Plastazote® LD45 FR provides the benefits and density (45kg/m3) of LD45, but with flame-retardant performance.
Plastazote® LD45 FR is a tough, high-load-bearing material manufactured with advanced flame-retardant chemicals. It is specified over standard LD45 to meet stringent fire safety standards, and chosen over lighter FR grades (like LD24 FR) when the application involves supporting significant weight or coping with harsh mechanical wear. It is typically found in aerospace flight-deck padding, public transit seating substrates, and protective enclosures for industrial electronics.
Our expertise at Polyformes, alongside close working relationships with Zotefoams® and other material suppliers, enables us to supply and provide technical advice on flame-retardant and other specialist foam materials.
The values provided in this product information represent data gathered from random samples of Zotefoam’s production of Plastazote® LD45 FR foam and represent typical data. These are given to the best of our knowledge and should be considered as guidance for selecting a suitable grade for a given application. Please contact our foam experts for further advice if required.
