Refractory blanket (mat) FIREMASTER 607 BLANKET ALU 40

Refractory blanket (mat) FIREMASTER 607 BLANKET ALU 40FireMaster 607 TM ALU 40 Blanket is a flexible resilient product based on FireMaster 607 alkaline earth silicate blanket which incorporates an integral aluminium foil vapour barrier and is able to provide effective fire protection in standard, hydrocarbon and jet fire applications. FireMaster ALU 40 Blanket has all the excellent handling and fire peroformance features of standard FireMaster Blanket whilst offering the convenience of an integral vapour barrier. The aluminium foil is attached with mineral glue and therefore FireMaster ALU 40 Blanket is a non-combustible product. ALU 40 blanket can be based on either the standard or water repellent grades of FireMaster Blanket.

Refractory fibre blankets.

 Health aspects summary:

FireMaster 607 was designed for enhanced solubility in lung tissues. Rats have been exposed 6 hours a day, 5 days a week during 2 years at an average concentration of 200 F/ml (about 200 to 300 times higher than the concentration found in production plants) without showing any significant increase in lung tumours or fibrosis.
