What Is PVDF Rod?

PVDF (Polyvinylidene Fluoride) Rod is a high-purity, non-reactive cylindrical product made from PVDF resin—one of the most versatile fluoropolymers available today. Unlike fully fluorinated polymers that can be difficult to process, PVDF is partially fluorinated, allowing for easy extrusion into thick cross-sections or large diameters without compromising structural integrity. This unique balance of processability and performance means PVDF Rod can be customized to fit specific project needs, from small precision components to large industrial parts.

What sets PVDF Rod apart is its ability to maintain consistency across diverse applications: it resists degradation from corrosive fluids, stands up to extreme temperatures, and meets strict regulatory standards (including FDA approval for food contact). Whether you’re building fluid handling systems, electronic insulators, or food processing equipment, PVDF Rod ensures long-lasting reliability and reduced maintenance costs.

Key Properties and Advantages

Exceptional Chemical Resistance

PVDF Rod demonstrates remarkable chemical inertness, resisting attack from strong acids, bases, and solvents. It withstands exposure to concentrated sulfuric acid (up to 98%), nitric acid, and other aggressive media, maintaining structural integrity where other materials would fail.

Thermal Performance 

With a continuous service temperature from -40°C to 150°C and a melting point of approximately 172°C, our PVDF rods perform reliably in both high-temperature and cryogenic applications. The material maintains excellent mechanical properties even at elevated temperatures, with tensile strength retention exceeding 85% after 1000 hours at 150°C.

Electrical Properties 

With a dielectric strength of 20kV/mm and volume resistivity of 1×10¹⁴ Ω·cm, PVDF Rod offers excellent electrical insulation properties, suitable for various electrical and electronic applications.
