Fluorine-lined Valve Manufacturers Briefly Analyze The Introduction Of Fluorine-lined Valve Lining Materials

What are the lining materials of Lined Valve? You can take a look at the following introduction:

Polytetrafluoroethylene PTFE (F4)

Medium: strong acid, strong alkali, strong oxidant, etc.: Operating temperature: -200~180℃

Features: excellent chemical stability, high heat resistance, good cold resistance: low friction coefficient, it is an excellent self-lubricating material, but it has low mechanical properties, poor fluidity, and large thermal expansion. Polytetrafluoroethylene propylene FEP (F46)

FEP (F46) operating temperature: -85～150℃

Features: mechanical, electrical properties and chemical stability are basically the same as F4, but the outstanding advantages are high dynamic toughness, good weather resistance and radiation.

Ethylene PCTEF (F3) aggregation operating temperature: -195～120℃

Features: heat-resistant hydrocarbons, electrical properties and chemical stability are second only to F4 in mechanical strength, glutinous dynamics and hardness.

Polyvinylidene fluoride PVDF (F2)

Applicable media: Resistant to most chemicals and solvents: Operating temperature: -70~100℃

Features: Tensile strength and compression strength are better than F4, with advantages such as bending, weather resistance, radiation, light resistance, and aging. The biggest feature is good toughness and easy molding.

Polypropylene RPP

Using temperature: -14~80℃:

Features: One of the lightest plastics, its yield, tensile, compression strength and hardness are better than low-pressure polyethylene, with outstanding rigidity, good heat resistance, easy molding, high quality and low price. After improvement, the dynamic impact, fluidity and bending elastic modulus are improved.

Polyolefin PO

Using temperature: -58~80℃:

Features: It is an ideal anti-corrosion material in the world and has been widely used in rotational molding of large equipment and pipe fittings.

PCVPCV using temperature: 0-～55℃:

Features: high mechanical strength, excellent chemical stability and dielectric properties, good oil resistance and anti-aging properties, easy to weld and bond, and low price. The shell and connection dimensions of various lined pipeline valves are the same as the nominal ones, but the lining materials can be used according to different media. Modified polyolefin PO, polypropylene RPP, polyperfluoroethylene propylene F46, polytetrafluoroethylene F3, polytrifluoroethylene F3, polyvinylidene fluoride F2.
