DuPont owns and operates world-scale continuous polymer materials plants worldwide, and sets up polymer modification plants in 13 countries to ensure that local customers are delivered locally.
Nylon 612 was first developed by DuPont. At present, the product has been sold in various brands and is widely sold in the market.
Nylon 1010 stands for Enterprise: Arkema
In 1958, Shanghai Saifu Company used castor oil as raw material to synthesize China's only original nylon product PA1010, which has so far been produced exclusively by China. The main production enterprise is Suzhou Hanpu Polymer Materials Co., Ltd., and France Arkema 2011. Acquired this Chinese company.
In 2013, Arkema announced that the company's production facility in France used castor oil as raw material to produce new nylon 1010 products. The product is 100% renewable raw materials, has good rigidity, thermal stability, and gasoline and gas The permeability and processability are expected to replace high-performance polyamides.
In addition to Suzhou Hanp, Arkema previously acquired castor oil derivatives sebacic acid producer Casta (Hengshui) Co., Ltd., and an Indian company engaged in castor oil production. This series of comprehensive raw materials to polymers The integration will help Arkema's R&D and production of bio-based nylon 1010.
Nylon 46 stands for Enterprise: DSM
In 2014, DSM introduced an innovative solution for automotive rail tensioner rail panels - Stanyl polyamide 46 (PA46). PA46 is compared to the widely used Stanyl polyamide 66 (PA66). The rail panel manufactured with this product has a 25% lower coefficient of friction, 4 to 7 times higher wear resistance than PA66, and a 1% reduction in fuel consumption.
Stanyl polyamide 46 surpasses most competitors, such as PA6 and PA66, polyphthalamide (PPA), acetal and PPS, and its wear resistance is even up to 7 times that of PA66. It has its own limitations, such as brittleness (PPS and PPA materials), decreased rigidity at high temperatures (POM, PPS, PA6, PPA materials) or high wear (PPS).
Stanyl TW341 is the industry standard material for engine parts at this stage. DSM has also developed a new type of Stanyl TW371 material with better friction resistance for the new generation of engines. This material has advantages in reducing CO2 emissions and improving fuel efficiency. More significant.
Nylon 4T stands for Enterprise: DSM
As the world's leading producer of high-temperature nylon (PA46), DSM has the world's only industrialized dibutylene diamine solution. Butylenediamine is a key raw material for the synthesis of PA46. This technical advantage also enables DSM to take the lead in developing this raw material. PA4T products.
This first new polymer of the 21st century has excellent space stability, lead-free soldering compatibility, high melting point, high hardness and mechanical strength in case of temperature rise, and is in contrast to the original DSM company. PA46 product, even PA9T, it shows ultra-low water absorption.
The comprehensive and outstanding performance of PA4T will make it occupy an important share in high temperature applications such as electronics, electronics, and automobiles. The invention of PA4T is also a reflection of the market's miniaturization and higher concentration of electronic products for performance materials.
Nylon 6T stands for: Mitsui Chemicals
ARLENTM is a high temperature resistant nylon developed by Mitsui Chemicals, Japan. It is a modified nylon 6T based on terephthalic acid, adipic acid and hexamethylenediamine. Its melting point is as high as 310°C.
ARLEN's main features are excellent high temperature rigidity, dimensional stability and chemical resistance. The excellent characteristics make ARLEN have a wide range of applications in many areas including automotive parts, mechanical parts and electrical/electronic parts.

Nylon 9T stands for Enterprise: Kuraray
PA9T was first developed by KURARAY (Kuraray Co., Ltd.) and realized industrialization. The product name Genestar is derived from the polymerization of terephthalic acid with a carbon number of 9 linear aliphatic diamides.
Genestar's water absorption rate is 1/10 of that of PA46 and 1/3 of that of PA6T, making it impossible to cause dimensional changes due to water absorption, physical properties, or blister and other abnormalities in the practical appraisal of various applications. And in a high temperature environment has a more secure stability.
Therefore, as a rising star, the PA9T shows a strong market potential. The initial consumption is on the scale of thousands of tons. With the development of other markets, the consumption will increase and the cost will drop. The automobile industry will become another major market.
Nylon 10T stands for Enterprise: Blonde Technology
As a new type of semi-aromatic nylon, PA10T has good rigidity, heat resistance, dimensional stability, processability, and low water absorption. At the same time, its raw material quinone diamine is derived from castor oil, which is more environmentally friendly and sustainable. Development requirements. One of its monomers, KD, accounts for about 50 WT% of the total monomer, which is derived from the renewable resource - Ricinus communis. The bio-carbon content of the PA10T material is between 40 WT% and 60 WT%, while the water absorption rate very low.
The commercialization of PA10T products fills the blank of independent research and development of high-temperature nylon new materials in China. The company also became the second company in China to have high-temperature nylon industrialization technology after Shanghai Jieshijie Company.
