Eastalite is a foamed copolyester resin. When extruded into sheet, Eastalite can be cut with minimal generation of particulates or angel hair. It can save processing and inspection time, reduce waste and cleaning, and ultimately lower processing costs when compared with HIPS. Eastalite copolyester resin is manufactured—and its use is licensed and supported—by Eastman Chemical Company, a leader in medical polymers and foam technology.
