Product Overview
Anti static PTFE sheet (also called conductive or ESD PTFE sheet) is made by compounding PTFE with conductive fillers such as carbon black, graphite, or carbon nanotubes, or via a permanent conductive surface treatment. It provides controlled surface resistivity (ESD-safe range) while retaining PTFE’s excellent chemical resistance, thermal stability, and low friction. Ideal for electronics manufacturing, cleanrooms, chemical handling, and hazardous environments where static control plus chemical inertness are required. Available in standard sheets, custom thicknesses, and die-cut parts.
-
Prevents static discharge damage in electronics manufacturing and reduces dust attraction in clean environments.
-
Enables use of PTFE where static control is required (previously a barrier due to PTFE’s insulating nature).
-
Customizable conductivity levels and thicknesses for specific process or regulatory needs.
-
Backed by technical datasheets, COA and test reports to support procurement approval.
Key Features & Quick Facts
-
ESD / anti-static performance — conductive fillers or surface treatments provide controlled surface resistivity (per spec).
-
Chemical inertness — same broad chemical compatibility as PTFE (pH 0–14).
-
Low friction & non-stick — reduces wear and particle generation.
-
Wide temperature range — typically −200°C – 260°C depending on grade.
-
Available formats — standard sheet sizes, rolls, die-cut gaskets and liners.
-
Cleanroom & FDA options — low-outgassing and FDA-compliant grades available on request.

Material Comparison — Anti Static PTFE vs Alternatives
| Feature / Material | Anti-Static PTFE | Standard PTFE | ESD Rubber / Conductive Elastomer | Carbon-Filled UHMW / PE |
|---|---|---|---|---|
| Chemical resistance | Excellent | Excellent | Moderate | Moderate–Good |
| Surface resistivity | 10^3–10^9 Ω/sq (tunable) | Insulative (>10^12 Ω/sq) | 10^3–10^9 Ω/sq | 10^3–10^8 Ω/sq |
| Friction / wear | Very low | Very low | Higher | Low–Moderate |
| Temperature range | −200 to +260°C | −200 to +260°C | −40 to +150°C | −100 to +120°C |
| Cleanroom compatibility | High (low outgassing) | High | Variable | Variable |
| Best use case | ESD + chemical environments | Chemical/purity needs without ESD | Low temp ESD mats, gaskets | Heavy wear + ESD needs |
Positioning note: anti static PTFE is the go-to when both ESD control and chemical/thermal performance are required — alternatives trade off one for the other.

FAQ
Q1: What is the minimum order quantity (MOQ)?
A: Typical MOQ for stock sheets is 5–10 sheets per SKU. Custom die-cut orders generally start at 50–200 pcs per design. Contact sales for small-batch or trial orders.
Q2: What are typical lead times?
A: Stock sheets ship in 1–5 business days. Custom conductivity grades or die-cut parts: 7–21 calendar days depending on quantity and tooling.
Q3: Can you achieve specific surface resistivity targets (e.g., 10^6 Ω/sq)?
A: Yes — specify required surface resistivity or ESD class in your RFQ. We’ll propose the filler system and confirm test reports with your quote.
Q4: Do you ship internationally and what documents are provided?
A: Yes. We ship worldwide via express, air and sea and provide COA, resistivity test report, packing list and commercial invoice. Incoterms negotiable.
Q5: Are there FDA or cleanroom compatible grades?
A: Yes — low-outgassing and FDA-compatible formulations are available for regulated industries. Specify certification needs at RFQ.
Q6: Can you die-cut or laminate these sheets?
A: Yes — we offer die-cutting, CNC/waterjet cutting, laminations and adhesive-backing options. Provide DXF/CAD drawing or sample for quoting.
Q7: How should I test conductivity after installation?
A: Use a calibrated surface resistivity meter per ASTM D257 or IEC 61340 standards. For best practice, test at multiple points and document results.
Q8: What warranty and returns policy do you offer?
A: We warrant material per stated datasheet and for manufacturing defects. Returns for custom compounded grades are limited; consult our sales team for full T&C.
