Perlast® FFKM is prized for its high temperature capabilities and outstanding low compression set, making it an ideal candidate for mechanical seal O-rings.
Perlast® G77X has been specifically developed to deliver optimal O-ring performance in mechanical seals used in rotating equipment.
Perlast® G77X is a class-leading FFKM for mechanical seals, offering:
High temperature capability
Low compression set
Chemical resistance
Mechanical strength
Key benefits of Perlast® G77X
By specifying Perlast® G77X as part of your sealing solution for mechanical seals, you can expect several key advantages in terms of performance and reliability.
Perlast® G77X’s industry-leading high temperature capability together with low compression set is a combination ideally suited to the unique challenges of mechanical seals. The extended seal life afforded by this material will significantly improve maintenance cycles, with an associated reduction in overall cost of ownership.
High temperature capability
Outstanding seal force retention
Extended maintenance intervals
Reduced cost of ownership
Perlast® G77X represents a process-enabling step change in high temperature capability, sealing up to 350°C (662°F) which outperforms competitor materials.
This innovative elastomer material also demonstrates an excellent response to temperature cycling effects, underpinning its durability and giving peace of mind for its operational reliability.
The low compression set performance of Perlast® G77X enables outstanding seal force retention properties, resulting in superior durability and extended seal life in comparison to similar materials.
The mechanical strength of Perlast® G77X, and its resistance to thermal extremes and aggressive chemical environments, is both increasing safety margins for operators and also extending maintenance intervals (or Mean Time Between Repair – MTBR).
Perlast® G77X is lowering the overall cost of ownership for mechanical seal operators, minimising equipment downtime with significant reductions in seal maintenance and repair.
Our specialist sealing engineers will work with you to develop a Perlast-based sealing solution which decreases the likelihood of unscheduled downtime events, and maximises the productivity and profitability of your operations.
