YH**9 is used
successfully in the rubber industry as a dual functional
organic
poly sulfur
silane coupling agent.
YH**9 can be
used in the vulcanized rubber system with fillers such as
silica,
fiberglass,
talc powder, mica powder and clay as reinforcing agent. It can
improve the reinforcing
properties of fillers and rubber abrasive resistance properties.It
is suitable
to be used as
rubber additive**-vulcanizing agent and activator in polymers such
as
NR, IR, SBR,
BR, NBR and EPDM.
In the
process of vulcanization, the crosslinking rate of poly-sulfur
alkyl is the same
as
deoxidizing rate of sulfur, so it act to resist deoxidization of
vulcanization, and then
improve
dynamic bending properties such as heat build up and cracks
expansion .The
four sulfur
atoms can act as activator for
vulcanization.
In dynamic
and static conditions, It is used for producing these rubber
products: tire,
hose, rubber
roll, belting, cable, footwear and mechanical founding products. It
can
improve
abrasive resistance, cutting resistance and pressure resistance,
reduce
hysteresis
loss and hygroscopicity, improve mechanical and adhesive
properties, and
increase
thermal ageing performance, modulus and flex
life.
Add
sulfur-silane coupling agent in the industry of rubber tire, its
not only debase
the risk of
puncture as temperature too high running on the high speed road or
long
time, but
also reduce roll resistance of tire, then reduce the consume of
gasoline, the
emissions
quantity of COâ‚‚ as to accord the environmental protection of
carbon
reduction.
