Meirui polyurethane radiates new energy

Polyurethane may be the first you've heard of it, but it's actually deeply integrated into our daily lives. From the plastic track in the stadium, to the skin of the football, to the soles of sports clothing and sports shoes, polyurethane is everywhere. In addition, in transportation, whether it is the high-end paint on the outer layer of cars and aircraft, or the internal dashboard, seats, etc., polyurethane is one of the indispensable raw materials. Its application is very wide, covering textile, construction, aerospace, shipping, transportation, medical health, electronic products and other fields, almost in all the industries that need high-performance materials, you can see its figure.

"Polyurethane is currently the largest variety of polymer materials, the most widely used, the fastest growing special organic synthetic materials, known as the 'fifth plastic'." On November 7, in the exhibition hall of Meirui Polyurethane New Material Industrial Park in Baoshan Economic and Technological Development Zone, Fu Shaohua, a project construction engineer, introduced and pointed to a variety of polyurethane products in the display area.

We will accelerate the extension and replenishment of the industrial chain

Standing at a height overlooking the Meirui Polyurethane New Material Industrial Park, what you see is a network of complex pipes, which are like a silver python, reflecting cold light under the sunlight, winding and closely connecting equipment of different scales.

At present, polyurethane, as an important part of the city's "trimerization" industry, is taking Meirui polyurethane new material Industrial Park as the carrier and Meirui technology as the lead to accelerate the extension and complement of the industrial chain. It is committed to creating an upstream and downstream integrated polyurethane industrial park from basic chemicals to high-end new materials, which provides a strong support for promoting the development and growth of the new material industry in our city.

Meirui polyurethane new material industrial park integration project

It is jointly built by Meirui New Materials Co., LTD and Hebi Coal Chemical Co., LTD of Henan Energy and Chemical Group. Meirui New Materials Co., LTD is a well-known manufacturer of thermoplastic polyurethane elastomers (TPU) in China. The project is divided into two phases, the first phase of the project will start construction in 2022, with an annual output of 120,000 tons of special isocyanate, 150,000 tons of nitroaniline, 120,000 tons of phenylenediamine and 100,000 tons of cyclohexane diamine production capacity. The project developed four first sets of technology, successfully breaking the foreign technology monopoly.

The world's largest single set of industrial plant production capacity

A few days ago, the annual output of 5,000 tons of PPDI (p-benzene diisocyanate) device, an annual output of 100,000 tons of HDI monomer (Hexamethylene diisocyanate) device has been successfully put into operation. As the key raw materials for the synthesis of special polyurethane elastomers, these products can significantly improve the resilience, wear resistance and other properties of new polyurethane materials, and are widely used in automotive, Marine, aerospace and other fields. It is worth mentioning that its PPDI device and HDI device are currently the largest single set of industrial devices in the world.

For a long time, these products have been monopolized by foreign giants such as BASF, resulting in high market prices and limited supply. After years of independent research and development, Meirui has successfully mastered the core technology and process flow with independent intellectual property rights, effectively filling the domestic technology gap.

"The successful operation of the unit marks the successful application of our most critical phosgenation technology and continuous ammoniation technology in the project, and lays a solid foundation for the continuous production of the subsequent unit." "Our technology not only performs well in terms of energy saving, environmental protection, product quality and reliability, but also greatly enhances our market competitiveness," Fu said.

Accelerate the formation of functional new material industrial clusters

At present, the product performance indicators have reached the expected goals, the company is further optimizing the process parameters, continue to improve the quality of operation, and strive to achieve production and efficiency as soon as possible. At the same time, actively promote the trial production of the remaining devices, and strive to put into full production as soon as possible.
