Our Factory

PCTFE resin is a key product of our national strategic emerging industries. In the past, our country relied heavily on import.But in recent years,our domestic enterprises have successfully achieved PCTFE resin made in China, filling the gap in the domestic field of ultra-low temperature corrosion-resistant materials, solving the problem of tensile fracture of fluoropolymers at low temperatures, and promoting the domestic substitution process of key materials.

PCTFE is a thermoplastic fluoropolymer produced primarily from CTFE. It is a crystalline polymer with a melting point of 215℃ and a density of 2.13 g/cm³. Its extreme low-temperature performance, excellent gas barrier properties, and strong oxidation resistance make it a promising choice for applications in cryogenic sealing applications such as liquefied natural gas and liquid nitrogen.PCTFE resin made in China brings many benefits across various fields.

Characteristics

Continuously operating temperature -196℃ to 125℃, with short-term withstand temperatures up to 250℃

High transparency, impermeable, and excellent gas barrier properties

Good adhesion to metals, making it easy to create various composite materials

High mechanical strength, meanwhile with good elastic recovery

Good resistance to most chemicals

Applications of PCTFE resin made in China

1. Mechanical field:

Excellent cold flow resistance and high compressive strength, making it suitable as a structural material for mechanical equipment. Its excellent gas barrier properties make it suitable as a sealing material for high-vacuum systems, as well as for piping and valves in liquefied gas tank trucks. Its transparency allows for the manufacture of transparent piping and levels. Furthermore, its excellent cold flow resistance, creep resistance, wear resistance, dimensional stability, and machinability enable the manufacture of high-precision mechanical parts, such as valve seats, self-lubricating gears and bearings, O-rings, and brakes.

2. Chemical field:

PCTFE resin is mainly used for corrosion-resistant components in chemical equipment, such as pipes, valves, valve seats, gears, bearings, diaphragms, gaskets, reaction vessels, storage tanks, centrifuges, etc.

3. Electronics and electrical field:

PCTFE resin is used to manufacture components for various electronic and electrical equipment, such as bases, sockets, coil shafts, connectors, circuit breakers, switches, printed circuit boards, etc. It is also widely used in the manufacture of wire sheathing materials and cable sheaths.

PCTFE has the same water resistance as PTFE, maintaining its quality after immersion in water at 60℃ for 900 hours, meaning its product's dimensions are stable in water or high humidity environments. PCTFE film has the lower water vapor permeability rates among plastics, making it suitable as a moisture-proof packaging material for precision electronic components. However, PCTFE film has poor heat-sealing properties and requires corona discharge treatment followed by lamination with hot melt adhesive.

4. Optics and Nuclear Industry:

PCTFE can be used to manufacture optically transparent components and radiation protection products. Its high transparency and low ultraviolet absorption rate give it immense potential in the optical field. At the same time, its radiation resistance makes it an important protective material in the nuclear industry.
