Quality characteristics

Saint-Gobain's Meldin® semi-finished PI-s products are manufactured using compression molding (CM) or direct forming (DF) processes. The semi-finished parts produced using CM process have relatively higher mechanical properties due to higher level of PI-s powder compaction. In line with different requirements of the Industrial market, Saint-Gobain's Meldin® product family can provide:

• High temperature resistance intermittently up to 482°C and continuous use temperature up to 315°C

• Excellent chemical resistance

• Excellent dimensional stability at elevated temperatures


Semi finished Polyimide parts are machined to finished parts which are then used in various applications in the

a) automotive industry: thrust washer or piston rings in transmission and pumps replacing tradional metals

b) aero space industry: jet engine parts such as pads, bumpers, seals and bearings

c) industrial machinery: thermal insulators for hot runner nozzles used for injectionn molding of thermoplastic products such as PET-preforms

d) electronic industry: semiconductor manufacturing process equipment with high purity, high resistance to solvents, oils and other chemicals while maintaining a high thermal stability and high electrical insulative properties. Meldin® 7001 grade can meet these extreme requirements and is applied in very broad applications.
