How to distinguish the authenticity of PET plastic?
The method for distinguishing the authenticity of PET plastics is as follows:
1. Brushing, when you burn, pull the wire on the lighter, see if the wire is not long, then pull the pulled wire off, look at the break point in the middle, whether the wire is rolled into a small circle, the more the volume More indicates that the melting point is high. However, if it is a bottle, it should not be a big problem.
2. First taste, PET plastic taste is different from ordinary plastic, burn with a lighter, pure PET plastic will emit a very aromatic taste, if the PET plastic contains other ingredients, the taste is very pungent. There is a bottle containing SEBS ingredients that cannot be used.
3. Look at the burnt part. If the black or oil droplets are distributed quickly, most of the melting points are not normal, which is often found in PET plastic film sheets.
4. The most critical point is to distinguish whether it contains PET plastic, which is a fatal injury to PET. First sample more, then tiling in a sunny place, PVC is light blue in the sun. If there is a white crease in the fold. The above is the naked eye identification, the accuracy is limited, mainly depends on experience.
