High-Purity Fluoropolymers & SEMI F57
Convena Polymers supports the selection of high-purity fluoropolymers for ultrapure-water (UPW) and liquid-chemical distribution systems used in semiconductor manufacturing. We can provide grade- and batch-specific SEMI F57 test documentation for applicable materials on request.
High-purity fluoropolymers for semiconductor fluid handling
High-purity PFA and PTFE are used for tubing, valves, fittings, vessel and pipe linings, and other wetted components where chemical resistance, low extractables and reproducible material performance are critical. Material selection must be based on the actual grade, fabrication route, medium and operating conditions.
High-purity PFA
Melt-processable PFA for chemical-liquid tubing, sheet and valve linings. Discuss NEOFLON™ PFA and other suitable high-purity grades with our team.
High-purity PTFE
PTFE for demanding semiconductor components, including paste-extruded tubing, compression-moulded components and other high-purity applications.
What “SEMI F57 tested” means
SEMI F57 is a specification for high-purity polymer materials and components used in UPW and liquid-chemical distribution systems. A SEMI F57 test claim applies only to the material grade, tested batch and test specimen identified in the relevant analytical report. It is not a blanket qualification for every grade in a product family or every finished component.
| Specification and methods | SEMI F57, supported by SEMI F40 for sample preparation and analytical procedures, and SEMI F104 for particle-contribution measurement. |
|---|---|
| UPW extraction | Sample exposure in ultrapure water at +85 °C for 168 hours (7 days). |
| Trace metallic contamination | Leachable metals: 22 elements, including Fe, Cu, Ni, Zn, Na and Ca; stated limit ≤ 5 µg/m². |
| Ionic contamination | Leachable anions and cations: eight ion species, including F⁻, Cl⁻, NO₃⁻ and SO₄²⁻. |
| Other reported criteria | Total organic carbon (TOC), particle contribution to UPW and wetted-surface roughness (Ra). |

Documentation and qualification support
For the applicable tested material, an SEMI F57 compliance or analytical test report identifying the laboratory, test date, report number, tested grade and batch is available on request. Ask us for the current TDS, SDS, test information and documentation needed for your qualification process.
