Abstract
In continuous extrusion of polyurethane raw materials plus additives with or without fillers, the metered raw materials are fed to a mixing zone and then extruded. After the mixing process, the material is allowed to dwell to raise its viscosity. Numerous types of resin systems, catalysts, stabilisers plasticisers, emulsifiers flame retardants fillers etc. can be used, process has thermal control to suit the system used.
