Recycling of gel foam rubber waste as filler in
natural rubber/styrene butadiene rubber (NR/
SBR) blends for mats production

G
el foam was used on a wide range in carpets backing
production to give the tuft strength and to make it
compact. The gel foamwaste consists of a blend fromNR/SBR
in addition to amounts of CaCO
3
. This waste was collected
and recycled to work as filler in mats production. It was dried
and grinded into particles with a size range from 45 to 75
microns and used as a replacement to parts of CaCO
3
filler
in different ratios. The mechanical properties of prepared
mats using recycled waste were studied and the surface was
scanned using SEM. It was found that replacing CaCO
3
by
waste rubber in ratios up to 5 and 7% has improved the
mechanical properties at 3% ammonium acetate gelling agent.
Moreover, it has provided better storage stability than CaCO
3
.
Reducing gelling agent to 2.5% has resulted in recycling high
amount of this waste; up to 25%.and up to 60% by reducing
the gelling agent to 2%. Reducing the ratio of the gelling agent
and recycling of such waste are very cost effective. In addition,
it helps in decreasing the acetic acid emission and enables the
final product to have a good appearance.
