With a density of 70kg/m³, Plastazote® LD70 is the heaviest-duty material in the LD range.
Plastazote® LD70 closed-cell foam behaves almost as a semi-rigid block, providing unparalleled load-bearing performance, toughness, and durability. It is selected over all lighter grades when components are exceptionally heavy or sharp, or where the foam must survive long-term abrasion and rough environments without eroding. Typical applications include heavy engineering component transport, industrial machinery mounts, and high-load flotation systems.
Regardless of the foam material, packaging or products you require, at Polyformes, we can help. As Zotefoam® approved fabricators, we utilise state-of-the-art in-house conversion equipment to transform sheets of any size into tailored inserts, dunnage, and custom-engineered packaging solutions.
The values provided in this product information represent data gathered from random samples of Zotefoam’s production of Plastazote® LD70 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.
