Polypropylene (PP) is a versatile thermoplastic polymer known for its excellent chemical resistance, low density, and high melting point. These properties make it ideal for a wide range of applications. In the automotive industry, PP is used for interior and exterior components due to its durability and lightweight nature. In packaging, it is favored for food containers, bottle caps, and films because of its moisture resistance. The construction sector uses PP for pipes and fittings, taking advantage of its strength and corrosion resistance. Additionally, in healthcare, PP is used for medical syringes and laboratory equipment owing to its ability to be sterilized without compromising its properties. The advantages of polypropylene include its low cost, ease of processing, and recyclability. It also offers good fatigue resistance, making it suitable for applications requiring repeated stress. Its versatility and cost-effectiveness make polypropylene a popular choice in various industry
