Abstract:

The flame resistance properties of oyster shells powder extracted from the
Caspian sea in Iran composites were studied. (0%, 2.5%, 5%, 10%, 15%
and 20%) (Wt. /wt) of added oyster shells powder with the particular size
(≤ 250 μm) where composite with low density polyethylene and several
factor were studied like average of average time of burning(ATB), rate of
burning(RB), average extent of burning(AEB) and percentage of the time
of burning(PTB). The obtained results showed that the average time of
burning initiates strongly impacts with (5%), increasing weight preparation
to(147Sec). And then begins to decline their behavior when increasing
proportions weighted. While, the composite shows exception behavior at
(20 %).
