Manufacturing Methods – Molded vs. Extruded PTFE Rods
Molded PTFE Rods
- ✅ Compression‑molded in a press
- ✅ Larger diameters (up to 400 mm)
- ✅ Excellent dimensional stability
- ✅ Ideal for short‑run, custom sizes
- ✅ Suited for filled grades
Extruded PTFE Rods
- ✅ Continuous ram or paste extrusion
- ✅ Smaller diameters (5–100 mm)
- ✅ Longer lengths, consistent quality
- ✅ Cost‑efficient for high‑volume orders
- ✅ Excellent surface finish
Both options are available at Kaxite – consult us to choose the best manufacturing method for your application.

Frequently Asked Questions – PTFE Rods
What is the difference between molded and extruded PTFE rods?
Molded rods are compression‑molded in a press, allowing larger diameters (up to 400 mm) and custom shapes. Extruded rods are produced by continuous extrusion, offering longer lengths and consistent quality for smaller diameters (5–100 mm).
What is the maximum diameter available for PTFE rods?
We can supply molded PTFE rods up to 400 mm in diameter. For larger diameters, please consult our engineering team for feasibility.
What filled grades are available for PTFE rods?
We offer glass‑filled, carbon‑filled, graphite‑filled, bronze‑filled, and custom compounds to enhance wear resistance, thermal conductivity, or electrical properties.
Can Kaxite provide custom‑cut lengths?
Yes, we offer custom cutting to length and can supply rods in specific dimensions to reduce your machining waste and preparation time.
Are PTFE rods FDA‑compliant?
Yes, our virgin PTFE rods comply with FDA 21 CFR 177.1550 and are suitable for food, beverage, and pharmaceutical contact applications. Filled grades may require additional validation.
