P84® NT Polyimide Powder
Polyimide powder P84®NT unites the outstanding properties of polyimide, such as high temperature stability up to 350°C, chemical resistance, high mechanical strength, a low friction coefficient and minimal abrasion.
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.
Several types of polyimide powders are available to meet your requirements.
Pure polyimde or customized compounds? Compounds with functional fillers like PTFE, graphite, molybdenum sulfide, reinforcement with carbon or glass fibers can be produced upon request or choose from our standard portfolio.
Easy handling with free flowing properties and limited dust or small primary particles? From fine powder of 1-10µm to granules up to 3mm.
Hot or very hot? Two types of polymer modifications to meet even outstanding demands on temperature stability.
Big semifinished parts or a high number of small accurate parts? We distribute types for Hot compression molding as well as powder for direct forming.
Hot compression molding
Production of big semi-finished parts with best mechanical properties Powder is placed into a mold and sintered under a pressure of 400 kg/cm2 at about 360°C for 3 h.
Manufacturing of high quantities of small accurate parts. Small „green“ parts are produced in a press at ambient temperature and a pressure of about 4000 kg/cm2 within cycle times of a couple of seconds. The „green“ parts are then sintered in an oven without pressure.
