PVC/FRP, PP/FRP, PVDF/FRP composite tanks

PVC/FRP, PP/FRP, and PVDF/FRP composite tanks are all types of storage tanks that are commonly used in various industries for storing chemicals, acids, and other liquids. While they are all made of a composite material consisting of fiber reinforced plastic (FRP) and a thermoplastic liner, there are some differences between them.

Material properties:

PVC/FRP: PVC (Polyvinyl Chloride) is a thermoplastic material that is known for its chemical resistance, good mechanical properties, and low cost. However, it has lower temperature and UV resistance compared to other thermoplastics.

PP/FRP: PP (Polypropylene) is a thermoplastic material that has excellent chemical resistance, good mechanical properties, and high temperature resistance. It is more expensive than PVC but offers better resistance to certain chemicals and higher temperature ranges.

PVDF/FRP: PVDF (Polyvinylidene fluoride) is a high-performance thermoplastic that offers excellent chemical and temperature resistance and is more expensive than PVC and PP.

Chemical resistance:

PVC/FRP: PVC offers good chemical resistance against most acids and alkalis but may not be suitable for some organic solvents and aromatic hydrocarbons.

PP/FRP: PP offers excellent chemical resistance against most acids, alkalis, and organic solvents, but it may not be suitable for some chlorinated solvents.

PVDF/FRP: PVDF offers excellent chemical resistance against most acids, alkalis, and organic solvents, including chlorinated solvents.

Temperature resistance:

PVC/FRP: PVC has a lower temperature range compared to PP and PVDF and may not be suitable for applications that require high-temperature resistance.

PP/FRP: PP has a higher temperature range compared to PVC and can handle temperatures up to 100°C.

PVDF/FRP: PVDF has the highest temperature range among the three and can handle temperatures up to 150°C.

Cost:

PVC/FRP: PVC is the least expensive among the three and is a good option for applications that do not require high-temperature or chemical resistance.

PP/FRP: PP is more expensive than PVC but offers better chemical resistance and can handle higher temperatures.

PVDF/FRP: PVDF is the most expensive among the three but offers the best chemical and temperature resistance.

In summary, the choice of PVC/FRP, PP/FRP, or PVDF/FRP composite tanks will depend on the specific application requirements such as the type of liquid to be stored, temperature, and chemical resistance needed, as well as budget constraints.
