3D Printing Filament HDPE Polyethylene Printer Material High DensityToughness Heat Cold Resistance Rigidity mechanical strength

High density polyethylene (HDPE) is a kind of tree plastic resin with high crystallinity and non polarity. The appearance of original HDPE is milky white, and it is translucent to a certain extent in the thin section. PE has excellent resistance to most domestic and industrial chemicals

HDPE is a high crystallinity, non-polar thermoplastic resin. HDPE is non-toxic, tasteless and odorless white particles with melting point of 130 "C and relative density of 0.941-0.96.It has good heat resistance and cold resistance, good chemical stability, high rigidity and toughness, and good mechanical strength. Dielectric properties and environmental stress cracking resistance are also good. The melting temperature is 120 ~ 160 ° C. For the materials with large molecules, it is suggested that the melting temperature should be between 200 ^ 250 ° C. High density polyethylene (HDPE) is a kind of white powder granular product, non-toxic, tasteless, density in the range of 0.940 ~ 0.976 g / cm3; crystallinity is 80% 90%, softening point is 125 ~ 135 ° C, service temperature can reach 100 ° C; hardness, tensile strength and creep are better than low density polyethylene; wear resistance, electrical insulation, toughness and cold resistance are better, but slightly worse than low density polyethylene; The film has good chemical stability, insoluble in any organic solvent at room temperature, and resistant to corrosion of acid, alkali and various salts; The aging resistance is poor, and the environmental cracking resistance is not as good as that of LDPE, especially the thermal oxidation will reduce its performance. Therefore, antioxidant and ultraviolet absorbent should be added to improve the resin. The hot deformation temperature of HDPE film under stress is low, which should be paid attention to in application.
