Watch Are Plastics Too Strong?

DESACTIVA ADBLOCK PARA VISUALIZAR LA PELICULA

     

The similar chemistry that will make plastic hard, light-weight and flexible also will make it almost extremely hard to get rid of, mainly because it is hard to split all those resilient chemical bonds.

Polymer: A material whose molecular composition is made up of substantial quantities of similar models covalently bonded jointly
Covalent bond: A strong type of bond in which adjacent atoms share electrons.
Backbone chain: A extensive sequence of covalently bonded atoms that develop the continual chain of the molecule.
Bioplastic: A type of plastic, normally biodegradable, manufactured from organic substances.
Scission: The breakage of a backbone chain at the bond stage.
Microbial biodegradation: The use of microbes to split molecules into lesser and less destructive kinds.
