Plastic itself is non-toxic, because plastics are macromolecular substances, the body can not absorb. Only due to the need to join the processing of toxic additives, or synthetic reaction is not sufficient, the use of small molecules released monomer, the plastic only showed toxicity. So for Linyi plastic chairs, how can we determine whether it has such a volatile toxin?
The characteristics of toxic plastic chair is still very obvious. It is generally more colorful and thick because of the large amount of pigment (organic or inorganic) to be added. But cheaper pigments are poisonous. Followed by impure plastic texture, it is possible to use recycled plastics or other plastics doped, this plastic is no guarantee that its source is safe. Such as medical waste plastics and refuse collection station. Furthermore, when the heat becomes soft, feel sticky hand. Most PVC, the softer, plasticizers and low molecular weight polymers, the general unsafe. Plastic tablecloths do not come into contact with food for a long time, do not touch the food when the temperature is high. Plastic odor, aging plastic replaced, it is safe.
