What are the effects of prolonged exposure to bleach on polypropylene?
Prolonged exposure to bleach can significantly impact polypropylene, a widely used plastic known for its chemical resistance. While polypropylene is generally resistant to many chemicals, continuous contact with bleach may lead to surface degradation, discoloration, and reduced structural integrity over time. Bleach, especially in concentrated forms, can break down polymer chains, causing brittleness and cracks. The extent of damage depends on factors like bleach concentration, exposure duration, and environmental conditions. To maintain polypropylene's durability, it's advisable to limit direct bleach exposure and rinse thoroughly after cleaning. Understanding these effects helps in selecting appropriate materials for applications involving harsh chemicals.
