FAQ

Q: 1.What are the performance differences between PFA tube and PTFE tube?

A: PFA can be melt-processed, has better flexibility and is easy to install; PTFE is hard, difficult to process and requires special techniques. Both have similar chemical stability, but PTFE is more stable at high temperatures, while PFA has better mechanical strength and creep resistance within 260℃.

Q: 2.What are the special requirements for using PFA flexible tubing in the semiconductor industry?

A: They need to meet ultra-high cleanliness standards, such as metal ion elution ≤10ppb, total organic carbon≤50ppb, and inner wall roughness Ra≤0.1μm to avoid contamination of high-purity media; they also need to pass SEMI F57 certification to adapt to precision processes such as wafer manufacturing.

Q: 3.How to connect PFA tubing? What are the common connectors?

A: Connection methods include hot-melt welding , ferrule connectors, and flange connection . Common connector materials are 316L stainless steel, Hastelloy and other corrosion-resistant materials.

Q: 4.Can PFA flexible tubing be used in medical infusion scenarios? What certification is required?

A: Yes. Medical-grade PFA hoses need to pass USP Class VI certification, which ensures no adverse reactions when in contact with human tissues and blood through strict biological test, ensuring infusion safety.

Q: 5.What are the advantages of multi-layer PFA tube compared with single-layer ones?

A: Multi-layer structures improve mechanical strength and pressure resistance through outer reinforcing materials, suitable for high-pressure scenarios or those requiring resistance to external impact; they also retain the corrosion resistance and cleanliness of the inner PFA layer, making them more suitable for complex industrial environments than single-layer structures.

Q: 6.How to judge whether PFA flexible tubing meet food-grade standards?

A: Food-grade PFA tube must provide FDA 21 CFR 177.1550 certification documents to ensure no harmful substances migrate when in contact with food; the appearance should be free of impurities and black spots, and the precipitate index can be verified through third-party testing to avoid using inferior products with recycled materials.
