PP, a high-performance resin that has attracted significant attention in the field of materials science.

　　PP, also known as Polypropylene, is a high-performance resin that has attracted considerable attention in materials science. As another excellent resin variety that has been widely studied and applied after nylon, polypropylene occupies a pivotal position in industrial production and daily life due to its unique physical and chemical properties. It is a high-density, linear polymer with no side chains and high crystallinity. This structure gives it excellent mechanical properties and thermal stability.

　　As a semi-transparent, semi-crystalline thermoplastic, the crystallinity of polypropylene has a crucial impact on its properties. According to the crystallinity, PP can be divided into two major categories: isotactic PP and atactic PP. Isotactic polypropylene, with its ordered molecular arrangement and higher crystallinity, has become a commonly used PP raw material. This material not only has high strength, high modulus and other mechanical properties, but also exhibits excellent heat resistance and chemical corrosion resistance.

　　Polypropylene has excellent comprehensive performance. It has good insulation properties, meaning that in electrical applications, it can effectively prevent current from passing through, ensuring safe operation of the equipment. At the same time, polypropylene has an extremely low water absorption rate, meaning that it can maintain stable performance in humid environments and is not prone to deformation or degradation. In addition, the heat distortion temperature of polypropylene is high, and it can withstand higher temperatures without deformation, making it suitable for use in high-temperature environments.

　　Low density and high crystallinity are another major characteristic of polypropylene. This allows polypropylene products to maintain high strength and rigidity while also having a lighter weight, making them easy to carry and transport. At the same time, high crystallinity also gives polypropylene excellent wear resistance and corrosion resistance, allowing it to maintain stable performance in various harsh environments.
