Полиэтиленовая Смола высокой плотности HDPE 600 пластиковых гранул которые можно упаковать на складе и поддержать

[Basic characteristics] High-density polyethylene is an opaque white wax-like material with a specific gravity of 0.941~0.960, which is lighter than water. It is soft and tough, but slightly harder than LDPE and slightly elongated. It is non-toxic and tasteless.
[Combustion characteristics] It is flammable and can continue to burn after leaving the fire. The upper end of the flame is yellow and the lower end is blue. It will melt when burning, with liquid dripping and no black smoke. At the same time, it emits the smell of paraffin burning.
[Main advantages] acid and alkali resistance, organic solvent resistance, excellent electrical insulation, and can still maintain a certain degree of toughness at low temperatures. Surface hardness, tensile strength, rigidity and other mechanical strength are higher than LDPE, close to PP, tougher than PP, but the surface finish is not as good as PP.
[Main disadvantages] Poor mechanical properties, poor air permeability, easy to deform, easy to age, easy to become brittle, less brittle than PP, easy to stress cracking, low surface hardness, easy to scratch. Difficult to print, when printing, surface discharge treatment is required, electroplating is not possible, and the surface is matte.
