Description
Vulcanizing agent RPS***0
- Product Performance
Vulcanizing agent RPS***0,whose chemical
name is alkyl phenol disulfide,with brand name of VTB***0 or
V5(Vultac 5). The appearance of the product is brown resin-like
powder or solid,with combined sulur content of about *8%.The higher
the sulfur content,the resin softening point of the vulcanzing
agent is higher and its resin density is also higher,In general
case,its relative density of resin is 1.**1.4 and temperatureof
softening point is ****5
℃.
2.Application
Vulcanizing agent RPS***0 has specially functions when it used as
vucanizing agent for dienes rubber,especially for chlorinated butyl
rubber.since the product includes combined sulfur of *8%,in the
half effective and effective vulcanizing formulasystem,it
Thus totally replaces sulphur,monpholine(DTDM),N,N\'-Caprolactam
disulfide(DTDC).The product will release active sulfur after being
heated,generate vulcanization,while vulcanized rubber will not make
its inside aids to be migrated out to surface and elongation,as
tensile stress.Therefore,the manufacture articles which be
vulcanized by this vulcanizing agent will have superior resist heat
performance and aging resistance performance due to heat and
oxidation, and during the vulcanzing process,
does not form nitrosamine gas which can cause cancer.
3. USAGE
:
The product is a vulcanizing agent specially used for all-steel and
half-steel radial tire,and be cable to improve activity of
chlorinated butyl rubber and make it to be vulcanized
simultaneously and evently,increasing vulcanizing efficiency and
reducing defective rate of manufacture articles.In addition,the
produce can use as viscosity increaser for styrene-butadiene
rubber/acrylonitrile-butadiene rubber to increase operation
performance of styrene-butadiene rubber/acrylonitrile-butadiene
rubber and improve processing performance of mixed rubber.
The product mainly use for air-tight layer
rubber,tire(especiallyfor white tire side),tire surface
brbber,triangle rubber and buffer layer rubber for tire,secondly
also for conveyer belt,high pressure rubber pipe,high speed rubber
roller roller and seal gasket etc.
2. Usage
The product can be directly put into rubber material for use and
its additive amount is 0.**5.0 fraction.
