大型部品のブロー成形用架橋ポリエチレン樹脂
Document Type and Number:
Japanese Patent JP2010514596
Kind Code:
A
Abstract:
The invention relates generally to the production of polyethylene, and particularly to the production of polyethylene that is mixed with peroxides during extrusion to increase the level of long-chain branching. In an aspect, the polyethylene is used for large part blow molding (LPBM) applications. In an embodiment, the cross-linked polyethylene has a density of from about 0.945 g/cc to about 0.965 g/cc, a molecular weight distribution (MWD) of at least from 10 to 25, for example, and a high load melt index (HLMI) (ASTM D1238 21.6 kg) of from about 1 dg/min to about 30 dg/min. In an embodiment, the cross-linked polyethylene is comprised of at least one olefin having an ESCR of 100 hours to 1000 hours, and a flexural modulus of 120,000 psi to 250,000 psi.
