Polypropylene (PP) is a versatile thermoplastic polymer made up of propylene monomers. It boasts excellent chemical resistance to solvents, bases, and acids, making it less prone to degradation than other plastics. Its durability against fatigue also makes it ideal for products that require frequent bending, including hinges and containers.

Finding the best adhesive for polypropylene can be challenging due to its low surface energy, which makes it inherently difficult for adhesives to bond with. However, cyanoacrylate-based adhesives, also known as super glues, and certain specialized formulations such as 3M's Scotch-Weld Structural Plastic Adhesive DP8005 have been proven effective. These adhesives do not require surface treatment like priming or etching, making them convenient options. DP8005, in particular, is designed for bonding polypropylene and other low surface energy plastics, offering strong, durable bonds suitable for various applications including industrial and household repairs. It's important to follow the manufacturer's instructions for the best results.
