Differentiation of waste plastics

LDPE (Chinese name: low density high pressure polyethylene):
Sensory identification: soft to the touch: white and transparent, but transparent, often tape and printing. (Note: tapes and printed words are unavoidable, but their content must be controlled as these will affect the prices in the market)
Identification of combustion: burning flame on the yellow under blue; burning smoke, there is the smell of paraffin, melting dripping, easy drawing.

EVA (Chinese name: Polyethyl-ethyl acetate):
Sensory identification: surface soft; stretch toughness stronger than LDPE, feel sticky (but no glue on the surface); white transparent, high transparency, feel and feel very similar to the PVC film should pay attention to distinguish.
Identification of combustion: When burning, the odor of paraffin like LDPE is slightly sour; burning flame is yellow and blue; smoke is no smoke when burning. Molten dripping, easy to pull.
Note: This product is a kind of PE, the same price with LDPE, can be used for regeneration granulation, quality requirements and PE the same.

PP (polypropylene):
Sensory identification: This product is white transparent and has a higher transparency than LDPE and sounds when rubbed.
Identification of combustion: When the flame is burned, the flame is yellow and blue, the smell is like oil, and the molten drips. When burning, there is no black smoke.

PET film (polyurethane)
Sensory identification: This product is white transparent, feel hard, sound when rubbing. Appearance like PP.
Identification of burning: When burning, there is black smoke, and the flame has a phenomenon of flashover. After burning, the surface of the material is black carbonized, and the finger rubs the black charred material after burning, and the carbide is powdery.

PVC film (PVC)
Sensory identification: looks very similar to EVA but elastic.
Identification of combustion: Black smoke when burning, away from the fire, the burning surface is black, no melting dripping phenomenon.

Nylon copolymer (LDPE + nylon):
Sensory identification: This product is very similar to LDPE.
Burning identification: burning flame yellow blue, burning smoke-free, paraffin odor, melting dripping, easy to draw but different from the LDPE is burning when the hair burning smell, pale yellow after burning.
Note: Nylon copolymers can not be used for regeneration and granulation. Strict control of LDPE must be strictly controlled in large parts.

Sensory identification of PE+PP copolymers: Compared with LDPE, this product is much more transparent than LDPE, and there is no difference in feel between LDPE and LDPE. The tear test is very similar to PP film, and the quality is transparent and white.
Identification of combustion: When the product is burned, the flame is all yellow, melted and dripping, no black smoke, and the smell is like oil.

PP + PET copolymers sensory identification: appearance like PP, transparency is very high, the sound when rubbing is greater than PP.
Identification of combustion: When burning, there is black smoke, the flame has a phenomenon of flashover, and the burning surface is charred black.

Sensory identification of PE+PET composite film: The surface of the material is not smooth on one side and white and transparent.
Identification of combustion: when burned like PET, no melting dripping phenomenon, the burning surface is black charred, there is black smoke, there is a flashover phenomenon, with a paraffin odor of PE.
