塑料特性.（Plastic properties.）.doc 塑料特性.（Plastic properties.） Lightweight plastic is a lighter material with a relative density of 0.90 to 2.2. Obviously, can plastic float to the surface? Especially foamed plastics, because there are micropores, the texture is lighter, the relative density is only 0.01. This feature enables plastics
