Hdpe material melting temperature

WebLDPE has a slightly lower melting point of about 110 °C as compared to HDPE which melts at around 131 °C (see footnote 1). These low melting points allow for fast injection molding and there is no need for drying the molded part. They are both relatively low weight materials (light weight compared to other materials for objects). WebProprietà. L'HDPE presenta scarse ramificazioni, col risultato che le forze intermolecolari e la resistenza alla trazione sono maggiori che nelle varietà di polietilene meno dense. Le differenze meccaniche sono più rilevanti delle differenze in densità, di modo che l'HDPE possiede una più alta forza specifica. È anche più duro e più opaco e può sopportare …
