Domestic production of renewable materials are difficult to identify as a lot of plant waste are impure (such as miscellaneous materials, such as ABS, PE, lime content are heavy and lower costs).
Color: Any band penetration is better than the unpenetrated no matter what color they are.
Gloss: The lighter gloss is better than the dark gloss. Luster is the so-called material itself which is like people’s skin color and that is the color of the material surface.
Odor: with lighter ignited 3 seconds after blowing out, it’s the smell of smoke, identify it and the new PP material differences, which should be noted that some of the larger flavor color toner issued mask PP (PP renewable material) part of the flavor, do not worry, there are ways.
Drawing: After blowing the fire, contact with iron objects quickly melt, then quickly opened to see the forming wire is not uniform, the uniform is a good material, after drawing several times, the wire overlap again opened, look at it with or without elastic, can pull again and continue, without interruption or pull back some distance off is good material.
The above can’t be confirmed again by fire, black smoke or melt quickly under rapid drop in the combustion process, which is not a good material.
Teeth: At first, you can experience the new material PP intensity, and then compare, if relatively soft, which absolutely have PE.
Look cutout sections; section rough, dry and dull which is poor material.
Floating: As long as there are submerged, that difference also was not sure and the best way is to test machine. My personal opinion is that no matter good or bad, should be identified through the machine as it is the safest. Other materials may also have the same solution which have to have their own understanding of the new materials. The price is too cheap, the quality will certainly have problems and the actual cost will be cheaper.
