PVDF Tube – High Purity, Chemical Resistant Tubing from Shenzhen Forbest

When you’re moving aggressive chemicals or high-purity water, regular plastic tubing won’t last. PVDF (Polyvinylidene Fluoride) is a different class of material. It handles acids, bases, solvents, and high temperatures without breaking down.

Why PVDF instead of other plastics?
Most thermoplastics soften under heat or swell when exposed to chemicals. PVDF stays stable. It works continuously from -40°C up to 150°C. It resists strong sulfuric acid, sodium hydroxide, chlorine, and ozone. And unlike PTFE, PVDF holds its shape under pressure – no creeping or cold flow.

What you get from Forbest:

• Virgin resin only (no regrind, no filler)

• Tight tolerances (OD ±0.05mm on small diameters)

• Smooth inner surface for low flow resistance

• No surface contamination – packed dust-free

We supply PVDF Tube to semiconductor fabs, chemical plants, water treatment facilities, and electroplating shops. If your application demands purity and chemical resistance, this tubing is worth a close look.

How We Make It

Our production line runs in a dust-controlled 5,000m² workshop. Here’s the process:

1. Raw material – Virgin PVDF resin from Arkema or Solvay. Each batch has a traceable certificate.

2. Extrusion – Melt processing at controlled temperature. Real-time laser gauge monitors diameter.

3. Vacuum sizing – Ensures consistent ID and OD. No ovality issues.

4. Annealing – Relieves internal stress. Prevents cracking later.

5. Cutting or coiling – Straight sticks (1m, 2m, 3m) or long coils (up to 100m for small diameters).

6. Testing – Dimensional check, visual inspection, hydrostatic test for pressure-rated tubes.

Every shipment includes a Certificate of Analysis (CoA) with batch traceability.
