Document Summary
There are 3 ways to join plastic materials. Chemical bonds-using chemical adhesives and solvents to join plastic parts. Thermo bonding-use heat to fuse together plastic parts. The two main types are friction and applied heat. Mechanical bonds-using physical attachments to bond plastics together. Adhesive bonding-plastic parts and shapes may be bonded to one another as well as to dissimilar materials using a widely available range or commercial adhesives. Because adhesive bonding involves the application of chemically different substances between two parts, the end use environment of the assembled unit is of major importance. Operating temperatures, environments, unit shape, and production volumes must be considered. Epoxy and acrylic adhesives are recommended because of their versatile properties and fast cure rates. Solvent bonding (welding)-involves a chemical agent dissolving the outer skin of a resin sufficiently to allow it to be joined with other compatible parts. After the solvent has been evaporated, a true bond is created with no intermediate material.
