XPE foam, with the addition of offering flame retardation, is durable, long-lasting. It is formulated to absorb significant energy and offers excellent creep resistance under high static stress.
For commercial projects and use , fire retardant foam sheets (XPE foams sheets) have developed two fire retardant foams that is suitable for the majority of applications.
•Relatively unharmed by environmental factors
•Absorb shock and insulate noise
1. BS 476 Part 6 test indicates the performance of a material in the early stages of a fire and the test result is a Fire Propagation Index which is dependent on the ignition characteristics, the amount and rate of heat release and the ability of a material to accelerate fire growth. The lower the Index then the better the resistance of a material to fire growth.
Size of sample: 225mm*225mm
2. BS 476 Part 7 test measures the lateral spread of flame along the surface of the specimen in the vertical position. The classification system is based on the rate and extent of flame spread. The levels of irradiance are specified in the Standard, e.g. 32.5 kW/m2 at 75 mm measured along the sample which is placed at right angles to the radiant heat source.
Size of sample: 885mm*267mm
V2 burning stops within 30 seconds on a vertical specimen; drips of flaming particles are
V1: burning stops within 30 seconds on a vertical specimen; no drips allowed.
V0: burning stops within 10 seconds on a vertical specimen; no drips allowed
Materials classified HF-1 and HF-2 require self extinguishing < 2 secs and after-glow < 30 secs. HF-1 also requires that a cotton wool indicator placed under the test sample is not ignited by burning drips.
FMVSS 302 test is manufactured according to the Federal Motor Vehicle Safety Standard No. 302.
Size of sample: 100mm*356mm
