The products sold by ECFIA's members can be described under several headings. It is convenient to use the following descriptions:
Major Product Forms
- Bulk/Wool: The cotton wool-like material collected after fiberization - is sold as feedstock to other processes or for some minor uses.
- Blanket: A mat of wool is converted to a blanket by "needling". Pushing barbed needles into the mat and withdrawing them produces a coherent blanket. Blanket can be stacked or folded and compressed to produce modules.
- Modules: Retangular blocks ready for installation, for example, along furnace walls. Some modules have more complicated structures.
- Board: Rigid composite board containing a variety of organic and/or inorganic fillers and binders.
- Paper and Felt: Flexible composite often containing latex as a binder.
- Vacuum-Formed Shapes: Articles sometimes with complex shapes produced from wool mixed with fillers and binders in an aqueous suspension. They are then drawn into forms or moulds by vacuum where most of the water is removed. After further drying and finishing they can be supplied ready for installation with minimal further processing.
Other Product Forms
- Cement and Mastics: Sold as mixes or as mastics ready for installation.
- Textiles: Cloths, threads, ropes and yarns. A small proportion of HTIWs is converted into these forms for specialized applications.
