Engineering plastics developed rapidly in the 1950s. Although nylon 66 resin was successfully developed and put into production as early as 1939, it was mainly used in the manufacture of synthetic fibers. It was not until the 1950s that it broke through the traditional use of pure fibers and was shaped to make plastic. Engineering plastics have really developed rapidly. After the successful development of POM and polycarbonate in the late 1950s, their emergence is of great significance. Due to the high crystallinity of polyoxymethylene, it imparts excellent mechanical properties, and for the first time makes plastics a material that can replace metals and rank among the structural materials. Later, with the successful development of acetal copolymer and the popularity of screw injection molding machines, the important position of engineering plastics in the field of materials was further established. Polycarbonate is a transparent engineering plastic with excellent comprehensive properties. It is widely used and is one of the fastest growing engineering plastics. In the field of engineering plastics, its output and consumption rank second only to polyamide.
2016-2021 China's engineering plastics industry market demand and investment consulting report shows that engineering plastics can be used as engineering materials and plastics instead of metal manufacturing machine parts. Engineering plastics have excellent comprehensive performance, high rigidity, small creep, high mechanical strength, good heat resistance, good electrical insulation, long-term use in harsh chemical and physical environments, and can be used as an alternative structural material for metal. But the price is more expensive and the output is smaller.
This month, the engineering plastics sector has skyrocketed, with PA624.73% and PA666.48%, mainly due to the positive impact of the cost side. After November, the market is like a “dislocated wild horseâ€, and the price has continuously updated to a new high in the year. The most direct cause of this PA6 surge is the strong rise of the pure benzene and caprolactam industrial chain. The caprolactam of PA6 rose by 2,500 yuan / ton in November, an increase of 22%. In contrast, downstream buyers continue to chase after the rise, slice I began to enter the state of "the height is not cold." In the process of this wave of market rise, the impact of market supply and demand fundamentals has been significantly weakened, and the increase in speculative demand has become the biggest driving force to promote the rise of the situation.
It is predicted that the engineering plastics market will continue to operate in a narrow range in December. In particular, this year, engineering plastics such as PA6 and PA66 are completely affected by the cost and are overwhelming. In the absence of fundamental improvement in demand, the future increase will be overdrawn. The big factory also has plans to drive. It is expected that the market supply will increase slowly. However, from the demand side, the operating rates of civil silk, industrial yarn and modified plastics are all low. About 50%, the engineering plastics market may have downside risks. The decline will be between 2-5%.
