Graficomp are composite material soaking special synthetic tissues with thermo-fixed resins. The physical and mechanical properties of all the Graficomp material are an excellent option to tribology material.
The Graficomp composites can be uses in bearings, wear plates, self-lubricating guides and other compounds, replacing bronze and graphite bronze.
This line can be used in industry of power generation, petroleum and gas, and naval industry.
It is a composite nano additive composed of an epoxy resin matrix reinforced with polyester fabric that forms the structural part of the system. The sliding layer consists of a 50% PTFE fabric and 50% Dacron, giving the product a low coefficient of friction. The epoxy resin that binds the entire assembly has low water absorption making this material ideal for applications submerged in water.
Applications: Bearing bearings, directional vane bearings, servo wear rings, locking bearings, vertical and horizontal segments of throttle rings, butterfly valve bushings, pivoting or lifting bridge plates.
