Polyimide is one of the most hightech polymers. It can be used in temperatures up to 350° C. Polyimide products replace materials like metal and offers even better characteristics, due to its heat resistance, chemical neutrality and lower density. It is used in advanced industries such as aviation, automobile and industrial machinery. These hightech products may be friction-pads for breaks or seal-rings for aerospace applications.
In line with different requirements of the industrial market, Meldin® product family can provide: High temperature resistance; intermittently up to 482°C and continous use temperature up to 315°C, Wide chemical resistance, Dimensional stability at eleveated temperatures. Semi finished Polyimide parts are machined to finished parts which are then used in various applications.
Rods are available at a length of 965mm. The diameters start from 6.3mm and go up to 82.5mm
Polyimide can be applied in: automotive industry (thrust washer or piston rings in transmission and pumps replacing tradional metals), aero space industry (jet engine parts such as pads, bumpers, seals and bearings), industrial machinery (thermal insulators for hot runner nozzles used for injectionn molding of thermoplastic products such as PET-preforms), 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.
Sheets are available at 305 x305mm width and length and with minimum thickness of 1.6mm up to maximum thickness of 50,8mm
DIRECT FORMED PARTS
Finished or semi-finished parts directly formed from PI powder offer all the attributes of sintered PI. The advantage of direct formed parts is the lower costs as quantitiy is increasing. Due to almost zero percent waste during production it can be a more economic production method. Machined parts are widely used for medium to big series and high precision applications. a) automotive industry: racing engine fuel line / b) jet engine: vane bushing or locknut insert / c) Industrial machinery: plasma cutting torch as gas distributers or sealing components / d) Semicon equimpent: heater coil spacer / e) life sciences: rotor seal or pneumatic surgical tool vane
Our finished parts are available according to your needs. We supply tailor made finished products made of polyimide
Using sinter technology, polyimide powder can be manufactured into semi-finished products and components. Industrial applications profiting from this material’s effectiveness range from automotive industry and aerospace to industrial applications and office machines. Compounds with solid lubricants like graphite, molybdenum sulfide or PTFE can be used for tribologically demanding applications.
The range of products that can be produced from our polyimide (PI) is only limited by the processing machines. Polyimide powder can be processed by hot compression molding, direct forming, iso-staticn compression molding or it can be compounded with other materials as an additive. Polyimide powder is often compounded with PTFE to increase certain properties of the PTFE.
Dexnyl PI is available in 2 different particle sizes and specifications. Our Dexnyl PI Powder 100P_19 very suitable for compounding and compression molding application and our Dexnyl PI Poder 260_19 is very suitable for producing compression molded and direct formed parts.
