Product Description
PFA rod is made from PFA resin and prepared by the technology of extrusion and molding. It can be machined into various sealing parts and electric components. It can be used at the temperature range of -200 ~ +260C degree
PFA (Polyfluoroalkoxy) owns excellent chemical stabilities, thermal properties and dielectric properties as PTFE. Good self-lubricating properties, flame resistance, and aging resistance. It has prominent folding endurance and stress cracking resistance. Its mechanical strength is 1.6 times as strong as PTFE.

PFA rod characteristics
- Appearance: PFA rod has a uniform texture with a smooth and flat surface, appearing transparent or semi-transparent.
- Excellent Plasticity: PFA shares the outstanding characteristics of PTFE, exhibiting higher mechanical strength than FEP at high temperatures. It can be easily processed using common thermoplastic forming methods.
- Excellent Corrosion Resistance: PFA is highly chemically stable and inert, resistant to most chemicals, acids, alkalis, water, and organic solvents, surpassing the properties of PVDF.
- Maintains Mechanical Strength over a Wide Temperature Range: PFA remains flexible and retains its toughness at extremely low and high temperatures. It has a maximum continuous operating temperature of 260°C, similar to PTFE, which is the highest among all fluoropolymers.
- Excellent Electrical Properties: PFA exhibits low and stable dielectric constants across a wide frequency range. It has extremely low and stable insulation loss coefficients and high volume resistivity. It also possesses high insulation breakdown strength.
- Non-flammability: PFA, like PTFE and FEP, is a non-flammable polymer with an oxygen index greater than 95%. It meets the UL94 standard with a V0 flammability rating.
- Excellent Weather Resistance: PFA retains its properties even when exposed to harsh weather conditions for extended periods.
- Non-stick and low friction: PFA itself is non-stick and has the ability to resist water, oil and other substances, with a smooth surface

PFA rod Features
PFA rod is made of imported high quality raw materials and processed by special technology. PFA rods retain most of the advantages of PTFE, while being able to undergo thermal melting due to reduced crystallinity, lower melting point and significantly reduced melt viscosity. Compared with FEP, it has superior resistance to high temperature and stress cracking. PFA rods also offer excellent flexibility and have higher mechanical strength than PTFE at high temperatures. High and low temperature resistance, long-term operating temperature range of -200ºC~ 260ºC. It has excellent chemical resistance, corrosion resistance to all chemicals, and low friction coefficient. It also has excellent electrical properties, with insulation that is not affected by temperature and excellent radiation resistance. Conforms to VO class flame retardant standard.
PFA rod is made of imported PFA resin, which has excellent chemical resistance, high temperature resistance, crack resistance and good transparency. Compared to other fluoropolymer tubes, PFA has higher polymer purity and higher continuous operating temperature.
