Precision Polymer

Perfluoroelastomer (FFKM) is the most chemically resistant elastomer available and is effectively a rubber form of PTFE. Perlast® perfluoroelastomer grades provide other properties which prove most valuable in critical sealing applications where purity, high temperatures and retention of sealing force are paramount.

The Perlast® range of perfluoroelastomer materials are at the leading edge of polymer technology. They have been developed to offer superior sealing solutions with enhanced performance and improved functionality, which is proven in the field (see case studies).

Perlast

A unique range of fully organic elastomers ideally suited to thermal, dynamic and specific plasma processes where radical concentrations are generally lower or where inorganic filler systems are undesirable.

The Kimura® range of high performance elastomer materials utilize a controlled molecular architecture which provides a unique self-reinforcing polymer structure, providing improved chemical resistance without the use of inorganic fillers of any kind. This high purity material breaks new ground in elastomer technology, developed specifically for aggressive chlorine and CxFy based semiconductor applications.

Kimura® elastomers span the range of fluoro and perfluoro (FKM and FFKM) materials and includes unique hybrid elastomers, specifically developed by PPE, for the semiconductor industry, to offer a step-change in sealing performance, surpassing what has previously been achievable for fully organic materials.

The high purity of the polymer combined with the absence of inorganic fillers makes Kimura® materials suitable for processes involving lower feature sizes.

Kimura

Nanofluor® elastomers can be considered as hybrid materials, bridging a gap between the low cost of fluoroelastomer (FKM) and high cost of perfluoroelastomer (FFKM) polymer types.

The range includes a fully organic ultra-low outgassing material and an inorganic filled grade with unique nano-filler to reduce erosion rates. The nano-filled material provides a chemical inertness only seen in much more costly FFKM grades and been developed for plasma ash or resist strip, chlorine and CxFy based etch processes.

Nanofluor® grades provide some of the lowest trace metal contamination levels available from elastomer seals and ultra-low permeation rates.

Nanofluor

A range of metal detectable and X-ray detectable elastomer compounds designed specifically to meet the stringent demands of the pharmaceutical and food processing industries.

The Detectaseal® range includes FDA compliant grades of EPDM, Nitrile, Silicone and Fluorocarbon (FKM) compounds, plus USP Class VI certification for Silicone.  All materials in the Detectaseal® range are free from animal derived ingredients (ADI-free) and conform to EU regulations EC1935/2004 and EC2023/2006.

Available in blue and black, Detectaseal® O-rings have been tested and proven in use at leading pharmaceutical and food manufacturing plants. Fragments of Detectaseal® as small as 2mm can be identified by x-ray and in-line metal detection equipment in process lines.

Perlast® G74P

A translucent beige compound with semi-crystalline perfluoropolymer nano-filler, specially developed to meet the demands of the semiconductor and bio-analytical industries. Compatible with fluorine based chemistries and universally suitable for both wet and dry semiconductor processes including Lithography, Plasma, PVD, CVD, Etch, Stripping and Cleaning.Perlast® G67P combines a fully fluorinated polymer backbone, a fully fluorinated nano-filler system (no inorganic fillers) and a highly fluorinated cross-linking process, which results in a perfluoroelastomer with unrivaled purity and chemical resistance.Perlast® G67P has a significantly lower compressive modulus than traditional perfluoroelastomers, making it highly compliant. So for a given compression, it exhibits a low reaction force, this results in lower stress on the seal, which leads to longer life expectancy.Key Attributes Exceptionally pure - does not contain any inorganic fillers which may cause particulation problems. Excellent chemical and temperature resistance. Excellent mechanical properties. Extremely low out-gassing properties making it ideal for vacuum sealing applications. High sealing efficiency. High material compliance reduces surface permeation. Reduced first wafer effect. Lower cost of ownership. Typical Applications Dynamic seals Static seals Wafer-handling products
