It is a very widely used and inexpensive
non-staining , non discolor ing
antioxidant for white / colored or
transparent rubber products based on
NR, IR, SBR, BR, NBR, CR, etc. It also
finds applications as a stabilizer for
synthetic rubbers and plastics such as
Polypropylene, Polyethylene, high
impact polystyrene, adhesives, oils and
plasticizers. It disperses very easily in dry
rubber compounds and does not bloom
or affect the color, odor and
transparency of the rubber product.

It offers good oxidation, heat and ozone
resistance as well as flex fatigue
resistance to transparent / white /
colored rubber vulcanizates and exhibits
good 'Color fastness' characteristics. It
is a suitable antioxidant for normal as
well as heat sensitized NR latex based compounds and its performance in
NR latex based vulcanizates is similar to
that of NR dry rubber based
vulcanizates. The combination of
Pentoflex – SP (E) and antioxidant
Pentoflex – TDQ offer synergistic effect
to improve the heat ageing resistance of
rubber vulcanizates at lower cost but
with only slight discoloration.

It is a very widely used and inexpensive
non - staining , non discoloring
antioxidant for white / colored or
transparent rubber products based on
NR, IR, SBR, BR, NBR, CR, etc. It also
finds applications as a stabilizer for
synthetic rubbers and plastics such as
Polypropylene, Polyethylene, high

Pentonox - TDQ
Antioxidants
Light brown to brown Granules/Powder
80 - 950C
0.5 - 1.5
It is an inexpensive and highly potent
staining type antioxidant most widely
used in the rubber com-pounds based
on NR, IR, SBR, BR, NBR and other diene rubber except CR
(polychloroprene). It offers excellent
long term protection to rubber
vulcanizates against oxidative ageing at
ambient as well as elevated
temperatures. It offers cost advantage
since only small dosage is sufficient to
obtain desired long term protection
against heat and oxidative ageing as well
as reversion resistance during over cure.
Pentonox - MBI
Antioxidant
Off white to White Powder
295 - 3000C
0.5 - 1.5
It is an usually non-staining antioxidant
for light-colored and white rubber
compounds and also used as a synergist
for other antioxidants. It provides the
vulcanizates with some protection
against copper and manganese
poisoning (rubber poisons). It gives
better results in combination with
dithiocarbamate and thiuram
accelerators than in combination with
other accelerators.
Pentonox - ZMBI
Antioxidant
Off white to White Powder
3000C Min.
0.5 - 1.5
It works as a non-staining secondary
antioxidant application for NR, CR, SBR,
NBR and Latex etc. It has the same effect
with 2- mercaptobenzimidazole (MB)
which can decompose peroxide. It is
better than MB in properties such as
reducing the instability of latex.
Pentonox - 6PPD
Antioxidant
Black/Brown Beads
45-500C
0.5 - 4.0
It is the most suitable PPD antidegradant
for NR, NR-BR blend, SBR, SBR-BR
blend, NBR, IR, IIR and polychloroprene
based compounds. It offers excellent
resistance to rubber vulcaizates against
degradative forces such as ozone (static
as well as dynamic), flexcracking and
fatigue, oxidative heat ageing, metal-ion
catalyzed oxidative ageing, UV light and
weathering. It beads are easy to handle
on all types of weighing systems and
quickly disperse in rubber compounds
even at lower processing temperatures.
