Polypropylene vs. Plastic: What's the Difference?

Edited by Aimie Carlson || By Janet White || Published on December 20, 2023
Polypropylene is a specific type of plastic known for its strength and versatility, while plastic is a general term for a wide range of synthetic or semi-synthetic materials.

Key Differences

Polypropylene is a thermoplastic polymer, used in a variety of applications due to its resistance to heat and chemicals. Plastic, a broader category, includes various polymers like polyethylene, PVC, and polypropylene, each with distinct properties.
Polypropylene, characterized by its lightweight and durable nature, is commonly used in packaging, textiles, and automotive parts. Plastics, in general, vary widely in their applications, from household items to high-tech industry components, depending on their specific types.
The manufacturing process of polypropylene involves the polymerization of propylene, resulting in a flexible yet sturdy material. Plastic production, however, can involve different processes like extrusion, molding, and casting, depending on the type of plastic being produced.
Polypropylene is known for being recyclable, contributing to sustainable practices. Plastic as a whole, though, has varying levels of recyclability, with some types being more environmentally friendly than others.
In terms of environmental impact, polypropylene is often favored for its lower degradation rate and less toxic byproducts. Plastic, in general, has raised environmental concerns due to issues like non-biodegradability and pollution.
