The vibration welding of poly(methyl methacrylate) to itself and to polycarbonate, poly(butylene terephthalate), and modified poly(phenylene oxide)
The weldability of poly(methyl methacrylate) (PMMA) to itself and to polycarbonate (PC), poly(butylene terephthalate) (PBT), and modified poly(phenylene oxide) (M-PPO) is assessed through 120 and 250 Hz vibration welds. Weld strengths equal to those of the base resin have been demonstrated in welds of PMMA and M-PPO to themselves. In welds of PMMA to PC and to M-PPO, weld strengths equal to those of PC and M-PPO, respectively, have been demonstrated. PMMA does not weld well to PET; the highest weld strength obtained was 21% of the strength of PET resin.
