Perlast ® – in a class of its own For some applications there is no alternative to a perfluoroelastomer (FFKM/FFPM). In these cases it is good to know that you can trust in the extraordinary Perlast® compound from COG. As a state-of-the-art product Perlast® combines the chemical and thermal resistance of PTFE with the elastomer properties of an FKM. It is used where other elastomers cannot do the job and maximum reliability is required. The Perlast® range of elastomers offers performance characteristics that span the most demanding of applications across various industries. Perlast‘s flexibility provides you with a number of advantages. The combination of in-house tooling, extensive range of materials and rapid production means, that nonstandard O-Rings and custom components can be supplied just as easily as BS/AS or other standard sizes – with exceptionally short lead times. Special Perlast® compounds are compliant with FDA, USP Class VI and clean room requirements which are used e. g. in pharmaceutical and food industries. Advantages of Perlast ®: • Excellent all-round performance with universal capability • Maximum chemical resistance of all elastic sealing materials • High temperature stability up to +327 °C, depending on the grade used • Low compression set • Excellent vacuum performance • Wide range of approvals/ licences • Ring diameter up to 2000 mm possible When it matters … ty ali qu ium 867 em ce 1 r P sin Perlast ® – A range of products for various applications Industrial applications: Perlast ® G75TX The FFKM compound Perlast® G75TX sets new standards.

Compatible with fluorine based chemistries and universally suitable for both wet and dry semiconductor processes including lithography, plasma, PVD, CVD, Etch, stripping and cleaning. G67P features extremely low outgassing properties, making it ideal for use in vacuum applications. Because of the very small filler material particles it is also suitable for very shortwave length laser light applications. Same characteristics as G67P, but this elastomer differs in some points, e. g.: the hardness, tensile strength, elongation at break, modulus and compression set. Perlast® G75H is a synthetic pure compound, specially developed for the semiconductor and vacuum industry. It is suitable in an operating temperature range from -15°C up to +320°C. This compound has an excellent resistance to aggressive oxygen and fluorine based plasmas. Because of its extremely low outgassing properties PERLAST® G75H is used in the vacuum technology applications.

In a production process efficiency is essential and second only to quality assurance. A reduced life-span and shorter utilisation time of an unsuitable O-Ring increases the maintenance rate and this causes high installation costs and production downtimes.
