PP is a commonly used plastic product raw material for edge booster spray bottles, but do you really know this material? This substance has a relatively smooth surface and can replace some other plastics. The smooth surface also makes it difficult to bond PP to other surfaces, that is, PP cannot be firmly bonded with industrial glue, and sometimes welding must be used for bonding. PP also has a low density compared to other plastics, which saves weight for the user. PP has excellent resistance to organic solvents such as grease at room temperature. But PP is easy to oxidize at high temperatures.

    One of the main advantages of PP is its excellent processability, which can be formed by injection molding or CNC machining. For example, PP medicine box, the lid is connected to the bottle body through a living hinge. The medicine box can be directly processed by injection molding or CNC. The living hinge that connects the lid is a very thin piece of plastic that can be bent repeatedly (with an extreme range of motion close to 360 degrees) without breaking. Although the living hinge made of PP cannot bear the load, it is very suitable for the bottle cap of daily necessities.

    Another advantage of PP is that it can be easily copolymerized with other polymers (such as PE) to form composite plastics. The copolymer significantly changes the properties of the material, enabling stronger engineering applications compared to pure PP.

    Another immeasurable application is that PP can act as both a plastic material and a fiber material. The above properties mean that PP can be used in a variety of applications: plates, trays, cups, tote bags, opaque plastic containers, and many toys, etc.
