LDPE, the first of the polyethylenes to be developed, has good toughness, flexibility, low-temperature impact resistance, clarity in film form, and relatively low heat resistance. Like the higher-density grades, LDPE has good resistance to chemical attack. ...

Polyethylene structure has been investigated by energy dispersive Xray diffraction (EDXD) as a function of temperature below the melting point, via Rietveld refinement. The behavior was studied at four temperatures, namely 25, 40, 70, and 88°C. In this range the structure undergoes a regular ...

(1%, compared with 5–6% forKevlar49).Because of its very lowcoefficient of frictionand it is self-lubricating, it can also be used in artificial joints. The melting point ofUHMWPEfibers is 147°C, and application temperature is limited to 80–90°C. UHMWPE fibers provide high impact ...
Polyethylene-polypropylene glycolgenerally occur as white, waxy, free-flowing prilled granules, or as cast solids. They are practically odorless and tasteless. At room temperature, poloxamer 124 occurs as a colorless liquid. Originator Polykol ,Upjohn, US ,1958 ...

The crystallization of polyethylene has been shown to be independent of the previous temperature of melting, even when the melting point is exceeded by as little as 0路3掳C. The persistence of nuclei which are progressively removed as the temperature is raised above the melting point is thus ...
