In order to simplify the selection for your appropriate applications the most popular Perlast® compounds are introduced here in short form.
The major product within the product family is highlighted.


Perlast® G75B: „The Top All Rounder“

Perlast® G75B has been specially formulated to provide increased acid resistance by eliminating fillers that are prone to acid attack and optimising the polymer structure. In addition, this perfluoroelastomer has low permeability and as a result, it is less prone to swelling, leading to extended in-service performance in, for example, valves, pumps and mechanical seals.
A high modulus makes G75B resistant to extrusion and ideal for use in high pressure environments. In addition, the low long-term compression set provides a high mean-time between maintenance cycles in hot chemically aggressive environments.  Perlast® G75B is suitable for both dynamic and static applications and can be moulded into O-Rings and custom shapes. Also suitable for vacuum applications. Temperature stability up to 325 °C. Available in the hardness of 78 °IRHD / Shore A 79.

Perlast® G75H

Perlast® G75H incorporates a novel reinforcement system which produces a synthetically clean compound formulated for minimum particle generation combined with excellent resistance to aggressive oxygen and fluorine based plasmas. Extensive chemical and steam resistance. Particularly suitable for applications in the semiconductor industry and also an optimal choice for dynamic applications. Because of its extremely low outgassing properties PERLAST® G75H is used in the vacuum technolgy. Specially developed for Plasma and Gas Deposition applications including ashing, etching, HDPCVD, PECVD, SACVD.
Particularly suited for use in applications which require exposure to temperatures of up to 320°C (continuous use temperature approx. 260 °C ) combined with excellent mechanical properties. Available in the hardnesses of 75 °IRHD.

Perlast® G74P, G67P

An ultra-pure grade of translucent perfluoroelastomer. This 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® G74P 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 unrivalled purity, chemical resistance and mechanical properties.
Perlast® G74P exhibits extremely low out-gassing properties, making it ideal for use in vacuum applications. Because of the very small filler material particles it is also suitable at very shortwave laser light. Available in the hardnesses of 64 and 75 °IRHD / Shore A 64 and 74.

Perlast® G75S, G74S

Pure white multi-purpose perfluoroelastomer compound for Life Science applications.
Perlast® G75S is an all round material that can be used for all types of applications requiring FDA and USP Class VI compliance. It is suitable for use in all product contact applications including dry, aqueous and fatty media.

Unlike other FDA compliant elastomers, Perlast® G75S is thermally stable at higher temperatures, and is ideal for use in applications which require exposure to temperatures up to 310°C (590°F) making it suitable for use in Stage II Sterilization processes.
Perlast® G75S is suitable for both dynamic and static applications and can be moulded into O-Rings and custom shapes.

Perlast® G75S has been specifically developed to cope with a wide range of process media, potent active pharmaceutical ingredients (API's) and aggressive cleaning agents, being especially suited to withstand steam-in-place (SIP) and clean-in-place (CIP) procedures within pipe work and vessels. G75S is also suitable for other critical applications such as Water-For-Injection (WFI) systems. Available in the hardnesses of 72 and 80 °IRHD.

Perlast® G80A, G60A, G70A, G90A

This black general purpose perfluoroelastomer compound with excellent chemical resistance is a very popular all rounder material. It is particularly suitable for various industries applications with an optimal cost-ratio performance for the users. Exceptionally high chemical resistance and excellent steam resistance and mechanical properties. Extremely low outgassing properties. Available in the hardnesses of 60, 70, 80 and 90 °IRHD
