Plastazote
Pronunciation: plas-tuh-zote
A proprietary cross-linked polyethylene foam used in orthotic fabrication, valued for its heat-mouldability and pressure-relieving properties.
Full Definition
Plastazote is a brand name for expanded, cross-linked polyethylene foam manufactured in several density grades (typically designated by number, e.g., Plastazote LD45). It is widely used in diabetic footwear and accommodative orthotics because it moulds readily at relatively low temperatures, conforms closely to bony prominences, and provides effective pressure redistribution. Editors should note that Plastazote is a proper noun and trade name and must be capitalised; it is incorrect to write 'plastazote' in lowercase unless house style dictates otherwise for trade names. The material is distinct from EVA and Poron, which have different compression characteristics and clinical applications.
Usage
Usage note: Always capitalise as a trade name. Do not use generically as a synonym for all polyethylene foams; specify the grade where possible.
