Filler ZPSp-90

High-magnesium filler ZPSp-90 is a refractory granular material based on magnesium oxide (MgO) with a mass fraction of at least 90%. The material is characterised by high fire resistance, excellent slag resistance and structural stability under prolonged exposure to high temperatures. Due to the predominance of the magnesia phase, the filler works effectively in alkaline and metallurgical environments. ZPSp-90 is widely used in the production of refractory concretes, ramming and casting mixes, as well as linings for thermal units operated under conditions of intense chemical and thermal exposure.
