Customized Good Chemical Stability PVDF Rod/Tube/Gasket/Sheet

Customized Good Chemical Stability PVDF Rod/Tube/Gasket/Sheet:
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.
Characteristic
1. High rigidity and high strength
2. Toughness, wear resistance, excellent creep resistance
3. Excellent chemical stability, good corrosion resistance
4.Anti-aging properties, anti-ultraviolet
5. Good mechanical performance, easy welding, thermoforming and other machining
6. Insulation resistance, high dielectric strength, low flammability
 Application
1. The best materials for petrochemical equipment, fluid handling systems as a whole or lined pumps, valves, piping, tanks and heat exchangers.
2. To meet the requirements of anti-corrosion and fire-retardant, widely used in the semiconductor industry on high-purity chemical storage and delivery devices.
3. Other pump parts, rotary disc, valve, stop valve, extraction centrifuge, cog wheel, pipe connections, slide, etc.
