PCTFE sheet, also named polychlorotrifluoroethylene sheet or Kel-F PCTFE sheet, is a rigid fluoropolymer known for very low gas permeability, near-zero moisture absorption, and stable dimensions across wide temperature changes. Peflon PCTFE sheet is made from trusted Neoflon resin and supports applications such as cryogenic valve seats, pump parts, chemical sight windows, and semiconductor carriers. As a manufacturer in China with controlled production lines, thickness calibration, and full TDS documentation, we help OEM engineers and buyers secure consistent PCTFE sheet quality for critical sealing and barrier designs. Share your drawing or application details, and our team will guide you to the right PCTFE sheet grade.
PCTFE sheet offers the combination of low gas permeability, near-zero moisture absorption, and stable mechanical strength across a wide temperature range. These properties help polychlorotrifluoroethylene sheet maintain tight tolerances in cryogenic valves, pump components, and moisture-sensitive assemblies. You can use this material when your design requires a rigid, barrier-grade fluoropolymer with predictable behavior over time.
| Property | Typical Value / Behavior | Notes for PCTFE Sheet Selection |
|---|---|---|
| Service Temperature Range | approx. –240°C to +190°C | Ideal for cryogenic PCTFE sheet applications |
| Gas Permeability | Very low | Suitable for barrier assemblies & sealing parts |
| Moisture Absorption | Near zero | Supports dimensional stability in humid systems |
| Compressive Strength | High, low deformation under load | Good for valve seats, seals, precision parts |
| Tensile Strength | High relative to other fluoropolymers | Better rigidity vs PTFE sheet |
| Coefficient of Thermal Expansion | Low | Reduces shrinkage in cryogenic systems |
| Chemical Resistance | Excellent to most industrial chemicals | Fits chemical plant equipment |
| Flammability | Non-flammable / very low flammability | Suitable for aerospace & safety-critical designs |
| Electrical Properties | Good dielectric strength | Useful for semiconductor & electronic parts |
| Transparency | Clear to translucent (grade-dependent) | Works for sight windows & inspection covers |
PCTFE sheet maintains stable dimensions under temperature changes and mechanical load, making it suitable for tight-tolerance components in cryogenic valves and semiconductor carriers.
PCTFE sheet provides clean edges and predictable chip formation during CNC machining. This helps reduce scrap and supports the production of accurate sealing parts.
Compared with PTFE sheet, PCTFE sheet has higher stiffness, which is useful for pump parts, barrier plates, and structural fluoropolymer components.
PCTFE sheet shows low deformation under constant stress, resulting in better long-term performance in valve seats and gaskets.
Polychlorotrifluoroethylene sheet provides one of the lowest moisture vapor transmission rates among unfilled fluoropolymers, supporting moisture-sensitive assemblies.
Peflon offers several PCTFE sheet categories to help you choose the right material for your application. Each polychlorotrifluoroethylene sheet is produced with steady thickness, clean surfaces, and reliable resin quality, giving you a stable base for machining valve seats, pump parts, sight windows, and barrier panels. You can select from standard, high-clarity, barrier-grade, and machining-grade PCTFE sheet options depending on your system needs. Tell us your size or drawing, and we will recommend the best match for your design.

PCTFE Sheet is used for parts that need strong clarity, low moisture pickup, and high chemical resistance. Many buyers choose it for cold-room seals, lab covers, viewing windows, and chemical parts because it stays stable and easy to clean.
PCTFE Sheet works better than PTFE when you need strong dimension control at very low temperatures. It stays firm and does not soften or change shape as easily, which is useful for valves, gaskets, and cryogenic parts.
Yes. A PCTFE Sheet can be machined with most standard cutting tools. It creates clean chips, has good edge strength, and allows smooth milling or drilling. Many machine shops use it for tight-tolerance parts.
A PCTFE Sheet has strong resistance to many acids, oils, fuels, and lab chemicals. This makes it suitable for chemical tanks, pump parts, and protective covers where long service life is needed.
PCTFE Sheet can be made in thin or thick options based on your needs. Most buyers choose sheets from 0.5 mm to 25 mm, and larger sizes can be cut to order. Custom cuts and special formats are also possible.
You may also need other materials that work well with your PCTFE Sheet projects. Many buyers look for options when they face limits in heat resistance, pressure strength, or budget. To help your team choose the right match, we offer PTFE sheets, PVDF sheets, FEP films, and engineering plastics that fit different chemical and temperature needs. These products let you compare performance and pick the best choice for your parts, tools, or equipment builds.
