ABS/ACRYLIC LAMINATION PROCESS |
摘要 |
Continuous lamination of ABS and polymethyl-methacrylate (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 450-550.degree.F from pellets onto the PMMA at the nip of a roll stack. In the roll stack, the two laminated layers are compressed and gradually cooled. The laminate displays properties of both ABS and acrylic. It has excellent thermoforming properties.
