Product Description

PTFE RODS

There are 3 different types of Forming process for PTFE Rod.
Diameter: 1mm-4mm, produced via Paste extrusion forming from dispersion resins. Normally in Roll package.
Diameter: 3mm-160mm, produced via plunger Pushing method from PTFE Suspension resins.
Diameter: between 6mm to 400mm can be produce into short rod by molding method, the Short molded rod can be mixed with inorganic materials such as fiberglass, bronze, graphite, carbon, or molybdenum sulfide (compounds). This can significantly alter the properties, particularly with regard to pressure resistance, thermal expansion, electrical values, and abrasion.
Of all the known plastics , PTFE has the most excellent chemical resistance and dielectric properties , anti-aging, non-stick , can be worked under a temperature of -180 ºC ~ + 260 ºC(zero load working environment) , it has the lowest coefficient of friction among all known solid material.

Project name	Unit	index
Apparent Density	g/cm3	2.10~2.30
Tensile strength ≥	MPa	14.0
Ultimate elongation ≥	%	140

Forming process for PTFE Molded Rod:
Step 1: PTFE Resin mixed with additives.
Step 2: Compression: Put the compounded PTFE material into Molds, compression into billets with certain temperature and time.
Step 3: Sintering: Then Heat the PTFE billets to melting point in the Oven, the PTFE Resin molecule are are closely packed by sintering.
Step 4: It can be machined or directly use after cooling.
Molding method Feature: Low output, the dimensional changes Seriouly during sintering, only suitable for big size and simply designed products.

PTFE  Rods applications :
PTFE Molded Rods are mainly used for machining into various of circular parts such as ,gaskets, washers, shafts ,special-shaped pieces and so on .

FAQ

1.Q: How to distinguish pure PTFE from filled PTFE sheets?
   A: Pure PTFE is white without additives (labeled "Virgin PTFE"); filled types specify additives and may appear gray/off-white.
 
2. Q: Are the products certified with international standards ?
   A: Pure PTFE complies with FDA . Filled types depend on formulations.  

3. Q:  Can I request samples?
   A: Free 20×20cm samples are provided (shipping cost paid by buyer).  

4. Q: What is the lead time for custom sizes/thickness?  
   A: Standard sizes ship in 7 days; custom orders take 15-30 days (based on complexity).  

5. Q: How to verify chemical resistance data?
   A: Third-party test reports.  

6. Q: What is the packaging ?  
   A: With wooden crates, suitable for sea/air freight.  

7. Q: Will harmful substances be released ?  
   A: Pure PTFE is stable up to 250ºC; filled types require additive verification.  

8. Q: Can you deburr sheet edges or provide precision machining?  
   A: Standard sheets are rough-cut; CNC finishing (±0.1mm tolerance) is available at additional cost.  

9. Q: What if the product fails performance tests after delivery?  
    A: Disputes within 15 days require third-party test reports. Confirmed issues trigger free replacement or refund.
