Product molecular structure

 

Chemical Properties

Chemical and physical properties are markedly affected by increasing density, which is affected by the shape and spacing of the molecular chain. Low-density materials have highly branched and widely spaced chains, whereas high-density materials have comparatively straight and closely aligned chains. Low-density polyethylene (0.9260.9409 g/cm3) is soluble in organic solvents at temperatures higher than 200°F. It is insoluble at room temperature. High-density polyethylene (0.0410.965 g/cm3) is hydrophobic, permeable to gas, and has high electrical resistivity.
Low molecular weight polyethylenes have excellent electrical resistance and resistance to water and to most chemicals. Medium molecular weight polymers are waxes miscible with paraffin wax, and polyethylene polymers whose molecular weights are higher than 10,000 are the familiar tough and strong resins that are flexible or stiff. By varying the catalyst and methods of polymerization, properties such as density, crystallinity, molecular weight, and polydispersity can be regulated over wide ranges. Polymers with densities ranging from approximately 0.910 to 0.925 g/cm3 are low-density polyethylenes; those with densities ranging from 0.926 to 0.940 g/cm3 are medium-density polyethylenes; and those with densities ranging from 0.941 to 0.965 g/cm3 and higher are high-density polyethylenes.

 

Application:

Polyethylene (PE) is a thermoplastic polymer consisting of long hydrocarbon chains. PE is used in a number of applications including flexible film packaging produced by the blown film process. Polyethylene is used to regulate viscosity, suspension properties, and general stability in cosmetic formulations. Typical applications included specialty injection molded parts, in these fields Polyethylene has a wide range of uses:
Injection and blow molded toys, housewares and lids.
Injection molded car seats, mower parts and pails.
Injection molded, thin-walled containers and housewares.
Hot melt coating for paper, additive in cast moldings, candles, oil-based inks and hot melt adhesives.
Additive to unsaturated polyesters, epoxides and other polymers to impart the unique properties of UHMWPE. Used in industrial parts, coatings and wear surfaces at 10-40 wt. %.
Film applications having good drawdown and toughness.
Mold release additive, lubricant in rubber processing, extrusion and calendering aid for PVC and dispersing aid for color concentrates.
Bearings, gears, bushings and other moving parts.
Laboratory tubing; in making prostheses; electrical insulation; packaging materials; kitchenware; tank and pipe linings; paper coatings; textile stiffeners.
polyethylene is used to regulate viscosity, suspension properties, and general stability in cosmetic formulations. It is derived from petroleum gas or dehydration of alcohol.
