Plastic Dictionary

Redwood Plastics distributes engineering plastics and that word “engineering” should tip you off – there is some specialized terminology we use in our literature and articles. Not everything is relevant and some terms are more important than others for our clients, we will outline a few common terms here:epicure-pour

Creep: The slow changing in dimensional stability of a plastic. Especially relevant with polyethylene.

Cross-linking: When valence bonds are formed between polymer chain molecules. In effect, making the material stronger.

Commodity plastic: lower priced, lower performance plastics used for common consumer needs such as point of purchase displays, toys, household containers.

Engineering plastics: higher priced, higher performance plastics used to solve problems for industry. For example, bushings, bearings, wear guides, diverter arms, hopper liners, etc.

Elastomer: A plastic material with rubber-like qualities

Extrusion: A heated plastic is forced through a die

FRP: Fiberglass reinforced plastic. Corrosion-resistant materials used as railings, grating, stairways, etc replacing traditional materials such as steel, aluminum or wood.

Polyurethane: An elastomer with unique physical properties. Can be made anywhere from a soft deadplate to absorb impact, to hard lubrication-impregnated bearing grades.

Thermoplastic: A plastic that can be softened by heat and hardened by cooling in a reversible process.

Thermoset: A Plastic that cannot be reformed after setting.

UHMW-PE: Ultra High Molecular Weight Polyethylene. Perhaps the most popular and widely used engineering plastic.
