Nylon yarn

The most comprehensive nylon representative enterprises in the history

The representative enterprise of Nylon 46 : DSM

In 2014, DSM launched stanyl polyamide 46 (PA46), an innovative solution applied to the guide plate of automobile chain tensioner. It is reported that compared with stanyl polyamide 66 (PA66), PA46 can reduce friction coefficient by 25%, wear resistance by 4-7 times higher than PA66, and fuel consumption by 1% at the same time. Ford Motor Company test shows that at 90 ℃ oil temperature and engine speed, the loss torque of PA46 is 0.45n · m lower than that of PA66, which is equivalent to 2 grams of carbon dioxide emissions per kilometer. The performance of stanyl polyamide 46 is better than that of most competitors, such as PA6 and PA66, PPA, acetal and PPS, and its wear resistance is even 7 times of PA66. And the above materials have their own limitations, such as brittleness (PPS and PPA materials), rigidity drop at high temperature (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 started to develop new stanyl tw371 materials with better friction resistance for the new generation of engines. The material has more advantages in reducing carbon dioxide emissions and improving fuel utilization.

Nylon 4T representative enterprise: DSM

As the world's leading producer of high-temperature nylon (PA46), DSM has the world's only industrial plan for butanediamine. Butanediamine is the key raw material for PA46 synthesis, which makes DSM take the lead in developing pa4t products. This first new polymer in the 21st century has excellent space stability, lead-free welding compatibility, high melting point, high hardness and mechanical strength when the temperature is rising. Compared with the original product of DSM, PA46 or even PA9T, it shows ultra-low water absorption. Pa4t, with its comprehensive and excellent performance, will occupy an important share in high temperature applications such as electronics, electronics and automobiles in the future. The invention of pa4t is also the embodiment of higher requirements of performance materials for market miniaturization and electronic product centralization.

The representative enterprise of Nylon 6T : Mitsui chemical

Arlen Is a high temperature resistant nylon developed by Mitsui chemical company of Japan. It is a modified nylon 6T based on terephthalic acid, adipic acid and hexanediamine. Its melting point is as high as 310 ℃. Arlen? Is a modified nylon 6T based on terephthalic acid, adipic acid and hexanediamine. Its melting point is up to 310 ℃. Arlen is characterized by excellent high temperature rigidity, dimensional stability and chemical resistance. Due to its excellent characteristics, Arlen has been widely used in many fields, including automotive parts, mechanical parts and electrical / electronic parts. Arlen has a wide range of applications in many fields, including automotive parts, mechanical parts and electrical / electronic parts. Arlen is a heat-resistant nylon developed by Mitsui Chemicals, Inc. in Japan, which is especially suitable for electronic connectors for SMT.

The representative enterprise of Nylon 9t : Japan Cola Co., Ltd.

PA9T was first developed and industrialized by Kuraray. The trade name is genestar, which is obtained by the polymerization of p-phenylenediacid with straight chain aliphatic diamide with carbon number of 9. Genestar's water absorption is 1 / 10 of PA46, 1 / 3 of PA6T, and the lowest among all kinds of polyamides, which has greatly changed the concept of nylon as water-absorbing plastic. In the practical evaluation of multi-purpose, it will not cause the size change, physical property decrease, expansion and foaming caused by water absorption, and has a safer stability in high temperature environment. Therefore, PA9T, as a rising star, has shown strong market potential as soon as it is launched, and its initial consumption is in the scale of thousands of tons. With the development of other markets, the increase of consumption and the decrease of cost, the automobile industry will become another main market.

The representative enterprise of Nylon 10t : golden hair technology

Cao Ming, Zhang Mingqiu and so on in our country have carried out systematic research on the synthesis and copolymerization modification of pa10t. The results show that the pure pa10t has a high melting point of 319.1 ℃, and its excellent heat resistance makes pa10t show potential commercial value. China's leading plastic modification enterprise, blonde technology, commercialized the technology. At the rubber and plastic exhibition in 2009, Jinfa company solemnly launched the pa10t product with the brand of vicnyl, which has excellent heat resistance, ultra-low water absorption, better dimensional stability, resistance to lead-free solder temperature up to 280 ℃, excellent chemical resistance and injection molding performance. Moreover, it is said that nearly half of the raw materials of pa10t resin come from castor, which belongs to bio based environmental protection materials. The excellent comprehensive performance shows a strong market competitiveness. The commercialization of pa10t products has filled in the blank of independent research and development of high temperature nylon new materials in China, and Jinfa company has become the second domestic unit with high temperature nylon industrial technology after Shanghai jieshijie company.
