Meldin® | A Family of High-Performance Solutions

Meldin® Polyimides

High-Performance Thermoset Materials

Meldin® polyimide materials are engineered for high-demand applications. These materials exhibit high dimensional stability and can be used in specialized applications where high thermal resistance and good mechanical properties at high temperatures are required. They retain their critical properties at continuous operating temperatures from cryogenic through 600°F and can be used intermittently up to +900°F. These lightweight materials can withstand harsh chemicals, high pressure, and extreme speeds, friction and wear.

Solutions include bearings, wear components, seals, piston rings, and thrust washers. They are also available in custom shapes, rods, sheets, and tubes. These materials are ideal for applications in many industries including aviation, industrial, semi-conductor, space, and life science.
