PP PFA Cleaning Tank Material Comparison
Compare PP PFA cleaning tank materials for chemical resistance, heat resistance, costs, and applications in ultrasonic cleaning and semiconductor processes.
Why Is a Plastic Tank Required?
In acidic cleaning solutions and high-concentration chemical environments, stainless steel may corrode and cause ion contamination.
PP materials can provide better chemical resistance in acidic and alkaline solutions.
Common applications include semiconductor wafer cleaning, chemical liquid circulation systems, and acid etching processes.
Characteristics and Applications of PP Materials
Resistant to acids and alkalis, but not resistant to strong oxidizing agents such as nitric acid and aqua regia.
Lower cost and suitable for weld fabrication, commonly used for general acid and alkaline cleaning tanks.
Heat deformation temperature is around 90°C, suitable for cleaning solutions operated at room temperature to approximately 80°C.
Characteristics and Applications of PFA Materials
Excellent chemical inertness and resistant to almost all acids, alkalis, and solvents.
Can withstand long-term operation at 150°C. The surface is extremely smooth and not easily contaminated.
Suitable for ultrapure chemical solutions, semiconductor wet processes, and high-purity electronic cleaning lines.
PP vs PFA Material Comparison
Acid and Alkali Resistance
PP tanks provide good resistance to medium-strength acids and alkalis.
PFA tanks provide excellent resistance to almost all chemicals.
Heat Resistance
PP tanks are suitable for operating temperatures below approximately 90°C.
PFA tanks are suitable for operating temperatures below approximately 150°C.
Cost
PP tanks have a lower material and fabrication cost.
PFA tanks have a higher cost.
Processability
PP is easier to weld and form, making it suitable for general tank fabrication.
PFA is more difficult to process and requires specialized equipment.
Recommended Industries
PP tanks are commonly used for general metal and hardware cleaning.
PFA tanks are commonly used in semiconductor, optoelectronics, and chemical liquid tank applications.
PP and PFA are two common plastic tank materials used in ultrasonic cleaning equipment.
PP tanks offer good acid and alkali resistance with excellent cost efficiency, making them suitable for general metal parts and industrial cleaning applications. PFA tanks provide extremely high chemical stability and heat resistance, allowing them to withstand strong acids, strong alkalis, and high-purity chemical environments. They are especially suitable for semiconductor and electronic-grade processes.
