Meaning and Definition
A lightweight, cellular material manufactured by introducing gas bubbles into a plastic base during production.
A broad class of synthetic, lightweight, porous materials with uses ranging from insulation and packaging to cushioning and flotation devices. It is characterized by its low density, thermal and acoustic insulation properties, and buoyancy.
Dialectal Variation
British vs American Usage
Differences
The term is used in both varieties, but British English may marginally favour 'expanded polystyrene' (EPS) for specific types, especially in consumer contexts. 'Styrofoam' (a brand name) is more common in American English for polystyrene foam cups and packaging.
Connotations
Neutral in technical contexts. Can have negative connotations related to environmental concerns (non-biodegradable waste) in both varieties.
Frequency
Higher frequency in technical, manufacturing, and construction registers. Relatively low frequency in everyday conversation, where simpler terms like 'polystyrene,' 'packaging foam,' or brand names are used.
