| What is the nature of PFA? PFA has similar properties to FEP, but because its melt viscosity is lower than PTFE, it can be used at operating temperatures up to +260°C while maintaining meltability. PFA has several unique properties that make it suitable for medical, chemical and electrical applications, among others. PFA has the following characteristics :· Extremely high operating temperature up to +260°C · Extremely low operating temperature up to -200°C · Non-stick characteristics · Low friction surface · Very high resistance to chemicals and solvents · Very high resistance · Biocompatibility |
| What are the advantages and disadvantages of PFA? In addition to the unique properties of fluoropolymers, PFA has the following advantages :· Continuous operating temperature of +260°C - in addition to PTFE, PFA has the highest operating temperature of all fluoroplastics · Welding and remolding potential · Protection against harsh environmental conditions · Insulation against electricity, heat, chemicals and solvents · Good permeability resistance · High purity grades can be provided · High clarity PFA has similar physical and chemical properties to PTFE, but it has 10 times the flexural life of PTFE and lower permeability. PFA has excellent cracking and stress resistance and low friction coefficient. The main disadvantage of PFA is that it is more expensive than PTFE or FEP. |
| What does the PFA of the PFA do? PFA is widely used in applications that require higher purity, excellent chemical resistance, and high operating temperatures, such as medical pipes to heat exchangers, semiconductor baskets, pumps and accessories, and valve liners. PFA is ideal for temperature-sensitive applications. It is usually thermoformed to form a closed end cap that can safely shrink on temperature-sensitive materials without causing damage |
| Products have a wide range of applications, can be used in electroplating, textile, paper, food machinery, transportation, medical, coal, chemical industry. Other trades |
