About anti-corrosion lining material
PTFE(F4)
The applicable media: strong acid, strong alkali, strong oxidizer, etc. applicable temperature: - 200 ~ 180 ℃
Characteristic: with excellent chemical stability, high heat resistance, cold resistance: low friction coefficient, is an excellent self-lubricating material, but mechanical properties is lower, poor mobility, large thermal expansion.
FEP(F46)
Applicable medium: any organic solvents or reagents, diluted or concentrated inorganic acids, alkalis, ketones, aromatics, chlorinated, etc.:applicable temperature：-85～150℃
Features: mechanical, electrical properties and chemical stability are basiclly same with F4, but highlight advantages are high moving toughness, with excellent weatherability and radioactive.
PCTEF(F3)
Applicable medium: all kinds of organic solvents, inorganic corrosion solution (oxidizing acids): applicable temperature：-195～120℃ Features: heat-resistant hydrocarbon, electrical properties and chemical stability are only inferior to F4; mechanical strength, waxy dynamic performance, hardness are better than F4.
PVDF(F2)
Applicable medium: resistance to most chemicals and solvents:
applicable temperature：-70~100℃
Characteristics: tensile strength and compressive strength are better than F4, bending resistance,
weathering resistance, radiation resistance, light and aging resistance, the largest feature is a good
tenacity, easy to shape
RPP
Applicable medium: aqueous solution of inorganic salts, inorganic acids, the quenched with alkali solution:
applicable temperature：-14～80℃：
Features: One of the lightest plastic, its yield, tensile and compressive strength and hardness are superior to low-pressure polyethylene, with a very prominent rigidity, heat resistance is good, easy molding, excellent inexpensive and after changing, the strike movement, mobility, bending elastic modulus increases.
PO
The applicable media: Various concentrations acid and alkali salts and some organic solvents:
applicable temperature：-58～80℃：
Features: It is currently the world's best anti-corrosion materials, has been widely used in rotating molding pieces large equipment and pipe lining.
PCV
Applicable medium: waterproof, concentrated alkali, non-oxidizing acid, chain hydrocarbon, oil and ozone, etc.
applicable temperature：0-～55℃：
Characteristics: high mechanical strength, chemical stability and good dielectric properties, oil resistance and anti-aging nature is also better and easy to weld and bond, price is lower. Various types of lining pipes valves and nominal diameter and linking dimensions are the same, but the lining material according to different media, can be used following different lining materials. Modified PO, RPP, FEP F46, PTFE F3, PCTEF F3, PVDF F2.
