The scientific name of PPA plastic is poly (phthalamide). The plastic has excellent strength, toughness, hardness, fatigue resistance and creep resistance. Under continuous high temperature and high humidity
It can also withstand the high temperature of 200, and continue to maintain its good dimensional stability, which can eliminate shark skin. In general, the tensile strength of PPA is 20% higher than that of nylon 6
Nylon 66: In terms of bending modulus, PPA plastic is 20% higher than nylon, so it has greater hardness and elongation. Creep equipment: PPA is more resistant to gasoline, grease and coolant than PA
Strong; PPA can also improve surface finish.
PPA plastic
In applications, PPA is widely used for cables, pipes and fibers. Applications include PE film, BOPP/OPP stretch film, HDPE hollow, PE and PP sheet. In our daily station wagons, auto parts can reduce weight, reduce cost and provide long service life at the moment of fuel, gearbox and engine system. The application of chipsets and sockets as well as cup welding brackets can prevent deformation and strain. Connectors, controllers, sensors, motors and other key electronic components, as well as high-frequency electronic components, can improve the processability of metallocene resin and make full use of its excellent physical properties.
In terms of function, if high strength and high quality films are to be produced, PPA can be used to increase tension and reduce costs. Eliminate the adhesion of cemented carbide on the steel surface of equipment, extend the maintenance cycle of equipment, and maintain the use of equipment. Reduce melt fracture and sharkskin, improve transparency: improve the brightness and smoothness of the product surface, improve the printing quality: significantly reduce the crystal points generated during film processing, thus reducing the crystal points caused by fine printing white spots: eliminate the longitudinal yang force caused by the film surface through the mold or equipment transmission parts; Improve the uniformity and stability of the film thickness, thereby improving its physical properties; Reduce the mold temperature to ensure the stability of film blowing bubbles; Improve pigment coloring, shorten color switching time, and extend continuous production time.
