Problems solved by technology

[0003] In recent years, when these resin compositions are discarded without proper treatment, there are controversial problems in that plasticizers and heavy metal stabilizers contained in coating materials are dissolved and eluted, or a large amount of corrosive gas is generated, and dioxins are generated. Wait
In general, a large amount of polypropylene must be contained in order to satisfy heat resistance, but flame retardancy and flexibility may decrease, so improvement is desired
