Abstract:
Continuous lamination of ABS and polymethylmethacrylate (PMMA) is achieved employing a continuous sheet or reel of PMMA 0.1 inch to 0.250 inch thick optionally preheated on one side; a web of ABS is extruded at about 450 DEG -550 DEG F. from pellets onto the PMMA at the nip of a roll stack.
