Natural polypropylene granule

PP stands for Polypropylene, which is a thermoplastic polymer that is widely used in a variety of applications. It is a versatile material that has good chemical resistance, high stiffness, and good processing properties.
PP is produced by the polymerization of propylene monomer using a variety of techniques, such as gas-phase polymerization, bulk polymerization, or solution polymerization. The resulting material is a tough, rigid, and lightweight polymer that can be easily molded and shaped.
One of the main advantages of PP is its excellent chemical resistance, which makes it an ideal material for applications that require good resistance to acids, bases, and organic solvents. PP is also resistant to fatigue, impact, and stress cracking, which makes it an ideal material for products that require durability and toughness.
PP is easy to process and can be molded into a variety of shapes and sizes using injection molding, extrusion, and blow molding techniques. PP can also be easily colored and finished with a range of coatings and textures.
PP has a relatively low cost compared to some other thermoplastics, such as polycarbonate or nylon.
However, PP has some limitations, such as its poor resistance to UV radiation and its low thermal stability. PP can also be prone to deformation under prolonged exposure to high temperatures, which can limit its use in some applications.
Overall, PP is a versatile and widely used material with many useful properties, particularly in applications that require good chemical resistance, stiffness, and toughness at an affordable price point.
