Which cushioning material is the most resistant to cigarette ignition and small flame?

1. Neoprene

2. Cotton

3. Polyester

4. Polyurethane

The correct answer is: Neoprene

Neoprene is the correct choice for its high resistance to cigarette ignition and small flames. This synthetic rubber material is formulated to withstand various forms of heat and wear, making it particularly effective for applications where fire resistance is a priority. Neoprene has inherently flame-retardant properties, which help it resist ignition from cigarettes or open flames, enhancing safety for furniture and other applications where such materials might be present. Cotton, while a natural fiber known for its comfort and affordability, is highly flammable and does not provide the same level of protection against ignition. Similarly, polyester is also flammable but is often treated with flame-retardant chemicals, which can vary significantly in effectiveness. Polyurethane is a versatile foam often used in cushioning; however, it can ignite more easily compared to neoprene and may produce toxic smoke when burned. The flame-resistant qualities of neoprene make it a preferred choice in environments where smoke and fire hazards are a consideration, such as in the upholstery of public seating areas, thereby ensuring a higher level of safety for users.
