Key Features

Polymax GP550 is expertly Made from expanded natural graphite, boasting an impressive purity level of over 99%. This high-quality material is reinforced with a stainless steel foil insert (AISI 316; 0.05 mm), providing exceptional mechanical strength and enhanced durability. As a result, Polymax GP550 is ideal for a wide range of industrial applications, ensuring reliable performance even in the most demanding environments.

This innovative material has received BAM (oxygen) approval, underscoring its safety and reliability in oxygen-enriched settings. Such certifications guarantee that Polymax GP550 adheres to stringent industry standards, making it a trustworthy choice for various operational needs.

Polymax GP550 features low total sulfur and leachable chloride and fluoride contents (20 ppm each), alongside less than 1% ash content, highlighting its remarkable purity. The product also exhibits a compressibility rate of 42% and a recovery rate of 15%, ensuring excellent sealing capabilities and durability for long-term usage.

With substantial tensile strength, Polymax GP550 withstands residual stress of up to 49 MPa even after continuous exposure to high temperatures. This ensures that the material remains stable and reliable, contributing to efficient operations and reduced maintenance costs.

Additionally, Polymax GP550 maintains a specific leak rate of only 0.05 mg/(s·m), showcasing its exceptional compression and creep relaxation properties. This reliability is crucial for applications where performance under high stress and temperature variations is paramount.

Applications

Designed to excel in extreme environments, Polymax GP550 operates effectively 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 outstanding choice for high-stress applications across various industries.

Polymax GP550 is particularly suitable for the chemical and petrochemical industries, where its high-performance characteristics ensure safety and efficiency. Other applications include oil and gas production, power generation, and specialized manufacturing processes, making this product an essential component for any industrial operation that demands reliability and durability.
