1. Polyperfluoroethylene FEP (F46): Suitable for any organic solvent or reagent, dilute or concentrated inorganic acid, alkali, ketone, aromatic hydrocarbon, chlorinated hydrocarbon, etc. Operating temperature: -85~150. Features: Mechanics, electrical properties and chemical stability are basically the same as F4, but the outstanding advantages are high dynamic toughness, excellent weather resistance and radiation.
2. Polytrifluoroethylene PCTEF (F3): Suitable for various organic solvents, inorganic etching solutions (oxidizing acids). Operating temperature: -195~120. Features: heat resistance, electrical properties and chemical stability are second only to F4, mechanical strength, creep properties, hardness is better than F4.
3. Polypropylene RPP: suitable for aqueous solutions of inorganic salts, rare or concentrated solutions of inorganic acids and alkalis. Operating temperature: -14~80. Features: One of the lightest plastics, its yield, tensile and compressive strength, hardness is better than low-pressure polyethylene, has outstanding rigidity, good heat resistance, easy to form, excellent and inexpensive. After modification, it is turbulent, fluid, and flexible.
4. Polyvinyl chloride: Hard) PVC: Suitable for water resistance, concentrated alkali, non-oxidizing acid, chain hydrocarbon, oil and ozone. Operating temperature: 0-55. Features: high mechanical strength, chemical stability and dielectric properties, oil resistance and anti-aging are also good, easy to weld and bond, the price is lower.
5. Polytetrafluoroethylene PTFE (F4): medium used: strong acid, strong alkali, strong oxidant, etc. Operating temperature: -200~180. Features: Excellent chemical stability, high heat resistance, cold resistance, low friction coefficient, excellent self-lubricating material, but low mechanical properties, poor fluidity and large thermal expansion.
6. Polyvinylidene chloride PVDF (F2): medium used: resistant to most chemicals and solvents. Operating temperature: -70~100. Features: Tensile strength and compressive strength are better than F4, resistant to bending, weathering and radiation. Light resistance and aging, etc., the biggest feature is good toughness and easy to form.
7. Polyolefin PO: Suitable for various concentrations of acid and alkali salts and certain organic solvents. Operating temperature: -58~80. Features: It is the most ideal anti-corrosion material in the world. It has been widely used in large-scale rotating equipment and pipe lining.
