ABS plastic is a kind of plastic with high strength and toughness, which is often used to make automobile parts, electrical housings and so on. Its chemical composition contains acrylonitrile, butadiene and styrene. These substances may release harmful gases at high temperature or high pressure, which may affect human health. In addition, ABS plastics may also contain harmful substances such as benzene, and long-term contact may have a negative impact on the body.
PP plastic is a kind of thermoplastic plastic, which has the characteristics of corrosion resistance, heat resistance, acid and alkali resistance, and is often used to make food containers and drug packaging. Its chemical composition contains propylene and does not contain harmful substances such as benzene. Therefore, compared with ABS plastics, PP plastics are safer, do not produce harmful gases, and have less impact on human health.
