Weldable thermoplastic resins can be categorized as amorphous or crystalline. Weldable AMORPHOUS resins include: polycarbonate, polyphenylene oxide, polystyrene, ABS, polyetherimide, acrylic, and polysulfone. Weldable CRYSTALLINE materials include: thermoplastic polyester, nylon, acetal, polyethylene, polyphenylene sulfide, and polypropylene. Yes, a limited number of dissimilar, amorphous thermoplastics can be welded together (e.g., ABS and polycarbonate). Melt temperature difference for dissimilar materials can’t be greater than 50° F.
