The disadvantage of this method is that two operations are performed, one is to implant the stainless steel material, and the other is to remove them. Scientists in Holland have invented a plastic that has been implanted in the body for about two years and then decomposes itself into carbon dioxide and water. There is also a linear biological self destruct plastic that can replace the traditional medical surgical line to suture the wound. This plastic surgical line can be gradually absorbed by the body, eliminating the pain of removing stitches. In addition, a capsule made from self destruct plastic will slowly dissolve in the body and control the speed at which the drug enters the blood vessel. A new type of biological plastics developed in Shanghai. The heat resistance is greatly improved, the heat distortion temperature more than 100 DEG C, and can be widely used for disposable tableware, disposable medical supplies, disposable instruments, electronic devices and other products packaging, and agricultural films, chemical pesticides and fertilizers and other agricultural field release material.s
