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.
