The new Alphawool bulk long-fibre product, which is manufactured at a dedicated facility in the UK, is available in two grades: Alphawool LA with a classification temperature of 1,500ºC and Alphawool HA which has a classification temperature of 1,600ºC.
It does not contain a binder and so emits no fumes or smell during first use. A high alumina content of between 96 and 97 percent, with low ‘shot’ content below one percent, creates a lightweight yet highly resilient product which is chemically and thermally stable, with low linear shrinkage, low thermal mass and strong insulating properties.
Alphawool is unclassified under the European CLP regulation (Directive 1272/2008) by virtue of its very low content of respirable fibres.
