PP Plastic Rod and PE Polyethylene Plastic Rod are two different types of plastic materials with distinct characteristics and applications. The differences between Pp Plastic Rod and Pe Plastic Rod lie in their density, flexibility, chemical resistance, melting point, and applications. Understanding these distinctions can help determine the most suitable material for specific uses.Here is a description of the difference between them: 1. Composition: PP Plastic rod is composed of propylene monomers, while PE Plastic Rod is composed of ethylene monomers. The difference in monomer composition gives them different properties. 2. Density: PE Plastic has a lower density compared to PP plastic. Generally, the density of PE ranges from 0.91 to 0.96 g/cm³, while the density of PP ranges from 0.89 to 0.91 g/cm³. This density difference results in variations in their physical properties. 3. Flexibility: PE plastic rod exhibits better flexibility and impact resistance compared to PP plastic rod. This makes PE more suitable for applications that require flexibility, such as tubing, gaskets, and seals. 4. Chemical resistance: PP plastic rod has better chemical resistance than PE plastic rod. It is resistant to a wider range of chemicals, solvents, and acids. PE plastic, on the other hand, may not offer the same level of chemical resistance as PP. 5. Melting point: PP plastic has a higher melting point compared to PE plastic. The melting point of PP ranges from 130 to 171°C, while the melting point of PE ranges from 120 to 145°C. The higher melting point of PP makes it more suitable for applications that require higher temperature resistance. 6. Applications: Due to their different properties, PP plastic rod and PE plastic rod find different applications. PP is commonly used in automotive parts, packaging, electrical components, and household products. PE is often used in general-purpose containers, pipes, liners, and agricultural films.
