Rubber Accelerator Vulcanizing Agent

Description

Vulcanizing agent RPS***0

1. 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.
