PVDF Rods & Sheets: Strength, Chemical Resistance, and UV Stability

Index

Introduction

PVDF (Polyvinylidene Fluoride) is a versatile, high-performance melt-processable fluoropolymer valued for its excellent balance of chemical resistance, high mechanical strength, UV stability, and inherent flame retardancy. Unlike PTFE, PVDF offers greater stiffness and abrasion resistance, making it suitable for demanding structural and fluid-handling applications where durability is key. As an integrated PVDF resin manufacturer and supplier of semi-finished products, Xiflon delivers high-quality PVDF rods and PVDF sheets for various industrial sectors.

Key Properties & Advantages of PVDF

  • Excellent Chemical Resistance: Resists a broad range of aggressive chemicals, including acids, bases, halogenated solvents, and hydrocarbons. Particularly known for resistance to halogens like chlorine and bromine.
  • High Mechanical Strength & Stiffness: Offers superior tensile strength, impact resistance, and rigidity compared to PTFE, FEP, or PFA.
  • Outstanding UV & Weather Resistance: Highly resistant to degradation from sunlight exposure, making it ideal for outdoor applications like architectural coatings and components.
  • Good Abrasion Resistance: Provides better wear resistance than many other fluoropolymers.
  • Inherent Flame Retardancy: Typically meets UL 94 V-0 ratings without additives.
  • Good Thermal Stability: Suitable for continuous use up to approximately +150°C.
  • Piezoelectric Properties: Certain grades exhibit piezoelectric and pyroelectric effects, useful in sensor applications (though less relevant for standard rods/sheets).
  • Ease of Processing: Readily melt-processable via extrusion and injection molding; machinable and weldable.

Xiflon’s PVDF Product Offering

Leveraging our in-house PVDF resin production, we supply:
