PVDF (Poly Vinyle Dene Fluoride)

PVDF, Polyvinyledene Fluoride, is a highly nonreactive and pure thermoplastic fluoropolymer. It is also called HYLAR.

PVDF is a special plastic material from the fluoropolymer family. PVDF coating is a special-purpose coating that can be used in various applications that require the highest purity, strength, and resistance to solvents, acids, and bases, and for low smoke generation during a fire event.

PVDF coated components are used extensively in the high-purity semiconductor market (low extractable values), in the pulp and paper industry (chemically resistant to halogens and acids), nuclear waste processing (radiation and hot acid applications), chemical processing (chemical and temperature applications), and water treatment. This fluoropolymer can also meet specifications for the food and pharmaceutical processing industries. At elevated temperatures, PVDF can be dissolved in polar solvents such as organic esters and amines, making them practical for use in corrosion-resistant coatings and durable architectural finishes on building panels. PVDF coatings are easy to melt when compared with other fluoropolymers because of their low melting point of around 177°C. PVDF can be injected, molded, or welded.

Applications of HALAR Coatings

• HALAR coatings are used to minimize wear in high-frictional applications, where dimensional stability is a requirement.
• Typical applications include bearings, cams, valve seals, semiconductor tooling, and cables.
• This coating can be used as a bearing surface for machine tools.
• Can be used in electrical insulators due to high resistivity and low dielectric constant.
• Can be bonded by using the same type of epoxy resin or ultrasonics as other fluoropolymers.
• Chemical properties of HALAR coating resemble ETFE but with lower melting points.

HALAR Coatings are ideal for Chemical applications

HALAR is one of the most chemically resistant polymers that are available today. Some luminous characteristics of HALAR that meet the industrial demanding applications

• Excellent release properties
• Extremely smooth surface
• Dimensionally stable
• Low cold flow
• Ideal to operate at the temperatures (up to 300°F)
• Mechanically tough with excellent abrasion and impact resistance.
