Aramid paper was selected as an urgently needed material for advanced rail transit
In order to accelerate the development of the new materials industry, the three ministries and commissions of the National Development and Reform Commission, the Ministry of Finance, and the Ministry of Industry and Information Technology recently jointly issued the "Implementation Plan for the Upgrading and Upgrading of Key Materials".Among them, aramid paper was selected as the “material urgently needed in the advanced rail transit industry” for its good performance and broad market space. The “Plan” clearly stated that "it supports the industrialization and demonstration application of aramid paper for honeycomb core materials. The tensile strength of aramid paper is greater than 3.2 kN/m, the temperature resistance exceeds 210 ℃, the flame retardant grade is VTM-0 or V-0, and the annual production capacity of aramid paper reaches 1,500 tons."
In recent years, with the rapid development of the high-speed rail industry, the related new material industry has ushered in a wave of rare development opportunities.As an important structural material, the honeycomb structural material made of aramid paper has the characteristics of flame retardant, corrosion resistance, high strength, lightweight, excellent sound insulation and noise reduction. Its specific strength is 9 times that of steel and higher than that of aluminum honeycomb.It is widely used in the floors, side walls, ceilings, window frames, luggage racks and various cabinet mezzanines of high-speed rail and motor vehicles, and has become an indispensable strategic new material.
As a leading enterprise in the domestic aramid paper industry, Yantai Minshida Special Paper Co., Ltd. currently has a production capacity of 500 tons of aramid paper, and the expansion project of more than a thousand tons has been put on the agenda. As early as 2011, the company's Metastar® Aramid paper products have passed the certification of UL in the United States.The company said that it will make full use of the golden opportunity for the development of the industry, accelerate the promotion of aramid paper in rail transit, aerospace and other related fields, and make due contributions to promoting the upgrading of the material field and the development of the rail transit industry.
