PFA Ball | Perfluoroalkoxy Ball | 5mm to 310mm | Highest Purity Fluoropolymer Ball
HEMSUN ENGG. INDUSTRIES manufactures PFA Balls — Perfluoroalkoxy Balls — from 5mm to 310mm diameter. PFA is the highest-purity fluoropolymer material — PFA Balls match full PTFE chemical resistance across all chemicals pH 0 to 14 while being melt-processable for superior surface finish, smoother bore, and ultra-low extractable contamination compared to compression-molded PTFE. PFA Balls are the global standard for semiconductor ultra-high-purity chemical delivery, pharmaceutical water-for-injection systems, and precision analytical instrumentation. ISO 3290 Grade G10. Exported globally.

Manufacturing Process
PFA Balls are CNC-machined from extruded PFA rod stock in dedicated equipment to maintain ultra-high purity and prevent cross-contamination. PFA's melt-processable nature produces a denser, smoother, non-porous surface with fewer PTFE particle generation concerns compared to compression-molded PTFE balls.
Compliance & Standards
IEC registered. FDA 21 CFR compliant. ISO 3290 Grade G10. Highest purity fluoropolymer — ultra-low extractables for semiconductor and pharmaceutical. Service temperature +260°C (higher than FEP). Regular export to UAE, Germany, USA, Japan, Singapore, Brazil, Turkey, and Middle East.
Frequently Asked Questions
Why is PFA Ball considered higher purity than PTFE Ball for semiconductor use?
PFA is melt-processable — producing a denser, smoother, non-porous surface with fewer PTFE fine particles generated during valve cycling. In semiconductor ultra-high-purity applications, PTFE compression-molding porosity and particle generation are concerns; PFA's melt-processed surface eliminates this, making PFA Balls the industry standard for semiconductor chemical delivery valve balls.
What is the largest PFA Ball you manufacture?
We manufacture PFA Balls up to 310mm diameter — one of the widest size ranges for PFA Balls available globally.
What is the difference between PFA Ball and FEP Ball?
Both are melt-processable fluoropolymers with similar chemical resistance. PFA has a higher service temperature (+260°C vs FEP's +200°C) and is considered the higher-purity choice for semiconductor WFI and pharmaceutical applications. FEP is transparent; PFA is semi-transparent. Both available from HEMSUN in 5mm to 310mm diameter.
