I made of plastic raw materials accessories containing benzene, how to remove the teacher, please enlighten!
Plastic generally does not contain benzene, ah, only polystyrene, ABS and other plastic molecular structure containing benzene ring, is a high polymer. Benzene is an organic solvent, low molecular substances, boiling point is low, very volatile.
Benzene is generally not used as a plastic processing aid, even if mixed with a little, the plastic molding process in the high temperature also make it has long been volatile.
The use of benzene: fats, resins and iodine and other solvents. Determination of mineral refractive index. Organic synthesis. Optically pure solvent. High pressure liquid chromatography is used as solvent, synthetic dyes, pharmaceuticals, pesticides, petroleum and chemical products, photographic materials, varnishes, nitrocellulose lacquer thinners, paint remover, lubricating oil, grease, wax, Sai Luluo, resin, artificial leather and other solvents. It must be the raw material you bought that contains some other additives. Benzene is not removed
