What's the difference between recycled plastic bucket and plastic bucket made of raw material?
The easiest way to do this is to press hard, see flexibility and bounce back. You can also cut off a small piece with a knife, lost in the water, can float is generally the new material is recycled sink. If PE is the plastic bucket, the recycled material is usually porcelain white, and the raw material should be translucent.
What plastic material has great impact resistance?
The ability of metal materials, machinery parts and components to resist impact damage is called impact strength.
Is the plastic with high melting index good?
The melt index, the full melt flow index, or the melt flow index, is a numerical value that indicates the fluidity of the plastic material when it is processed.

What is the material of plastic flat screen?
Plastic flat net (also known as plastic breeding net) is plastic material in the extruder heating melting through the extrusion into a special rotating head is provided with a plurality of holes inside and outside of the die, the molten plastic flowing through the die pore forming two shares melt silk, because of head rotation, two shares converge to a continuous filament thus, the formation of network, after cooling into the net.
How to test plastic raw materials?
Sample appearance quality. The plastic raw material is produced according to the normal production process, and the appearance quality of 10~20 parts is observed. The sample product shall not be cracked, deformed, foamed, broken, expanded or shrunk, and other defects that affect appearance. Smooth surface and clear surface.
