Are You Working on a CNC Project that Requires the Exceptional Performance of PVDF Materials?
The demand for CNC machining services of fluoropolymers such as Kynar® PVDF is growing across various industries worldwide, driven primarily by the increasing popularity of specialized, small-batch production of custom parts and components. For companies developing prototype products, partnering with a fluoropolymer parts manufacturer like Elimold is incredibly convenient. Elimold’s extensive experience in custom engineering plastics ensures that we consistently meet our customers’ evolving needs with the same innovative spirit and dedication, and are committed to creating new value in fluoropolymer applications.
What is PVDF?
Polyvinylidene fluoride (PVDF) is a semi-crystalline fluoropolymer, commercially known as Kynar®, whose basic unit is the repeating vinylidene fluoride (VDF) monomer, with the chemical formula (C₂H₂F₂)n. The free-radical polymerization of VDF produces molecular chains composed of alternating -CH₂- and -CF₂- groups. This polymer structure gives PVDF its unique polarity, making it extremely useful in applications requiring excellent thermal stability and electrical properties.
It is a high-purity thermoplastic made from high molecular weight fluorocarbons. It possesses efficient piezoelectric and pyroelectric properties. These characteristics make it widely used in sensor and battery applications. PVDF has a glass transition temperature (Tg) of approximately -350 degrees Celsius, and its crystallinity is typically 50-60%. It is one of the toughest fluoroplastics, with the lowest coefficient of friction, and excellent corrosion resistance, aging resistance, weather resistance, and radiation resistance. In addition, PVDF exhibits high mechanical strength and toughness.
Properties of Polyvinylidene Fluoride
The widespread use of polyvinylidene fluoride (PVDF) is due to its excellent physical and chemical properties. Among the most important properties are:
- Inertness to food contact
- Excellent compression, creep, and impact resistance, and high rigidity
- Unaffected by strong acids and bases
- Hydrolysis resistance and high water resistance
- Excellent sliding properties
- Ability to withstand weathering and UV radiation
- Easy to maintain desired dimensions
- High tolerance to temperature variations (up to +150°C)
- Low flammability
- Ease of plastic and mechanical processing
CNC Machining Grades of PVDF Material
Polyvinylidene fluoride (PVDF) is available in two formulations: homopolymer and copolymer.
- Homopolymer PVDF plastic has higher strength, stiffness, and better thermal deformation properties than copolymer PVDF plastic.
- Copolymer PVDF plastic has lower stiffness than homopolymer PVDF plastic, but offers higher impact resistance and stress crack resistance.

FAQ
While polytetrafluoroethylene (PTFE) offers excellent chemical resistance, polyvinylidene fluoride (PVDF) surpasses it in terms of mechanical strength, stiffness, and dimensional stability. PVDF is also easier to process and weld, making it more cost-effective in many applications. Its piezoelectric properties and flame retardancy set it apart among fluoropolymers.
Absolutely. PVDF exhibits exceptional UV resistance and weatherability, maintaining its performance even after decades of outdoor exposure. It is widely used in applications such as construction, outdoor chemical storage, and solar panel components. This material resists degradation from sunlight, rain, and temperature cycling.
PVDF can be effectively welded using techniques such as hot air welding, extrusion welding, or butt fusion welding. While bonding can be challenging due to PVDF's low surface energy, surface treatments can improve adhesion. We offer comprehensive PVDF welding and assembly services.
Yes, PVDF is widely used in semiconductor, pharmaceutical, and ultrapure water applications. The material exhibits extremely low levels of extractables and particulate generation. Natural PVDF contains no additives or stabilizers that could contaminate sensitive processes. We also offer special high-purity grades for the most demanding applications.
PVDF is an excellent choice for applications requiring a high-purity engineering thermoplastic with good chemical resistance, UV stability, flame retardancy, and abrasion resistance, and it offers good weldability using thermoplastic welding equipment.
