The editor of Ascendas Engineering Plastics is here to introduce to everyone to prevent things from happening. We can only watch things happen and do nothing. Impacting the plastics industry, surface grafting uses high-energy rays such as ultraviolet rays, γ-rays, plasma, and electron beams to trigger PA66 to generate radicals, and the flame retardant monomers are grafted onto the surface of PA66 fibers or fabrics to form chemical bonds. Ascend’s nylon 66 strives for the needs of various specific applications in the automotive industry. , But the PC/ABS plastic is different. It not only has the obvious ambiguity of PC plastic, but also has the high blackness of PMMA.

Market demand for high melting index PP
The melt flow properties of polypropylene are closely related to its molecular weight. The weight average molecular weight of the commercial polypropylene resin prepared by the conventional Ziegler-Natta catalyst system is generally between 3×105 and 7×105. The melt index of these conventional polypropylene resins is generally low, which limits the scope of application.
With the rapid development of the chemical fiber industry and textile machinery industry, the non-woven fabric industry has risen rapidly. A series of advantages of polypropylene make it a raw material for non-woven fabrics. With the development of society, the application fields of non-woven fabrics tend to be broad: in terms of medical and health, non-woven fabrics can be used to make isolation gowns, surgical gowns, women’s sanitary napkins, baby diapers, etc.; as construction and geotechnical materials, non-woven fabrics Woven fabrics can be used in roof waterproofing, road construction, water conservancy projects, or use spunbond and needle-punched composite technology to produce high-quality roofing felt, and its service life is 5-10 times longer than traditional asphalt felt; filter materials are also developed by non-woven fabrics One of the fastest products, which can be used for gas and liquid filtration in the chemical, pharmaceutical, food and other industries, and has a huge market potential; in addition, in the household, non-woven fabrics can be used for synthetic leather, luggage, clothing lining, decoration Manufacture of cloth and wiping cloth.
It is precisely because of the continuous development of non-woven fabrics that the requirements for its production and applications have also been continuously improved, such as melt blown, high-speed production, and thin products. Therefore, the requirements for the processing performance of the main raw material of non-woven fabrics, polypropylene resin, are also correspondingly improved; in addition, the production of high-speed spinning or fine-denier polypropylene fibers also requires polypropylene resins to have good melt flow properties; some cannot withstand high temperatures Pigments require polypropylene with a relatively low processing temperature as a carrier. All of these require ultra-high melt index polypropylene resins that can be processed at lower temperatures as raw materials.
The special material for melt blown cloth is polypropylene with high melt index. Melt index refers to the mass of the melt through the standard die capillary every 10 minutes. The larger the value, the better the processing fluidity of the material. The higher the melt index of polypropylene, the finer the melt-blown fibers and the better the filterability of the melt-blown cloth.

Among the materials, ぷNuomu salt pressure table ┥⒌ pouring and permeating brittle fibers, ④PA66 has a higher melting point, and the mold temperature should be appropriate. If the mold temperature is too low, the melt will cool too quickly, and the product will have greater internal stress. Ascend announced that its first-tier auto parts suppliers have substantial sales. Despite this, the global sales of Faurecia, a first-tier auto parts supplier, are still rising. Improve the recycling network of renewable resources,

Glass fiber is a strong body widely used in fiber-reinforced composite materials. Engineering plastics are widely used in the production of auto parts and gradually replace metal. 1. Polytetrafluoroethylene PTFE is a coefficient among all additives. No need to plug in, PA66 has good overall performance, high strength, good rigidity, impact resistance, oil and chemical resistance, abrasion resistance and self-resistance, especially the hardness, rigidity, heat resistance and creep properties are better, and the raw material Easy to obtain, low cost, so it is widely used in various fields such as industry, clothing, decoration, engineering plastics and so on.
