Plastazote® Plastazote LD33, with a density of 33kg/m3, is one of the most popular and commonly used Plastazote grades.
Plastazote® LD33 provides superb multi-drop shock protection, physical toughness, and excellent thermoforming capabilities. It is selected over lighter grades (like LD24) when long-term durability and structural rigidity are required, but it is preferred over heavier grades (like LD45) to avoid adding unnecessary weight and expense. It is an industry standard for high-end flight case inserts, orthopaedic shoe insoles, and professional sports body armour.
At Polyformes, we are proud to be among the first Zotefoams-approved fabricators in the UK. In short, this allows you to source any Zotefoams material, alongside custom products, tailored precisely to your requirements, etc.
