What is PCTFE?
PCTFE is a high-performance engineering plastic and a type of fluoropolymer. Compared with PTFE, it has a much lower gas permeability—only one-tenth that of PTFE. Its operating temperature ranges from -400°F to 379°F, making it extremely resistant to low temperatures and ideal for your LNG projects. It also offers excellent dimensional stability and the highest hardness, making it a preferred material in the semiconductor industry.
HANSA has over 20 years of experience producing PCTFE sheets, offering professional manufacturing expertise and one-stop engineering plastic solutions. Using both compression molding and machining processes, we ensure that our PCTFE sheets meet standards for airtightness, dimensional stability, and hardness.

Review
-
The packaging was intact, and the products were inspected by the HANSA team to ensure quality compliance. I will definitely repurchase PCTFE sheets from HANSA, as my project is large.
-
I initially planned to source PCTFE sheets from a manufacturer and have them processed elsewhere. However, HANSA was able to provide fully machined finished parts directly—and at a more competitive price. This saved me significant time and cost. HANSA is a highly reliable company.
-
I had just secured this project and was not familiar with the material. HANSA’s technical team was very professional and recommended the most suitable material at a reasonable price.
-
The sealing rings made from PCTFE have excellent gas tightness—no leakage at all—and they prevent contamination of my chemicals. The parts processed by HANSA also fit my equipment perfectly.
-
HANSA is a trustworthy manufacturer. I have been working with them for 7 years, and every shipment is delivered on time with excellent packaging, which helps me maintain my own customer relationships.

These properties are unmatched by other fluoroplastics. If your project is in the LNG or semiconductor industry, PCTFE is one of the best materials for seals and precision components.
Yes. Especially for LNG applications, we perform slicing inspections on each PCTFE sheet to ensure there are no voids before shipment. Voids can affect sealing performance, cause project delays, and increase costs.
HANSA ensures consistent quality across different production batches. All products undergo strict quality inspection. As a professional manufacturer of fluoroplastics like PCTFE, HANSA maintains a high level of expertise and process control.
HANSA controls the thickness tolerance within ±0.05 mm.
No. Thanks to its excellent dimensional stability and strong creep resistance, PCTFE does not easily deform or crack during CNC machining. You can confidently machine it yourself, and HANSA also offers CNC services for finished parts.
The low-temperature shrinkage rate is very low, typically between 1.5% and 2%.
Yes. HANSA conducts low-temperature cycling tests in collaboration with clients to ensure stable performance under alternating temperature conditions.
PCTFE has the lowest gas permeability among all fluoroplastics. Typical values are:
- Oxygen permeability: ~0.5–1.5 Barrer
- Nitrogen permeability: ~0.2–0.8 Barrer
- Helium permeability: ~5–10 Barrer
Yes. PCTFE offers high compressive strength, low gas permeability, and excellent low-temperature resistance. Typical applications include LNG valves, gas cylinders, and cryogenic sealing components.
