Ethafoam® AS 220 is an anti-static packaging foam with a closed-cell structure and a density of 37kg/m³ (2.2 pcf).
The anti-static properties of Ethafoam® AS 220 make it better suited than standard grades for protecting electrostatic-sensitive components (ESD) like electronics, computers, and medical equipment from damage from static discharge during transit. Along with its built-in electrostatic dissipation, it retains the high load-bearing capacity and multi-drop protection of the standard Ethafoam 220 grade, while also offering compliance with EIA 541 requirements for static decay and surface resistance.
Polyformes is the UK’s leading foam expert and an official Sealed Air partner. We can supply Ethafoam® in the exact size you need, pre-fabricated packaging and products, and we are happy to provide impartial advice on the best material for your requirements.
The data presented for Ethafoam® AS 220 relates to the unfabricated polyethylene foam product with anti-static properties. While values shown are typical of this product, they should not be construed as specification limits. These are given to the best of our knowledge and should be considered as guidance for selecting a suitable grade for a given application.
