What is PCTFE Material(Polychlorotrifluoroethylene)?
PCTFE (Polychlorotrifluoroethylene), also known commercially as Kel-F®, is a specialty fluoropolymer that offers exceptional moisture barrier properties combined with excellent optical clarity. Among all transparent plastics, PCTFE exhibits the lowest water vapor transmission rate, making it the material of choice for critical moisture-sensitive applications.
Our PCTFE products are manufactured to meet the highest purity standards, suitable for pharmaceutical, aerospace, chemical processing, and optical applications. We offer both virgin-grade PCTFE materials and custom-compounded grades PCTFE materials to meet specific application requirements.
Key Characteristics of PCTFE Material
Ultimate Moisture Barrier
Water vapor transmission rate below 0.1 g/m²/24h - the lowest among all transparent plastics. Ideal for protecting moisture-sensitive pharmaceutical and electronic products.
Superior Chemical Resistance
Resistant to strong acids, alkalis, and most organic solvents. PCTFE maintains its properties in harsh chemical environments where other plastics would degrade.
High Optical Clarity
Light transmittance exceeding 90%, combined with low refractive index variation. Suitable for optical windows, lenses, and applications requiring visual inspection.
Excellent Mechanical Properties
High hardness, low creep, and excellent dimensional stability. PCTFE components maintain tight tolerances even under continuous load and temperature cycling.
Wide Temperature Range
Continuous service temperature from -200°C to +120°C. Maintains mechanical and barrier properties across extreme temperature variations.

Frequently Asked Questions About PCTFE Polymer
Common questions about PCTFE materials and applications
What is the difference between PCTFE and Kel-F®?
+PCTFE (Polychlorotrifluoroethylene) is the generic name for the fluoropolymer, while Kel-F® is a registered trademark of 3M Company for their PCTFE products. Our PCTFE materials are chemically equivalent to Kel-F® and meet the same ASTM D3275 specifications. We offer Kel-F®-equivalent PCTFE with identical performance characteristics at more competitive pricing.
Why is PCTFE the best moisture barrier material?
+PCTFE exhibits the lowest water vapor transmission rate (WVTR) among all transparent plastics, typically below 0.1 g/m²/24h. This is due to its dense molecular structure with chlorine atoms that create an exceptional barrier to moisture penetration. For pharmaceutical products sensitive to moisture degradation, PCTFE blister films provide superior protection compared to PVC, PVDC, or other barrier materials.
Can PCTFE be used for pharmaceutical packaging?
+Yes, PCTFE is widely used in pharmaceutical packaging applications. Our pharmaceutical-grade PCTFE meets FDA 21 CFR 177.1010 requirements for direct drug contact. PCTFE blister films are particularly valuable for moisture-sensitive medications, where superior barrier properties are critical for maintaining drug stability and extending shelf life. We provide complete documentation including USP Class VI testing for pharmaceutical applications.
How does PCTFE compare to PTFE?
+While both are fluoropolymers, PCTFE offers several distinct advantages over PTFE: 1) PCTFE is transparent while PTFE is opaque; 2) PCTFE has much better dimensional stability and lower creep; 3) PCTFE exhibits superior moisture and gas barrier properties; 4) PCTFE is harder and has higher mechanical strength. However, PTFE offers higher temperature resistance (up to 260°C vs 120°C for PCTFE) and slightly better chemical resistance. Material selection depends on your specific application requirements.
What machining capabilities do you offer for PCTFE?
+We offer comprehensive PCTFE machining services including CNC milling, turning, drilling, and precision grinding. PCTFE machines very well with sharp carbide tools and proper cutting parameters. We can achieve tolerances to ±0.005mm and surface finishes from standard machine finish to optical polish. For optical components, we provide specialized polishing to achieve >90% light transmission. Our engineering team can assist with design for manufacturability to optimize your PCTFE components for production.
What is the lead time for custom PCTFE parts?
+Lead times depend on part complexity and order quantity. Standard semi-finished PCTFE materials (sheets, rods, tubes) typically ship within 3-5 business days from our inventory. Custom machined parts generally require 2-4 weeks depending on complexity and quantity. Molded PCTFE components with new tooling typically require 6-8 weeks including tool fabrication. For urgent requirements, we offer expedited service with accelerated production schedules. Contact us with your specific requirements for accurate lead time quotations.
