About PCTFE material

PCTFE, the full name is Polychlorotrifluoroethylene, also known as PTFCE, is a thermoplastic chlorofluoropolymer. It can be shaped into sheet, film, rod, and tube. Compared to PTFE (Teflon), PCTFE offers higher strength, meantime, PCTFE is resistant to the attack of most chemicals and oxidizing agents, due to the presence of high fluorine content.

PCTFE material offers the highest limiting oxygen index and excellent chemical resistance, it is also exhibits properties like zero moisture absorption and non-wetting. It can work well at temperatures from -240 to 200 °C, meantime, it offers great dimensional stability and a low coefficient of thermal expansion. Therefore, PCTFE is an indispensable material in aerospace, electrical, medical, cryogenic valve, and nitrogen generation applications.

PCTFE material can be processed by injection molding, extrusion, and compression molding. The frequently used profiles are sheets, rods, films, tubes, etc.

Frequently Asked Questions about Polypropylene (PP) plastic

PCTFE, often known as Polychlorotrifluoroethylene, is a thermoplastic chlorofluoropolymer. It is the most demanding thermoplastic material due to its unique capability of maintaining its physical properties at extremely low operating temperatures. It has exceptional mechanical properties and the lowest coefficient of thermal expansion of any unfilled fluoropolymer.

There are three methods to bond PCTFE:

Thermal Adhering Technology

You need to use heat gun or a hot plate to heat PCTFE to 215 °C. Pressing two PCTFE parts together when it begin to be soft.

Adhesion Agent or Glue

You should choose the fluoro rubber adhesive or Epoxy fluorine adhesive to adhere PCTFE parts. But you need clean the surfacec of adhensive area firstly.

Solvent Cementing

You should choose the chloro-carbon solvent, for example Chloroform, carbon tetrachloride, but it is toxic, you should clean the surfacec of adhensive area firstly.

PCTFE is often used in valves due to its unique mechanical properties compared to other fluoropolymers. Its low permeability prevents liquids or gases from passing through easily. The exceptional dimensional stability at extreme temperatures ensures the valve’s seats and seal functions work well in any condition.

PTFE, or polytetrafluoroethylene, is a popular fluoropolymer known for its low friction coefficient and excellent chemical resistance. On the other hand, PCTFE, or polychlorotrifluoroethylene, is another fluoropolymer that is harder and stronger and has better mechanical properties than PTFE. With even better chemical resistance, PCTFE is a replaceable PTFE material used in various applications.

PCTFE, or polychlorotrifluoroethylene, is one of the most popular trade names that is manufactured under various trade names. Neoflon PCTFE from Daikin Industries LTD is the prominent producer of the product. Other brand names include Voltalef®, Kel-F®, Neoflon®, Aclar®, Halon®, Fluon®, Hostaflon®, Plaskon®. Different companies use these names to sell PCTFE for various uses.

The chemical formula of PCTFE (CF₂CClF). Here, “n” typically is the number of monomer units in the polymer molecule, called chlorotrifluoroethylene or CTFE. It is chemically similar to PTFE with a different chemical structure. It uses chlorine instead of just fluorine, which gives it a strong base in the structure.

Monochlorotrifluoroethylene is the raw material for the production of PCTFE. The free radical polymerization of chlorotrifluoroethylene forms this thermoplastic. The polymerization process can be done in various ways, including suspension, emulsion, bulk, or solution.

Yes, PCTFE is uniquely compatible with liquid oxygen. This means it shows excellent resistance to ignition and burning with the O₂ components. This makes it perfect for use in demanding environments where exposure to oxygen and extreme conditions requires materials with high safety.

PEEK and PCTFE are high-performance thermoplastics combining excellent mechanical and chemical properties. PEEK offers superior structural strength and dimensional stability across a broad operating temperature range. PCTFE also shows chemical stability with good flame and temperature resistance. However, it has a lower coefficient of thermal expansion compared to PEEK.

Yes, PCTFE is a high-grade thermoplastic that can easily be injection molded to produce precision parts. The material’s high-quality mechanical and chemical properties, including flame and chemical resistance, produce similar characteristics in the molding process used in various demanding applications. Even the low melt viscosity of PCTFE allows it to bear the demands of the molding process without any degradation of the material.

The operating temperature for the PCTFE valve seat varies depending on various sources. It operates in a wide array of temperature ranges that can go up to 500°F. It can even maintain its stability within the lowest temperature range of -250°C with a slight degradation of up to 1%. At -250°C, PCTFE shrinks a little bit.

Victrex CT™ 200 is the absolute alternative to PCTFE. It is a high-performance thermoplastic PEEK polymer that is suitable for any demanding application. It ensures high tensile strength and better stability to the pulling or stretching compared to PCTFE. Plus, it is coupled with better thermal stability at extreme temperatures and even minimizes shrinkage at low temperatures.

PCTFE is used in a variety of applications. This includes cryogenic, aerospace, medical, chemical applications, and so on. You will also find it in various laboratory instruments and nuclear services. It can be made into films to protect items from moisture, as seen in packaging or LCD screens.

Yes, PCTFE shows excellent physical and mechanical stability to extreme temperatures, up to 248°F or 120°C. However, it can withstand a maximum peak temperature of +200°C for a short time without any degradation.

No, PCTFE shows low to zero moisture absorption capability. This is mainly due to the chemical structure of PCTFE, which makes it highly resistant to moisture agents. This exceptional quality of the material helps maintain its properties in humid conditions.

Yes, Polychlorotrifluoroethylene shows excellent transparency and can be made into thin, transparent sheets that look like glass. That’s why it is a useful material to use in sight glasses. Its reduced crystallinity and structural stability make it ideal for making transparent products used in films and thin sheets.
