What is Polyvinylidene-fluoride (PVDF)?

Polyvinylidene fluoride (PVDF) is a high-performance, fluoropolymer-based plastic that is known for its excellent chemical resistance, high strength, and low friction properties. It is commonly used in a variety of applications where these properties are beneficial, including in the production of screws, nuts, bolts, and washers.

PVDF - Key Properties

Polyvinylidene fluoride (PVDF) is a type of polymer that is made from monomers called vinylidene fluorides. It is a semi-crystalline fluoropolymer that has excellent mechanical and thermal properties, making it suitable for use in a wide range of applications.

Some of the main properties of PVDF include:

High strength: PVDF has a high tensile strength and a high modulus of elasticity, making it a popular choice for use in structural applications where high strength and stiffness are required.

High temperature resistance: PVDF can withstand temperatures up to 150°C (302°F) continuously and up to 200°C (392°F) for short periods of time, making it suitable for use in high temperature applications.

Chemical resistance: PVDF has excellent chemical resistance and is resistant to a wide range of chemicals, including acids, bases, and organic solvents. It is also resistant to UV radiation and weathering, making it a good choice for outdoor applications.

Electrical insulation: PVDF has good electrical insulation properties and is often used in electrical and electronic applications where high temperature resistance and good electrical insulation are required.

Low coefficient of friction: PVDF has a low coefficient of friction, making it an excellent choice for use in applications where low friction is required.

PVDF is a high performance polymer that is known for its excellent mechanical and thermal properties, as well as its excellent chemical resistance and low coefficient of friction. It is a versatile material that is used in a wide range of applications where its unique properties make it a suitable choice.
