FFKM (Perfluoroelastomer) O-Rings Manufacturer & Bulk Exporter to Spain
Ultra-high purity perfluoroelastomer O-rings with continuous thermal resistance up to +327°C and extreme plasma resistance for semiconductor wafer processing.

45,000 sq.ft customs-bonded facility equipped with 50T–500T vacuum moulding presses, in-house mixing mills, and Class 5/7 cleanrooms.
Precision Polymer Engineering for Critical Industrial Operations
Manufactured within our specialized ISO Class 5 and Class 7 cleanroom suites at the Chennai MEPZ-SEZ facility, Horiaki FFKM O-rings deliver semiconductor-grade ionic purity, ultra-low particle generation, and negligible outgassing in high-vacuum processing chambers. Every compound is compounded in-house using virgin monomers cross-linked via proprietary triazine or advanced peroxide curatives.
In harsh dry-plasma etching, chemical vapor deposition (CVD), and atomic layer deposition (ALD) semiconductor processes, our HK-FFKM 327 grade exhibits superior resistance to active fluorine, chlorine, and oxygen RF plasma radicals (including CF4, NF3, SF6, and Cl2). Mass-spectrometry ICP-MS analysis confirms metallic ion extractables below 0.1 parts per billion (ppb), preventing substrate contamination during sub-10nm wafer fabrication.
For international industrial processing plants, refineries, and offshore oil and gas production, Horiaki FFKM seals eliminate catastrophic seal degradation caused by aggressive amine corrosion inhibitors, sour gas (H2S), superheated steam, concentrated inorganic acids, and aromatic ketones. With an operational lifespan up to 10x longer than standard FKM (Viton), our FFKM O-rings minimize unplanned turnaround shutdowns and critical equipment failures.

Frequently Asked Questions
Common questions regarding compound formulations, tooling lead times, and export logistics.
What is the difference between standard FKM (Viton) and FFKM (Perfluoroelastomer)?
FKM contains a fluorinated hydrocarbon backbone with residual hydrogen atoms. FFKM has a fully fluorinated backbone where every hydrogen is replaced by fluorine, yielding chemical inertness and temperature resistance (+327°C vs +200°C) virtually identical to PTFE while retaining complete elastomeric memory.
Can Horiaki provide material test reports and lot traceability for FFKM consignments?
Yes. Every export lot is shipped with an authentic EN 10204 3.1 Material Test Report (MTR) detailing batch specific gravity, Shore A hardness, tensile strength, elongation at break, and MDR rheometer cure curves.
What is the typical production lead time for custom FFKM O-ring dimensions?
Standard AS568 and ISO 3601 sizes are dispatched from inventory or molded within 5–7 business days. Custom non-standard sizes utilize our in-house CNC wire-EDM tooling shop with 7-day rapid mold manufacturing.
How are Horiaki FFKM O-rings packaged for international shipment?
Cleanroom FFKM O-rings are cleaned with isopropyl alcohol, baked, and double heat-sealed in polyethylene bags inside our ISO Class 5 cleanroom with individual lot traceability barcodes and shelf-life expiration labels.
What is the ocean and air transit time from Chennai Port (INMAA)?
Urgent prototype evaluations dispatch via DHL/FedEx Express Air within 48–72 hours. Ocean container consignments sail directly from Chennai Port (INMAA): Dubai (5–7 days), Hamburg/Rotterdam (24–28 days), Houston/New York (26–32 days).
