Q
is polypropylene a hard plastic
I'm a seasoned industrial engineer with a keen interest in machine learning. Here to share insights on latest industry trends.
Polypropylene (PP) is considered a semi-rigid plastic, being versatile and having a good balance between toughness and flexibility. It's not typically classified as hard like polystyrene or acrylic, but it's stiffer than polyethylene. Polypropylene's characteristics include strong resistance to chemicals, elasticity, and fatigue resistance, making it suitable for various applications including packaging, textiles, automotive parts, and reusable containers. It can be made harder through copolymerization (mixing with another polymer) or by adding fillers. However, in its standard form, it offers a good compromise between pliability and strength, allowing it to withstand considerable wear without breaking.
