Description

1. Product Description

PCTFE (Polychlorotrifluoroethylene) resin is a high-performance fluoropolymer known for its exceptional moisture barrier properties, ultra-low gas permeability, and excellent clarity. It offers outstanding chemical resistance, dimensional stability, and low outgassing characteristics, making it ideal for precision molding applications. With a continuous service temperature range from -200°C to +150°C, PCTFE resin is widely used in critical environments where stability and purity are essential. Its non-flammable, non-toxic nature also complies with demanding safety standards such as FDA and ASTM.

2. Product Applications

PCTFE resin is suitable for use in the following industries and applications:

  • Cryogenic components (valves, seals, O-rings)

  • High-performance barrier films for moisture-sensitive electronics and pharmaceuticals

  • Semiconductor and electronic parts

  • Precision medical components

  • Aerospace insulation and components

  • Chemical processing equipment

  • Transparent mechanical parts requiring optical clarity and dimensional stability

4. FAQ – Frequently Asked Questions

Q1: What makes PCTFE resin different from PTFE or FEP?
A1: PCTFE has significantly lower gas permeability, better dimensional stability, and higher tensile strength, making it ideal for moisture- and air-sensitive applications.

Q2: Can PCTFE resin be injection molded?
A2: Yes, it has excellent processability for precision injection and compression molding.

Q3: Is PCTFE FDA approved for food or medical use?
A3: Yes, high-purity grades of PCTFE resin comply with FDA regulations and are suitable for medical applications.

Q4: What’s the temperature range for PCTFE use?
A4: PCTFE maintains performance from -200°C to +150°C.

Q5: Is PCTFE resistant to radiation or UV?
A5: PCTFE offers good resistance to UV and moderate resistance to gamma radiation.

Q6: How does PCTFE perform in cryogenic conditions?
A6: It retains mechanical integrity and sealing performance even at extremely low temperatures, making it ideal for cryogenic valves and gaskets.

Q7: Can PCTFE be used as a transparent barrier film?
A7: Yes, it is widely used for transparent films in pharmaceutical and electronics packaging due to its ultra-low moisture permeability.

Q8: What is the shelf life of PCTFE resin?
A8: If stored properly in dry conditions, it has an indefinite shelf life without performance degradation.

Q9: Is PCTFE recyclable or reusable?
A9: It can be reprocessed under controlled conditions, but recycling is less common due to its high-performance nature.

Q10: What processing techniques are suitable for PCTFE resin?
A10: Suitable methods include injection molding, compression molding, extrusion, and machining of molded parts.
