How does the price of PVC compare to polyethylene and polypropylene?

When comparing the prices of PVC (polyvinyl chloride), polyethylene, and polypropylene, it's essential to consider factors such as raw material costs, production processes, and market demand. PVC is generally more affordable than polyethylene and polypropylene due to its simpler manufacturing process and widespread availability. Polyethylene, particularly high-density polyethylene (HDPE), tends to be more expensive than PVC but offers superior durability and chemical resistance. Polypropylene, known for its versatility and high melting point, often falls between PVC and polyethylene in terms of cost. However, prices can fluctuate based on global oil prices, as these plastics are petroleum-derived. Ultimately, the choice between these materials depends on the specific application and budget constraints.
