NettetCHARACTERIZATION OF INJECTED LINEAR LOW DENSITY POLYETHYLENE (LLDPE) IRRADIATED BY GAMMA-RAY . Ana C. F. Oliveira, Duclerc F. Parra, Hélio F. … NettetSCLAIR polyethylene products are produced in a wide range of densities and can be classified into a broad range of categories including very low, linear low, medium and high-density resins. Very low-density polyethylene (VLDPE) resins are used in the production of high puncture resistant films and sealant layer in multilayer films and pouches.

Notes Nettet29. mai 2012 · Not so with PE. Because of the ability of the material to form either linear or branched structures, the density of polyethylene can vary from a low of 0.857 g/cm3 to a maximum of 0.975 g/cm3. If you held two parts of the same design made from materials representing these two extremes you could readily tell the difference.
Polyethylene was first synthesized by the German chemist Hans von Pechmann, who prepared it by accident in 1898 while investigating diazomethane. When his colleagues Eugen Bamberger and Friedrich Tschirner characterized the white, waxy substance that he had created, they recognized that it contained long −CH2− chains and termed it polymethylene.
