Fibre Formulation
Starting with the raw material of waste newsprint, Excel is able to processes the paper into its original fibrous state and formulate the fibreised material, so that it has the required structure and properties needed for its particular application. Much of this formulation is in the engineering of the fibre to meet the specific performance criteria for each of the very diverse application needs. Fibres can be created that vary from an almost powder-like appearance, for use in paints for example, to longer fibres with excellent weave characteristics, which are essential in road fibres or in sound insulation products.
Performance Enhancement
To accentuate any particular aspect of the processed fibre’s performance characteristics, the manufacturing facility is then able to introduce natural, inorganic and non-toxic additives to the fibre mix, which are dispersed evenly throughout the fibre. Typical performance enhancements may include, for example, improved resistance to fire (essential in house insulation), greater fluidity and dispersal (necessary for SMA road surface mixes) or the ability to absorb water more effectively (used in concrete repair).
Special grades of fibre can also be produced, by varying the feedstock raw material, to match very specific application criteria, such as a need for very high wet strength. Feedstock is also key in creating fibre products where colour is important, such as in ultra white fibre used to create special effects snow scenes for the film industry.
