What Is PCTFE Sheet?
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.
| 재산 | 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 | 높은, low deformation under load | Good for valve seats, seals, precision parts |
| 인장 강도 | High relative to other fluoropolymers | Better rigidity vs PTFE sheet |
| Coefficient of Thermal Expansion | 낮은 | Reduces shrinkage in cryogenic systems |
| Chemical Resistance | 훌륭한 to most industrial chemicals | Fits chemical plant equipment |
| 가연성 | 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 |
✔ Dimensional Stability
PCTFE sheet maintains stable dimensions under temperature changes and mechanical load, making it suitable for tight-tolerance components in cryogenic valves and semiconductor carriers.
✔ Machinability
PCTFE sheet provides clean edges and predictable chip formation during CNC machining. This helps reduce scrap and supports the production of accurate sealing parts.
✔ Rigid Structure
Compared with PTFE sheet, PCTFE sheet has higher stiffness, which is useful for pump parts, barrier plates, and structural fluoropolymer components.
✔ Low Cold Flow / Creep
PCTFE sheet shows low deformation under constant stress, resulting in better long-term performance in valve seats and gaskets.
✔ Barrier Performance
Polychlorotrifluoroethylene sheet provides one of the lowest moisture vapor transmission rates among unfilled fluoropolymers, supporting moisture-sensitive assemblies.
