PVDF sleeve couplings are primarily made from Polyvinylidene Fluoride material, which grants them a series of prominent features:
Excellent Chemical Corrosion Resistance: Withstands most strong acids, alkalis, and organic solvents, making them suitable for highly corrosive chemical environments.
Superior High-Temperature Resistance: Wide operating temperature range; some products can operate stably long-term in environments from -40°C to 200°C. This also makes them suitable for applications with high temperatures or prolonged UV exposure.
High Purity and Mechanical Strength: PVDF material itself is of high purity, preventing media contamination, making it ideal for semiconductor ultrapure water, food and beverage, and biopharmaceutical applications. It also possesses good mechanical strength, creep resistance, and fatigue resistance.
Certifications and Safety: Sealing elements in some PVDF couplings comply with FDA standards, and some products overall meet FDA material standards. They may also have KTW, NSF, and other certifications, meeting the hygiene and safety requirements of specific industries.
