Need an FFKM alternative? 4 reasons to use Perlast® from PPE

Shortage of FFKM Perfluoroelastomers

You may be experiencing difficulties in obtaining some perfluoroelastomer (FFKM) grades; this is due to a number of factors which, when combined, have created a global supply chain problem.  A global shortage of polymer ingredients, sanctions on Russia, the energy crisis in China, high demand from specialist markets, the impact of Covid, and some manufacturing plants being offline, have all played their part.   More info

Perfluoroelastomers are well regarded as the ultimate high performance sealing material for the most challenging and critical applications.  So when the supply of FFKM seals is limited, it can severely interrupt your production schedules and impact profitability.  A reliable alternative, such as Perlast^®, complemented by our class leading manufacturing lead-times will minimise supply disruption and downtime.

Why Perlast^® is considered an excellent FFKM option?

Perlast^® compounds are premium perfluoroelastomers, comparable with other leading FFKM material grades.  There are some “low cost” FFKMs on the market, but these use budget ingredients to keep the price low.  Perlast’s polymer structure, characterisation and manufacturing process is optimised to deliver consistent high performance, high quality components, backed up by ISO9001/AS9100 accreditation and full batch traceability.

Perlast^® compounds have been used in demanding applications for over 20 years and consistently deliver high performance characteristics.

Why use Perlast^®?

Availability

Perlast^® perfluoroelastomers are not facing the same supply shortages that are affecting other FFKM grades.  PPE can manufacture Perlast^® O-rings and seals in lead-times of approximately 30 days; if we have stock, components can be shipped the same day.

Extreme temperature capability

Perlast^® materials provide a broad temperature range to offer a comprehensive Cold²Hot FFKM capability from -46°C (-51°F) up to +325°C (617°F).  Whatever the application or sealing challenge, there will be a Perlast^® material to suit, with consistent performance.

Excellent chemical resistance

Perlast^® perfluoroelastomers are proven to provide almost universal chemical resistance, even in some of the most inhospitable environments.  You won’t sacrifice any chemical resistance if you choose Perlast^® over other FFKMs - in certain applications Perlast^® outperforms competitor grades, especially in amines and steam.  More info
