Zhanjiang Baydur PUL 2500 (81% Glass) PUR-aliphatic/MDI, material report
For example, skating shoes use tough modified nylon 6 as the sole, which is comfortable to wear on the one hand, and is affected by various impact stresses on the other. When the toughening agent AX8900 is added, the interface between the two phases is blurred, but there are still many pores on the fracture surface, but the pore size at this time is small, indicating that the two phases can be partially compatible at this time, and the fracture gradually transitions to ductile fracture. 1. Brief overview: When processing halogen-free flame-retardant nylon, most of the halogen-free flame retardants will not melt, but will directly decompose at a certain high temperature. The main consumer groups of PC alloy are: electrical engineering companies, computer manufacturing companies, office electrical appliances companies, auto parts factories, etc.
Polyvinylidene fluoride
Poly (vinylidene fluoride), the English abbreviation PVDF, mainly refers to vinylidene fluoride
Pvdf molecular formula ethylene homopolymer or copolymer of vinylidene fluoride and other small amount of fluorine-containing vinyl monomers, it has the characteristics of fluororesin and general resin, in addition to good chemical corrosion resistance, high temperature resistance, and oxidation resistance In addition to weather resistance and radiation resistance, it also has special properties such as piezoelectricity, dielectric properties, and thermoelectric properties. It is the second largest product among fluorine-containing plastics, with a global annual production capacity of more than 53,000 tons.
In the chemical structure, a fluorine-carbon bond is used. This structure with short bond properties forms the most stable and strongest bond with hydrogen ions. Therefore, fluorocarbon coatings have specific physical and chemical properties, not only have strong wear resistance and impact resistance, but also have high fading resistance and UV resistance in extremely harsh and harsh environments.

Compared with other materials, the main advantage of modified engineering plastics lies in its good comprehensive performance. A plastic material can have several or even dozens of different properties at the same time. Appeals/a variety of factors will cause low market efficiency, low yield, and product variability. In addition, technically, it is necessary to solve the problem of long-term aging performance. .Schlach was successfully developed and industrialized by the company in 1943. The market volume accounted for 70% of the nylon market. It can be made into high-strength fibers. According to the correct procedures, the waste must be recycled by a qualified professional company. It must be transported to a specific place with a special container and professional transportation tool and then burned at a high temperature above 2000 ℃. Landfill.
Will become no. According to Wang Zhiwei, the drafter of the new national standard and manager of the China National University Group, the higher the cost of materials, the harder to engineer plastic products. These glass fibers are like steel bars in the material that play a supporting role. The bigger, the staff who are familiar with the performance of additives cannot combine well with plastic processing because they are not familiar with plastic modification. 4. Consumption upgrades With the improvement of living standards, so does the spray-free industry. , Heavy resins often added are: PTFE, FEP, PPS and POM, etc.
