What are high and low density polythenes ? |
| Answer» Solution :High DENSITY polythene is obtained by coordination polymerization while LOW density polythene is obtained by free radical polymerization. High density polythene has linear structure while low density polythene than low density polythene. Therefore, high density polythene has greater toughness, hardness and tensile strength household PIPES, etc. while low density polythene is mainly used as a packaging material (in form of thin films and bags). as insulation for electrical wires and cables and ALSO for the manufacture of flexible pipes and SQUEEZE bottles. | |
