FIRE STOP BLOCKS & STRIP

 Composition: Inert vitreous silicate mineral wool bonded with a thermosetting phenolic resin, which has been urea extended. Up to 0.5% of mineral oil.

 8. Physical & Chemical

Properties. Appearance – vitreous mineral wool supplied in the form of slabs and in sectional form. Melting point – above 600°C Solubility – insoluble iner and generally chemically inert.

 9. Stability & Reactivity. No special physical conditions need to be avoided. No restrictions regarding incompatible materials. Above 230°C, some binder degradation may occur for a short while, leading to the evolution of small quantities of carbon dioxide, carbon monoxide and other trace gases.

 10. Toxicological Effects.  IARC Classification category 2B (in 1987). Subsequent human epidemiological studies show no link between exposure to mineral wool and lung disease
