Webb1 jan. 1989 · The thermo-oxidative stability of high density polyethylene was studied using multiple extrusions. Unstabilized Phillips HDPE (Cr-catalyst) showed a tendency towards crosslinking whereas unstabilized Ziegler HDPE (Ticatalyst) favoured chain scission. The molecular weight distribution and polydispersity of the polymers changed during … WebbEl polietileno de alta densidad (HDPE) es un polímero o plástico de cadena larga. El polietileno es la forma más común de plástico en el mundo y se puede procesar de varias maneras para hacerlo más delgado, flexible, esponjoso o fuerte y duro, como con HDPE. WebbThe Plant for production of high density polyethylene - HDPE, started in 1975. It is based on the process technology Phillips Petroleum Co(today-Chevron Phillips Chemical Company-USA), and it was constructed according to the project Crawford & Russell (USA). Trade name of HDPE is HIPLEX®. greatness collective
