what material is PVDF?

PVDF is a kind of high performance polymer material, its full name is polyvinylidene fluoride. It has strong weather resistance, chemical resistance and heat resistance, but also shows excellent wear resistance and corrosion resistance. Therefore, it is widely used in construction, chemical, electronics and aviation and other fields.

the nature of PVDF

1. chemical resistance: PVDF in acid, alkali, oil and organic solvents and other aspects of excellent chemical resistance, with high corrosion resistance.

2. Heat resistance: PVDF has high temperature resistance, can withstand high temperatures of 120°C, and can maintain toughness at low temperatures of -40°C.

3. UV resistance: PVDF has good UV resistance and can be used in outdoor environments.

4. Wear resistance: Because PVDF has high hardness and low wear resistance, it is often used to manufacture mechanical equipment with high friction performance requirements such as conveyor belts.

5. Good electrical insulation: PVDF shows very good performance in electrical insulation and has low dielectric loss.

PVDF application

1. construction: PVDF is widely used in the manufacture of building curtain wall, can effectively resist the erosion caused by ultraviolet rays, acid rain and other natural environment, but also has the advantages of fire prevention, wear resistance and so on.

2. Chemical industry: PVDF can be used in the manufacture of chemical storage tanks, pipelines and valves. It has high corrosion resistance and chemical resistance, and can effectively prevent the harm of chemicals to the environment and human body.

3. Electronics industry: PVDF can be used to manufacture electronic components such as diaphragms and circuit boards, with good electrical insulation properties.

4. Aviation field: PVDF can be used to manufacture aircraft external covering materials, which has high chemical resistance and corrosion resistance, and can reduce the evaporation and loss of aircraft fuel.

advantages of PVDF:

1. corrosion resistance: PVDF has a good acid and alkali resistance, can resist the erosion of many strong corrosive substances.

2. High temperature resistance: PVDF has very good high temperature resistance, can withstand a high temperature environment of 120°C, and can maintain toughness at a low temperature of -40°C.

3. wear resistance: PVDF surface hardness, good wear resistance, very suitable for processing and manufacturing molding.

4. UV resistance: PVDF has good UV resistance and can resist the erosion of outdoor environment for a long time.

conclusion:

comprehensive above, PVDF as an excellent material, in various fields have a wide range of applications. Its excellent performance can effectively improve production efficiency and product quality, and contribute to the development of the industry.
