polyethylene

 [pol″e-eth´ĭ-lēn]
polymerized ethylene, (—CH2—CH2—)n, a synthetic plastic material, forms of which have been used in reparative surgery.
polyethylene glycol a polymer of ethylene oxide and water, available in liquid form (polyethylene glycol 300 or 400) or as waxy solids (polyethylene glycol 1540 or 4000), used in various pharmaceutical preparations as a water-soluble ointment base. Polyethylene glycol is also used as a laxative.

polyethylene glycol  (PEG) a generic name for mixtures of condensation polymers of ethylene oxide and water, available in liquid form (polymers with average molecular weights between 200 and 700) or as waxy solids (average molecular weights above 1000); some are used as pharmaceutic aids, and p. glycol 3350 is used as a laxative.

polyethylene

[pol′ē·eth′ilēn]
a strong but flexible synthetic resin produced by the polymerization of ethylene. Polyethylene materials have been used in surgery.

Plastazote

thermoplastic expanded polyethylene plastic with good insulating properties, formed as heat-mouldable sheets in a variety of thicknesses (e.g. 2-25mm), and varying densities (e.g. soft and hard); used to make moulded orthoses Table 1

polyethylene glycol electrolyte solution
an osmotic solution used as a cathartic to empty the bowel in preparation for endoscopy. Abbreviated PEG. Called also GoLYTLEY.
polyethylene suture
one of the better monofilament fibers because of its good handling, low capillarity, high tensile strength and longevity in tissue. It has only moderate knot-holding capacity.
