Polyvinylidene fluoride, or PVDF, is a cost-competitive and high-performing polymer. PVDF\u2019s inherent purity and extreme hardness make this material ideal for a variety of applications requiring exposure to extreme conditions. PVDF can be used over a wide temperature range and shows excellent abrasion resistance and very low permeability.<\/p>\n
PVDF is melt-processable, and its alternating CH2<\/sub>\u00a0and CF2<\/sub>\u00a0groups result in a polymer with high chemical resistance; it is inert to most aromatic and aliphatic hydrocarbons, acids, chlorinated solvents, and alcohols. PVDF\u2019s chemical resistance likewise carries over to its combustion: PVDF is highly flame-resistant and is categorized as a self-extinguishing material. PVDF\u2019s UL 94 V-0 rating means that even if the material ignites, it will burn no more than 10 seconds with no flaming or drips.<\/p>\n PVDF is resistant to UV and gamma radiation, enabling it to tolerate extended exposure to sunlight. PVDF exhibits excellent resistance to creep, fatigue, and cut-through and maintains its dielectric strength of up to 1700 volts\/mil throughout its wide service temperature range. PVDF is melt-weldable and thermoformable.<\/p>\n PVDF tubing (also known as Kynar\u00ae<\/sup>) is used in many industries such as aerospace, oil and gas exploration, automotive, electronics, semiconductor, food and beverage, pharmaceutical, fiber optics, and medical. In addition to its good performance-to-cost ratio, PVDF\u2019s physical properties have made it a popular choice for applications requiring flexibility without sacrificing performance.<\/p>\n
