Precision Polymer Engineering Perlast® G75B High Temperature Perfluoroelastomer

Subcategory: Fluoropolymer, TS; Elastomer, TS; Thermoset

Key Words: Rubbers

Material Notes:
Perlast® G75B offers a unique blend of excellent chemical resistance, temperature capabilities and mechanical properties, simultaneously extending the operating limits in all three aspects. 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.

Applications: Aerospace: Inter-stage seal assemblies (static O-rings). Chemical Processing: Pumps; Valves; Mechanical seals. Diesel: Cylinder bore liners (static O-rings); Exhaust valve seats. Semiconductor: Gas abatement systems (static); High vibration environments. Oil & Gas: High temperature down-hole environments; Electrical bulkhead feed-throughs.
