BNZ Marinite® is Discontinued.
AWMCO Has Your Replacement.

BNZ Materials has permanently discontinued the Marinite product line. All Marinite grades (A, C, I, M and P) are final, non-restocking inventory. When current stock is gone, it is gone. AWMCO holds some of the last remaining supply.

Two replacement paths are available depending on your grade and timeline. Super Firetemp® from Johns Manville is in stock now with monthly restocking, a direct conversion for most applications. Promat® products are sourced to order and offer EN-compliant, grade-matched alternatives with published thermal and structural data. AWMCO supplies both.
