Polyethylene dị obere (LDPE) vs Polymer PTFE/FEP Machining

Polyethylene dị obere (LDPE) bụ thermoplastic emere site na monomer ethylene.Ọ bụ ọkwa mbụ nke polyethylene, nke Imperial Chemical Industries (ICI) mepụtara na 1933 na-eji usoro nrụgide dị elu site na polymerization free radical.Nrụpụta ya na-eji otu ụzọ ahụ eme ihe taa.EPA na-eme atụmatụ na 5.7% nke LDPE (nọmba imegharị ihe 4) ka emegharịrị.N'agbanyeghị asọmpi sitere na polymers ọgbara ọhụrụ, LDPE na-aga n'ihu na-abụ ọkwa plastik dị mkpa.
