Extrusion is the second widely used processing technology for PMMA moulding compounds. In this process, the moulding compound pellets are melted and conveyed in a heated barrel containing one or two rotating screws. The melted plastic is pushed through a die or head with the desired shape. Upon exiting the die; the material cools to its final cross-sectional shape. This process is typically used in the manufacture of sheets, films, pipes, tubes, rods and profiles for a variety of applications.
