Abstract:
Various flammability properties of a siloxane-containing
bisphenol-A polycarbonate sample, with the siloxane as
an additive or as a copolymer, were measured and
compared with those of a pure polycarbonate sample. The
results show that the peak heat release rate for the
siloxane-containing polycarbonate sample is
significantly reduced (less than half) compared to that
for the pure polycarbonate sample with two different
sizes of sample, 10cmx10cm and 40cmx40cm. However, the
ignition delay time for the siloxane-containing sample
is shorter than that for the pure polycarbonate sample.
Also, the flame spread rate under an external radiant
flux becomes faster for the siloxane-containing sample
than that for the pure polycarbonate sample. The
observed char behavior, such as char depth, physical
nature and apparent combustibility, and its impact on
flammability properties are discussed.
