PVDF Rod

I. Core Performance Advantages

PVDF rod delivers outstanding corrosion resistance, mechanical strength, high cleanliness and weather resistance. It is a premium anti-corrosion structural material to replace metals and ordinary engineering plastics. Key properties are listed below:

1. Resistance to strong chemical corrosion
   It withstands most highly corrosive media including concentrated sulfuric acid, hydrofluoric acid, concentrated alkali, hydrogen peroxide and etching mixed solutions. It maintains stable performance within the temperature range of -40℃ ~ 120℃. No swelling, cracking or pulverization after long-term immersion, suitable for wet processing environments with strong acids and alkalis.
   
   

2. High rigidity & creep resistance
   High rigidity and hardness. Its flexural modulus and anti-creep performance are remarkably better than PTFE with no cold flow deformation. It resists bending and warping under thermal cycling and long-term pressure. The dimensional accuracy of precision machined parts remains stable over time.
   
   

3. High cleanliness & low leaching
   High-grade raw materials with extremely low metal ion leaching and no impurity contamination. The extruded rod has a compact internal structure with smooth, fine machined surfaces. It minimizes crystal adhesion and particle shedding, meeting strict cleanliness requirements for ultra-pure processes in semiconductor, photovoltaic and pharmaceutical industries.
   
   

4. Flame retardant & long service life
   Virgin PVDF achieves UL94 V-0 flame retardant rating without extra flame retardant additives. It is self-extinguishing and produces no dripping melt. It resists UV radiation, moisture, acid & alkali fume aging for long-term service under outdoor and high-temperature corrosive conditions.
   
   

5. Easy machining & weldability
   It can be precision machined via turning, milling, drilling and tapping. Hot melt welding enables joining, and the weld strength is close to that of base material, facilitating on-site construction and custom equipment fabrication.

II. Customizable Product Portfolio

We provide comprehensive customization based on client working conditions and equipment installation requirements, covering dimensional specifications and performance modification.
