Fluorine Lined Ball Valve Lining Material

Lined Ball Valve Main lining material - Fluoroplastic:
Perfluoroethylene FEP (F46)
Applicable media:
Any organic solvent or reagent, dilute or concentrated inorganic acid, alkali, ketone, aromatic hydrocarbon, chlorinated hydrocarbon, etc.
Using temperature:
-85~150
Features: Mechanical, electrical properties and chemical stability are basically the same as F4, but the outstanding advantage is high dynamic toughness, excellent weather resistance and radiation.
Polypropylene: RPP
Applicable media: Aqueous solutions of inorganic salts, dilute or concentrated solutions of inorganic acids and alkalis.
Using temperature: -14~80
Features: One of the lightest plastics, its yield, tensile and compressive strength, hardness are better than low-pressure polyethylene, with outstanding rigidity, good heat resistance, easy molding, and low cost. After modification, dynamic impact, fluidity, and bending elasticity.
Polyvinyl chloride: Rigid) PVC
Applicable media: Water resistance, concentrated alkali, non-oxidizing acid, chain hydrocarbon, oil and ozone, etc.
Use temperature: 0-55
Features: high mechanical strength, excellent chemical stability and dielectric properties, good oil resistance and aging resistance, easy to weld and bond, low price.
Polytetrafluoroethylene PTFE (F4)
Use medium: strong acid, strong alkali, strong oxidant, etc.
Use temperature: -200~180
Features: It has excellent chemical stability, high heat resistance, cold resistance, low friction coefficient, and is an excellent self-lubricating material, but has low mechanical properties, poor fluidity, and large thermal expansion.
Polyolefin: PO
Applicable medium: various concentrations of acid, alkali, salt and some organic solvents.
Use temperature: -58~80
Features: It is the world's most ideal anti-corrosion material and has been widely used in large-scale rotational molding equipment and pipeline linings.
Soluble polytetrafluoroethylene PFA
Use medium: Use medium: strong acid, strong alkali, strong oxidant, etc.
Operating temperature: -50-180
Features: Excellent chemical stability, high heat resistance, cold resistance, low friction coefficient, and an excellent self-lubricating material, but with low mechanical properties, poor fluidity, and large thermal expansion. The performance is better than F4, and the color is transparent and off-white.
