Key Features

Polymax GP550, a premium sealing solution expertly Made from expanded natural graphite, boasting an impressive purity of over 99%. This innovative material is reinforced with a stainless steel foil insert (AISI 316; 0.05 mm), ensuring remarkable mechanical strength and outstanding durability. The Polymax GP550 is specifically engineered to excel in various demanding industrial applications.

Certified with BAM (oxygen) approval, the Polymax GP550 guarantees safety and reliability, particularly in oxygen-enriched environments. This certification highlights our commitment to meeting rigorous industry standards and compliance requirements, making it a trustworthy choice for professionals.

With exceptional physical properties, the Polymax GP550 demonstrates a 42% compressibility rate and a 15% recovery rate, facilitating tight sealing and long-term usage. Its robust tensile strength allows it to endure residual stress of up to 49 MPa, even after prolonged exposure to extreme temperatures. The material’s superior purity is further confirmed by its low total sulfur and leachable chloride and fluoride contents (20 ppm each), complemented by an ash content of less than 1%, which enhances its suitability for sensitive applications.

Additionally, the Polymax GP550 maintains a specific leak rate of only 0.05 mg/(s·m) and showcases impressive compression and creep relaxation properties, ensuring reliability and stability under high stress and temperature fluctuations.

Applications

The Polymax GP550 is designed to perform in extreme environments, capable of operating at temperatures ranging from -200°C (-328°F) to 550°C (1022°F) in oxidizing atmospheres, and up to 700°C (1292°F) in reducing or inert atmospheres. Its maximum pressure capacity of 100 bar (1450 psi) makes it an ideal choice for high-stress applications, particularly in the chemical, petrochemical, and energy industries.

This versatile sealing material is perfect for use in valves, pumps, and heat exchangers, ensuring optimal performance and longevity. Choose Polymax GP550 for exceptional sealing solutions that meet the highest standards of safety and efficiency in even the most challenging industrial settings.
