Plastazote
Pronunciation: PLAS-ta-zote
A brand name for a cross-linked polyethylene foam widely used in orthotics as a conformable, heat-mouldable, pressure-distributing lining or insole material.
Full Definition
Plastazote is a trademarked closed-cell polyethylene foam manufactured by Zotefoams plc that is valued in orthotics for its ability to be heat-moulded directly to the patient's foot, its low density, and its excellent pressure-distribution properties. It is available in varying densities (e.g., Plastazote 45, Plastazote 60) that determine its firmness and durability. In editorial documents, 'Plastazote' must always be capitalised as a proper noun; using it in lowercase is a style error. When used generically to refer to any cross-linked PE foam, editors should note this and offer the generic alternative 'cross-linked polyethylene foam.' It is frequently combined with denser foams such as PPT or Poron in multi-layer insole constructions.
Usage
Usage note: Always capitalise 'Plastazote' as a brand name. If generic foam is intended, use 'cross-linked polyethylene foam.' Density grade (e.g., 45 kg/m³) should be stated in fabrication documents.
