What is the difference between PVC and PVDF?
What is the difference between PVC and PVDF?
PVDF operates at higher temperatures and is suggested up to 284 °F; CPVC up to 200 °F and PVC only to 140 °F. PVDF has increased mechanical durability over both PVC and CPVC. PVDF is more resistant to permeation and to a greater number of chemicals.
What is the difference between PVDF and polypropylene?
PVDF and PP sutures have very similar melting temperatures (165–175 °C), but distinctively different level of crystallinity. PVDF has a level of crystallinity 59% ± 7%, while PP has 43% ± 3%.
What is PVDF plastic used for?
PVDF (polyvinylidene fluoride), often referred to by its trade name Kynar®, is a high purity engineering thermoplastic with excellent chemical resistance, abrasion resistance, flame resistance, and UV stability. PVDF is widely used for chemical tank liners and semiconductor equipment components.
Is PVDF the same as PTFE?
PVDF and PTFE are short terms for polyvinylidene fluoride and polytetrafluoroethylene, respectively. The key difference between PVDF and PTFE is that PVDF has comparatively a low density, whereas PTFE has comparatively a high density.
Is PVDF a fluorocarbon?
However, as long as Arkema continues to protect its right to the trade name “Kynar 500,” the generic way to describe it is “polyvinylidene fluoride” or “PVDF.” This is not exactly the same thing as “Fluorocarbon resin.” PVDF is one of several Fluorocarbon resins. Another trade name used for PVDF is Hylar 5000.
What is PVDF pipe?
Polyvinylidene fluoride (PVDF; Kynar) is a superior thermoplastic and plumbing option among both plastic and metal pipe materials. PVDF plumbing has a maximum service temperature of 284 °F (150 °C) and max pressure design stress of 1,360 PSI at 73 °F with solid pipe rated up to 580 PSI.
What are the advantages of PVDF?
Advantages. Polyvinylidenedifluoride (PVDF) is the highest tensile strength of all processable fluorocarbons. It has good radiation resistance (better than other fluorocarbons), is melt processable and has a good abrasion resistance. Good general chemical resistance, although inferior to PTFE.
Is PVDF a piezoelectric?
PVDF has a glass transition temperature (Tg) of about −35 °C and is typically 50–60% crystalline. To give the material its piezoelectric properties, it is mechanically stretched to orient the molecular chains and then poled under tension. Thin films of PVDF are used in some newer thermal camera sensors.
Is PVDF an insulator?
PVDF is commonly used as insulation on electrical wires, because of its combination of flexibility, low weight, low thermal conductivity, high chemical corrosion resistance, and heat resistance.
Is polypropylene a Teflon?

What is polyvinylidene fluoride (PVDF)?
PVDF (polyvinylidene fluoride), often referred to by its trade name Kynar®, is a high purity engineering thermoplastic with excellent chemical resistance, abrasion resistance, flame resistance, and UV stability. PVDF is widely used for chemical tank liners and semiconductor equipment components. FDA compliant grades of PVDF are available.
What is the ASTM grade for PVDF?
(Polyvinylidene Fluoride) PVDF homopolymer conforming to ASTM D 3222, Type I, Grade 2, is a tough, abrasion-resistant fluorocarbon material that has a design stress of 1,360 psi at 73° F and a maximum service temperature of 280° F.
How do I view and compare plastic materials and material properties?
View plastic materials found under a specific property group: Click on the tab of a specific property group. Sort plastic materials: Click the down or up arrows (triangles) or column headings to sort plastic materials or material properties. Compare plastic materials: Select two or more materials and then press “Compare Materials”.
What is the difference between PVDF and PTFE?
The key difference between PVDF and PTFE is that PVDF has comparatively a low density, whereas PTFE has comparatively a high density. Moreover, PVDF is produced via polymerization of vinylidene difluoride, while PVDF is produced via free-radical polymerization.
