What are the differences in flammability between polypropylene and PVC tables?
When comparing the flammability of polypropylene and PVC tables, several key differences emerge. Polypropylene is a thermoplastic polymer that melts when exposed to high temperatures, making it less flammable but prone to dripping, which can spread fire. PVC (polyvinyl chloride), on the other hand, contains chlorine, which gives it inherent flame-retardant properties. PVC tends to self-extinguish when the flame source is removed, reducing fire spread risk. However, burning PVC releases toxic gases like hydrogen chloride, posing health hazards. Both materials are widely used in furniture, but PVC generally offers better fire resistance, while polypropylene is more lightweight and flexible. Always check safety certifications for specific applications.
