Abstract

We have disclosed the packaging materials with built-in anti-static foam and how to use the foam. The foam used is a polyether polyurethane foam prepared from an isocycled pre-polymer. Anate, a product obtained from the reaction of polyols Lean and polyisocyanate This foam depicts a surface resistance of less than 1 x 10 to a power of 12 ohms / square and the time of decay. Of static electricity for about two seconds or less. Foam that should be used for display The electrostatic decay time is approximately two seconds or less. The foam that should be used represents the electrostatic decay time of 0.1 s or less. Packaging, including those used around static-sensitive equipment or used for Store or transport electrically sensitive equipment.
