Polypropylene (PP) Structure Sexuality Very light plastic with a density of only 0.9g/cm3 Processing properties without preheating and drying Advantage 1. Easy to dye 2. Good moisture resistance 3. Good chemical resistance 4. High hinge characteristics 5. Impact resistance Deficiency 1. Complex aliens are not easy to squeeze 2. Easily decomposed by ultraviolet rays 3. Not ea
PP is polypropylene, which can be divided into isotactic polypropylene, syndiotactic polypropylene, Zhi random polypropylene, propylene ethylene random copolymer, propylene ethylene block copolymer, grafted polypropylene, chlorinated polypropylene, metallocene polypropylene and so on. It can be divided into extrusion stage, drawing stage, coating stage, injection stage, film stage and so on. PE i
4 major uses of PP plastic particles Do you know what pp plastic particles are? Today I will give you a detailed introduction to the characteristics and uses of pp plastic particles. PP plastic particles are non-toxic, odorless and tasteless milky white crystalline polymers with high crystallinity and regular structure. With its excellent characteristics and wide range of applications, its appl
The common problem in the production of pp plastic particles is that the particles are more than twice the normal. At this time, the process needs to be adjusted. Pay attention to the inspection of the pelletized motorized knife and replace the damaged movable knife in time. For the long strips, a suitable vibrating screen can be used for sieving. . Sometimes there will be two or more pp plastic

11 common faults and solutions for PVC, PP, PE extruders Before introducing the common faults of the extruder, let's first understand what is a plastic extruder? Plastic extruders are divided into twin-screw extruders and single-screw extruders, as well as multi-screw extruders and screwless extruders that are not commonly seen. Extrusion systems include screws, barrels, hoppers, heads, and
Common Problems and Solutions in the Granulation of Five Modified Plastic Particles 1. Break 1. The raw materials have miscellaneous materials. Check whether the materials in the material opening contain miscellaneous materials. 2. Poor plasticization, the processing temperature needs to be increased. (For glass fiber reinforced composite materials, it is often caused by exces
Common problems and solutions of plastic granulator Common problems and solutions to plastic granulators: when the plastic granulator unit is in use, the friction clutch is disengaged, the unit is interlocked, and the price of the polypropylene granulator is caused by the frequent occurrence of such failures: the main motor The main motor torque of the system is too high or too low; the frictio
