Solvent Cementing of Plastics
Solvent cementing (also solvent bonding or solvent welding) is a process in which thermoplastics, usually amorphous or containing low crystallinity, are softened by the application of a suitable solvent, or a mixture of solvents, and then pressed together to affect a bond. Usually the resin itself, after evaporation of the solvent, acts as the adhesive. Generally, adhesion is achieved by evaporation of the solvent, absorption of the solvent into adjacent material, and/or polymerization of the solvent cement. Many thermoplastic resins are easier to join effectively by solvent cementing than by conventional adhesive bonding. For example, solvent cementing is used to connect plastic pipes such as those made ...
