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.
