Characteristics of new organic fireproof materials for nitrogen generator
The oxygen index of phenolic FRP can be more than 50, and the oxygen index of phenolic FRF with filler can even be more than 70. The oxygen index of other materials without flame retardants is: epoxy resin 1918, polyethylene 1718, polypropylene 1717, polyurethane 20.
The smoke index of phenolic FRP is 7, while that of polyurethane, PVC is 400 and polystyrene is 300. The smoke density of epoxy resin and polyurethane increases with the increase of combustion time, which exceeds 400 in 10 minutes, while that of phenolic FRP is less than 10.
