PVDF Material Introduction:
Saferlon® PVDF sheet is manufactured by extruding with PVDF resin under high temperature. It’s a relative pure polymer without additives such as UV stabilizer, heat stabilizer, softener, lubricant, and fire retardant etc..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 -60-150 °C.
PVDF has a good chemical stability. It will not be corrupted by acid, alkali, strong oxidizing agent and halogen at room temperature; it will not be affect by ordinary organic solvents; it can only be swelling or partly dissolved by a handful of chemicals such as fuming sulfuric acid, alkali, ketones and ether; it can be dissolved into a colloidal solution by strong polar organic solvents such as dimethyl acetamide and Dimethyl Sulfoxide(DMSO). Moreover, its water absorption is only 0.03% in 80℃; Its chlorine penetrability is the smallest among fluorine resins
Applications of PVDF:
♦ 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.
♦ Be used in the fields of electronics industry about LED related devices, chemistry equipment and food processing machinery.
♦ Also for metal reactor, metal anti-corrosion chemical containers lining
♦In environmental protection field, can be used for the lining of glassed steel reactor, plastic liner of enamel reactor and anti-corrosion lining of pipeline .
♦ Other pump parts, rotary disc, valve, stop valve, extraction centrifuge, cog wheel, pipe connections, slide, etc.
