Product Advantages
Excellent Chemical Corrosion Resistance: This is PVDF's most prominent advantage. It can withstand most strong acids, strong alkalis, strong oxidants, halogens, and organic solvents. Its chemical resistance is far superior to general-purpose plastics such as PP and PE, and even superior to many metals. Suitable for extremely harsh chemical environments.
Excellent High Temperature Resistance: Long-term operating temperature can reach -40°C to +150°C, and short-term operation can withstand even higher temperatures. This makes it suitable for high-temperature fluid pipelines or high-temperature sterilization applications.
High Purity and Low Eluent: It has high purity, does not contaminate the media, and has extremely low leaching. It is an ideal choice for semiconductor, photovoltaic, pharmaceutical, and food-grade high-purity water systems.
Excellent mechanical strength and creep resistance: Excellent hardness, stiffness, and impact resistance; maintains shape stability under long-term pressure.
Superior aging and UV resistance: Minimal performance degradation after long-term outdoor use.
Flame retardancy: Intrinsically flame-retardant; self-extinguishing flames, meeting stringent fire safety requirements.
Excellent electrical insulation.
