ABSTRACT:
Packaging materials containing inherently antistatic foams and a method of using the foams are disclosed. The foam used is a polyether polyurethane foam prepared from an isocyanate containing prepolymer which is the reaction product of a oxyethylene containing polyol and a polyisocyanate. The foams show surface resistivity of less than 1.times.10.sup.12 ohms/square and static decay times of about two seconds or less. A preferred foam shows static decay times of 0.1 seconds or less. The packaging includes articles used around static sensitive devices or used to store or transport static sensitive devices.
