Ⅰ. PVDF Description
PVDF owns excellent chemical resistance, aging resistance, processing performance, dimensional stability, fatigue
resistance and creep resistance. Compared with PTFE, PVDF shows a higher rigidity and pressure resistance when
compared with PTFE, and high toughness at low temperature, but the smoothness and electrical insulation properties is lower. PVDF continuous using temperature range -30-150 ° C .
II. PVDF Characteristics
♦ High rigidity and high strength
♦ Toughness, wear resistance, excellent creep resistance
♦ Excellent chemical stability, good corrosion resistance
♦ Anti-aging properties, anti-ultraviolet
♦ Good mechanical performance, easy welding, thermoforming and other machining
♦ Insulation resistance, high dielectric strength, low flammability
♦ Toughness, wear resistance, excellent creep resistance
♦ Excellent chemical stability, good corrosion resistance
♦ Anti-aging properties, anti-ultraviolet
♦ Good mechanical performance, easy welding, thermoforming and other machining
♦ Insulation resistance, high dielectric strength, low flammability
Ⅲ. PVDF Applications
♦ The best materials for petrochemical equipment, fluid handling systems as a whole or lined pumps, valves, piping, tanks and heat exchangers.
♦ To meet the requirements of anti-corrosion and fire-retardant, widely used in the semiconductor industry on high-purity chemical storage and delivery devices.
♦ Other pump parts, rotary disc, valve, stop valve, extraction centrifuge, cog wheel, pipe connections, slide, etc.
