Aramid paper is a special paper made of pure aramid fiber. It has the characteristics of high strength, low deformation, high temperature resistance, chemical corrosion resistance, radiation resistance, flame retardancy and excellent electrical insulation. It is widely used in aerospace, national defense industry, transportation, energy and power fields.
SDMS Aramid Paper Technology Corporation is committed to R&D and manufacturing of high-performance Aramid paper and aramid paper honeycomb core material.
In 2010, the high-performance aramid paper developed by the company successfully entered the ABB global supply chain. Since then, SDMS has opened the door to the international high-end aramid paper market.
In 2013, the second aramid paper production line of SDMS was successfully rolled off the production line, and the aramid paper produced by SDMS surpassed similar products in the world in "breadth"
The R&D team of the company has broken through the key technical problems of the industry one by one, successively developed a series of products such as meta aramid paper and para aramid paper, and realized the industrial production of kiloton aramid paper.
The successful launch of the company's high-performance aramid paper has broken the exclusive monopoly of foreign enterprises at one stroke, making China the second country in the world to be able to produce high-performance aramid paper. At the same time, it has also laid the foundation for SDMS in China's aramid paper industry, and created a new era of aramid paper national production.
The company was rated as the invisible champion in the field of high-performance aramid paper by the Ministry of Industry and Information Technology of China.
The aramid paper developed by the company can be divided into two categories: aramid paper for electrical insulation and aramid paper for honeycomb core material according to its good mechanical properties and high temperature insulation resistance
The temperature resistance grade of aramid paper for electrical insulation, which is UL certified, is 210 ℃. The mechanical and electrical products made of aramid paper can reach the temperature resistance insulation grade above Class H (180 ℃).
As aramid paper does not deform and melt under high temperature, the ability of mechanical and electrical products to temporarily withstand overheating and overload is improved. Moreover, using aramid paper as insulation material can make mechanical and electrical products compact and durable, and its size and weight are greatly reduced.
Aramid insulating paper is mainly used for:
Insulating materials for coils and windings in transformers, insulating materials for insulating sleeves, parts, wires and joints;
Coil winding, slot to slot, phase to phase, turn to turn, line terminal insulation materials in motor and generator; Cable and conductor insulation, nuclear power equipment insulation materials, etc., representative products include dry-type transformers, locomotive traction motors, mine underground motors, microwave oven transformers, etc.
Aramid paper honeycomb core material is mainly made of aramid paper honeycomb core material structure, which has the characteristics of light weight, impact resistance, high strength, aging resistance, etc.
It is mainly used for aircraft, missiles, satellite broadband wave transmitting materials, and highly rigid sub stressed structural components (wings, fairing, cabin liner, aircraft doors, floors, cargo compartments, and partitions).
Aerospace
The aramid paper developed by SDMS has been successfully applied in China's aviation industry since 2009. Later, it has been applied in batches in many other aviation models and has become its exclusive supplier.
SDMS invested more than 20 million yuan to upgrade key production equipment and build aramid honeycomb paper laboratory in order to produce high standard aviation honeycomb base material aramid paper that meets the requirements of C919 large passenger aircraft.
After more than two years of technological innovation and accumulation, more than 200 experiments and nearly 10000 product tests, the company finally successfully passed the test of COMAC, and the company's technical team finally mastered this cutting-edge technology at the international forefront.
After being successfully applied to C919 large passenger aircraft, the aramid paper, an aviation honeycomb substrate developed by the company, has successfully passed the inspection of test vehicles of five airlines around the world, and has been applied to aircraft of many international mainstream airlines.
In 2016, SDMS created the only high-performance wet manufacturing equipment of multi stack mesh in China, innovatively proposed low-temperature plasticizing and hot pressing technology, and obtained international invention patent authorization, realizing the improvement of project quality and efficiency, energy conservation and consumption reduction, while making the overall performance index of products comparable to international products.
In order to comply with the arrival of the industrial Internet era, SDMS directly applies the unique physical and chemical properties and ultra-high strength of aramid paper to the optical cable structure, improves and improves the application performance of optical cables, and helps the installation and deployment of 5G base stations in the future.
In recent years, SDMS has continuously developed new products;
High flame retardant aramid paper;
High modulus para aramid paper;
Aramid paper with high thermal conductivity and high corona resistance;
High heat resistance and insulation aramid paper;
High strength, light weight, corrosion-resistant aramid paper and other customized products.
The chlorine content of the low chlorine products developed by the company is more than 70% lower than that of similar products abroad.
So far, SDMS has developed more than 3 aramid paper series products with more than 100 specifications, which are widely used in electrical and electronic, rail transit, new energy vehicles, aerospace and other fields.
