:10.1039/c7nr02284k)

albert Schall pointed out, In 1999, the research report proposed by the analysts of Principia partner consulting company estimated that the world's use of nano fillers for barrier packaging would reach 48kt by 2004, and further increased to 166.7kt in 2009. It is expected that the demand for automotive applications will be 23KT within two years, and will soar to 156.8kt in 2009. These goals now seem to be unattainable, because the time for the industry to promote new applications is much longer than originally expected, At present, the fastest practical application of plastic nanocomposites is the wire and cable industry, which uses nanoparticles to improve the flame retardancy of materials, followed by the packaging industry, and then the automotive industry

now many nano particle filled polymers are starting the application market. TPO (thermoplastic polyolefin) nanocomposites developed by polyolefin manufacturer Basell are used in some models of General Motors (GM) to improve the strength of materials. Bayer of Germany, UBE of Japan and Honeywell of the United States are promoting the market of nylon 6 nanocomposites for food packaging. Nanoparticles can reduce the gas transmission rate and improve the transparency of the materials. RTP in the United States, Yukio in Japan and unitika in Japan are producing materials similar to nylon 6/nylon 66 blends. Eastman Chemical Company of the United States has pet/Nylon Nanocomposites for the production of fruit juice bottles and beer bottles. It uses the characteristics of nylon/nanocomposites to reduce the permeability of oxygen and carbon dioxide, but it can still master public opinion. Germany SUD Chemie and kabelwerk Eupen are carrying out market development of ldpe/eva cable insulation filled with flame-retardant nanoparticles

Samuel Konig, the head of the Israeli plastics and rubber center, also believes that the pretreated and optimally oriented nanoparticles have great potential in the development of flame retardant polymers. The nanoparticles are coked during combustion to prevent polymer dripping. The surface treatment process of highly stripped and polymer compatible nanoparticles is complex, and the price is still not low. Although its addition is the smallest, generally only 4% - 5% (weight fraction), the processing plant expects a cheaper price. It seems that it is not feasible at present, and the process of massive promotion has to be postponed
