Mouldable Refractory

►Description:
Made from refractory aggregate,powder,binder and admixture.It has good work performance and plasticity. According to America ASTM, mouldable refractory’s plasticity index is more than 15%,castable refractory’s plasticity index is less than 15%.In China, mouldable refractory’s plasticity index is between 15%-40%.

►Features:
1.Excellent fluidity and plasticity, high refractoriness,
2.Good performance to thermal shock, anti-stripping,corrosion and abrasion resistance
3.Good volume stability, good associative property, low water absorption,
4.No need for any chemical additives, convenient installation to reach high
efficiency.

►Technical parameters:
