Polypropylene (PP) is a type of plastic widely used in various applications due to its resilience and low cost. Being a hydrocarbon polymer, polypropylene can indeed burn. When exposed to flame, it typically melts at around 160°C (320°F) and then ignites, burning with a bright, clean flame, producing water and carbon dioxide as combustion products, along with potentially toxic gases if combustion is incomplete. To mitigate fire hazards, polypropylene can be mixed with flame retardants that increase its resistance to ignition. However, it's essential to implement fire safety practices when handling or storing polypropylene products, especially in environments where open flames or high temperatures are present.

Polypropylene is categorized under the number 5 for plastic coding systems. This identification is part of the Resin Identification Code (RIC), which aids in recycling processes. Polypropylene is known for its stiffness, heat resistance, and serves as a barrier against moisture, grease, and chemicals. Commonly used in packaging, automotive parts, textiles, and reusable containers, it is favored for its versatility and recyclability. This type of plastic is considered safe for food contact, making it a popular choice for containers and kitchenware. However, its environmental impact, like all plastics, includes considerations around its life cycle, from production to disposal or recycling.
