According to the statistics of relevant institutions, the current development of new energy vehicles, intelligent robots, home appliances and other fields is relatively fast. In order to meet the demand for plastic products in these fields, various plastic products are emerging one after another. New plastic products in the market are still coming out, and we are trying to further promote the development of these fields. The advent of new products is inseparable from the efforts of major plastic enterprises and research institutions. Here, we will take a look at the technical achievements and breakthroughs in related fields.

German Industrial Plastics Processing Institute

Recently, the research team of the German Industrial Plastics Processing Research Institute is studying the economical glass fiber reinforced plastic (FRP) based on thermosetting plastics processed by injection molding. It is understood that this newly developed FRP has the characteristics of high strength and low density, and has great prospects in the automotive manufacturing and aviation industries. This FRP process is based on thermoset plastics, rather than the usual thermoplastics-based process, which increases the economics of FRP production while simplifying the production steps of FRP and shortening the production cycle.

Solvay

Recently, Solvay Performance Technologies has launched a new product, Technyl® Red J. According to the relevant person in charge, this product is developed by Solvay in the automotive manufacturing process, the traditional high temperature resistant material is too brittle and difficult to maintain the required heat resistance, pressure resistance and chemical resistance for a long time. It is understood that this new product is based on the patented PA66 / 6T technology, can maintain 2000 hours in 220 ° C environment or 3000 ° C heat aging performance in 210 ° C environment, while its chemical resistance and pressure resistance also performance Excellent.

Exxon Mobil

As one of the world's largest chemical companies, ExxonMobil has introduced a new polymer that goes beyond XP 8784. This new product not only has excellent toughness, rigidity and sealing properties, but also improves packaging speed and reduces the use of packaging materials. It can be widely used in laminated bags, frozen films and other fields.

DSM Group

The Royal DSM Group has entered into a partnership agreement with Chromatic 3D Materials to introduce thermoset materials for 3D printing products. The DSM Group's vast global market will be combined with Chromatic 3D's technology for thermosetting materials for 3D printing, which will greatly improve the properties of thermoset materials in terms of adaptability, durability and flexibility. . This strong alliance will also bring high-performance, industrial-grade 3D printing solutions to the manufacturing industry.

Lubrizol

Lubrizol Corporation has announced that it will launch its newly developed new specialty polymer in the near future. The polymer can “improve materials and improve performance”, with strong color and visual impact, and can bring Lubrizol expertise. Perfectly integrated with the terminal application. The relevant person in charge of Lubrizol stressed that “improving materials and improving performance” is Lubrizol’s mission and enthusiasm. The newly developed new specialty polymer not only fills the gap between flexible rubber and rigid plastic, but also makes the product safer and stronger, thus achieving better end product performance while improving aesthetics and sustainability.

Zhejiang University

Professor Zhang Lin from the College of Chemical Engineering and Bioengineering, Zhejiang University combined the Turing structure with membrane research to create a nanoscale Turing structure on the membrane. After a large number of experiments, the research team found that polyvinyl alcohol is the best effect as a hydrophilic macromolecule that inhibits the diffusion of reactants. The hindrance of the polyvinyl alcohol to the reactants results in a Turing structure on the smooth and smooth surface of the film, and this Turing structure can enhance the water permeability of the film. The experimental results show that the membrane has a water permeability of 3-4 times that of the original, and the membrane will reduce the water production cost and improve the water separation efficiency.

summary

Thanks to the efforts of major plastics companies and research institutes at home and abroad, new breakthroughs have been made in new plastic products and processes. These new products and new processes will enhance the competitiveness of related companies in their respective fields and become a new driving force for corporate economic growth. The achievements of these institutions will also promote the development of the plastics industry, drive the development of related downstream industries, and inject new vitality into the economic development.

Duplex Stainless Steel

Duplex Stainless Steels Available

Haohua Industrysupplies LDX2101, 2205, Ferralium 255, Zeron 100 and LDX2507 in the form of plate, sheet, strip, bar, pipe, tubing, pipe fittings, flanges and weld wire.

Duplex Stainless Steel Overview

Duplex Stainless Steels, also referred to as austenitic-ferritic stainless steels, are a family of grades with about equal proportions of ferrite and austenite. These steels have a duplex microstructure which contributes to their high strength and high resistance to stress corrosion cracking. Due to their high content of chromium, nitrogen and molybdenum, duplex steels offer good resistance to local and uniform corrosion. Duplex stainless steels have good weldability.

Today, modern duplex stainless steels can be divided into three groups:
Lean Duplex such as LDX2101
Standard Duplex such as 2205, the work-horse grade accounting for more than 80% of duplex usage
Super Duplex such as Ferralium 255 and Zeron 100 and LDX2507

Of the duplex grades, duplex 2205 is the most widely used. However, the super duplex steels like Zeron® 100 and LDX2507 are excellent for servicing severe corrosive environments, such as offshore and marine applications. Lean duplex 2101 is available as an economic alternative to 300 series stainless steels.
