What is the difference matrial of PFA tube?
Normally we are use Daikin 230/231 and Chemours 451/951 PFA resins.
So let's summary of the differences between Daikin 230/231 and Chemours 451/951 PFA resins for tubing:
Daikin PFA (NEOFLON™ AP Series)
• AP-230:
◦ Industrial/high-purity grade, general-purpose semiconductor tubing.
◦ Good chemical resistance, transparency, and mechanical strength.
◦ Lower cost than 231SH; for standard ultra-pure fluid lines.
• AP-231SH:
◦ Semiconductor-grade (SH = Super High purity).
◦ Better flexibility, stress-crack resistance, and clarity than 230.
◦ Ultra-low ion/particle extractables; for critical semiconductor wet processes.
Chemours PFA (Teflon™ PFA)
• 451HP:
◦ High-purity grade, standard for semiconductor/chemical tubing.
◦ Melt flow rate (MFR) ≈ 2 g/10 min; stiffer, good for extrusion.
◦ FDA/SEMI-compliant; for ultra-pure chemicals and UPW.
• 951HP Plus:
◦ Ultra-high-purity grade (top-tier for semiconductors).
◦ MFR ≈ 12 g/10 min; easier processing, smoother inner surface.
◦ 60% lower permeation than standard PFA; minimal metal ion leaching (<1 ppb).
◦ For advanced nodes, high-concentration acids, and ultra-critical fluid systems.
| Brand | Grade | Purity Grade | MFR & Processing Performance | Core Feature | Main Application |
| Daikin | AP-230 | High Purity (General Grade) | Balanced melt flow, easy extrusion | Good chemical resistance & transparency, cost-effective | General chemical pipeline, ordinary high-purity fluid transportation |
| AP-231 | Super High Purity (Semiconductor Grade) | Excellent processing stability | Ultra-low ion & particle precipitation, outstanding stress crack resistance | Semiconductor wet process, high-standard ultra-pure liquid pipeline | |
| Chemours | 451HP | High Purity (Standard Semiconductor Grade) | Low MFR, rigid material, good molding property | Compliant with SEMI & FDA standards, stable comprehensive performance | Pharmaceutical, general semiconductor, ultra-pure water & chemical delivery |
| 951HP Plus | Ultra-High Purity (Top Grade) | High MFR, easy processing, smooth inner tube surface | Extremely low permeability, minimal metal ion leaching, best purity level | Advanced semiconductor process, high-concentration strong acid pipeline, ultra-critical high-purity fluid system |
Hope it's clear now.
