In the series of Perlast® FFKM elastomers are available in six rubber grades for O-rings and other types of rubber seals in the most challenging and critical industrial applications. See more on the page here about the six super-materials.
Betech is the strategic solution partner for PPE Perlast® elastomeric seals.
The Perlast series of perfluor rubber materials is at the forefront of polymer technology. The FFKM materials are developed by PPE – Polymer Precision Engineering Ltd – and offer superior sealing solutions with improved performance and functionality. The strong quality is proven by successful use in the market for 20 years.
Permanent and functional seals under both extremely hot and cold temperatures.
Perfluoropolymer generally offers high chemical resistance, but the Perlast grades G74S and G80A excel in exceptional resistance to both basic and acidic media.
Mechanical properties such as tensile strength, fracture strength and yield strength are particularly convincing.
The Perlast rubber products meet requirements and approvals for food contact, sanitary and medicinal applications: FDA, 3A 18-03 and USP Class VI.
Secure sealing materials in high-pressure applications with gas development or aggressive media in gas form, where leakage may occur rapid gas decompression – RGD
Perlast® FFKM materials have qualities and properties that make them exceptionally suitable for O-rings and other types of molded seals under the most challenging conditions in various locations such as process and processing equipment in food production, aggressive chemicals, very cold or hot applications – also under high pressure – in e.g. energy production, aircraft and satellite equipment.
