What are the cost differences between polyethylene, polypropylene, and PVC for large-scale projects?

When selecting materials for large-scale projects, cost is a critical factor. Polyethylene (PE), polypropylene (PP), and polyvinyl chloride (PVC) are three common plastics with distinct price points.

1. Polyethylene (PE): Known for its flexibility and chemical resistance, PE is generally the most affordable option. Its cost ranges from $0.50 to $1.50 per pound, making it ideal for budget-conscious projects like piping and liners.

2. Polypropylene (PP): Slightly more expensive than PE, PP costs between $0.70 and $2.00 per pound. Its higher heat resistance and durability justify the price, especially for industrial applications.

3. PVC: The most expensive of the three, PVC prices range from $0.80 to $2.50 per pound. Its rigidity, flame resistance, and longevity make it a preferred choice for construction and electrical conduits.

Factors like raw material availability, production complexity, and regional demand influence these costs. For large-scale projects, balancing material properties with budget constraints is essential to optimize value.
