polyethylene

Even paints that stick to most plastics don’t grip to everything, especially polyethylene.

Taking apart polyethylene molecules, for instance, requires temperatures over 400° Celsius.

Stirring the film into a toluene solvent first dissolved the polyethylene layer.

Those alternating segments latch onto plastic molecules of the same kind in a mixture, bringing polyethylene and polypropylene together.

In a second test, the researchers mixed the compatibilizer into a melted blend of polyethylene and polypropylene.

These substances are relatively harmless compared to longer-living man-made plastics like polyethylene.

You seal each sample in a tiny polyethylene bag about ½ inch square.

No, I haven't; we have some rugs, most of them are wrapped in polyethylene.

Specimens were stored in glycerin in glass shell vials having polyethylene stoppers.
