Product Description

The main application of PP is the packaging industry, which accounts for about 30% of the total consumption. This is followed by electrical and equipment manufacturing, which consumes about 26%. Household appliances and the automotive industry each consume 10%. The construction industry consumes 5%.

PP has a relatively smooth surface and can replace some other plastic products, such as gears made of POM and foot pads for furniture. The smooth surface also makes it difficult to bond PP to other surfaces, i.e. PP cannot be firmly bonded with industrial glue and must sometimes be bonded by welding. PP also has a low density compared to other plastics, which reduces weight for the user. However, at high temperatures PP is susceptible to oxidation.

One of the main advantages of PP is its excellent processability, which can be molded by injection molding or CNC machining. An example is the PP pill box, where the cap is attached to the bottle by a movable hinge. The pill box can be directly machined by injection molding or CNC machining. The movable hinge that attaches the lid is a very thin piece of plastic that can be bent repeatedly (to an extreme range of motion approaching 360 degrees) without breaking. Although the movable hinge made of PP cannot withstand loads, it is ideally suited for the application of caps on bottles of daily use.

Another advantage of PP, it can be easily combined with other polymers (e.g. PE) in copolymers to form composite plastics. Copolymers significantly change the properties of the material, allowing for more robust engineering applications than pure PP.

Another incalculable application is that PP can act as both a plastic 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.
