Abstract
The use is investigated of polymeric microballoons in place of glass microballoons for the manufacture of polyethylene syntactic foams. Whilst glass microballoons have good mechanical and thermal properties, they are subject to breaking and shearing during processing. This present study deals with the viscoelastic properties of extruded PE and a foam made from PE and approximately 40 volume percent of polymer microballoons. Results are discussed of creep tests and stress relaxation tests. 6 refs.
