PP pipe plugs and stoppers are pipe accessories manufactured from polypropylene (PP). They feature chemical corrosion resistance, lightweight construction, impact resistance, and low cost, making them widely used in industrial piping, home repairs, equipment protection, and other applications. PP material exhibits chemical corrosion resistance, demonstrating excellent resistance to acids, alkalis, salts, and most organic solvents, making it suitable for chemical pipelines, laboratory equipment, and similar applications. With a density of only 0.9-0.91 g/cm³, PP is approximately 40% lighter than ABS while offering good toughness and resistance to deformation from impacts. PP raw material costs less than ABS, making it ideal for budget-sensitive projects. Additionally, it is recyclable and renewable, aligning with environmental sustainability trends. PP plugs typically operate within a temperature range of -20°C to 120°C, with some variants offering high-temperature resistance up to 110°C, meeting most industrial requirements. These plugs primarily seal pipe openings to prevent dust and moisture ingress, safeguarding internal materials such as lithium battery separators and optical films. During lithium battery separator transportation, the plugs provide airtight sealing and dust protection, maintaining material cleanliness and extending service life.
