esdonor® 5 is mixture of poly-tert-amylphenol disulfide (75wt%) and silica gel (25wt%)  which acts as a vulcanizing agent and antioxidant. It is a nitrosamine-free, sulfur donor, with high elastomer solubility. esdonor® 5 is a sulfur donor for natural and synthetic rubbers. It produce a high percentage of mono-sulfidic crosslinks that results in vulcanizates with superior aging characteristics. It can be used as either complete or partial replacements for sulfur and thiuram and dtdm sulfur donors in ev and semi-ev type cure systems. In tires it is used in the innerliner, chafer, bead apex, sidewalls, and tread. Industrial applications include noise damping blocks, motor mounts, dock fenders, elastic threads, automobile engine hoses, gaskets, belts, and other industrial rubber products that require good heat resistance. specifications: appearance: beige free flowinng powder sulfur content: 18.5-21.0 wt%   packaging: 20kg/bag   arkema vultac 5 vulcanizing agent equivalent

rostab® 323, for rosin resin, is the antioxidant which has double efficacies of both free radical termination and hydroperoxide decomposition. It means that, it has the double functions of both the primary antioxodant and the secondary antioxidant. It is the bleaching agent and the disproportionation catalyst for the rosin esters, tall oil rosins and the rosin ester obviously. It can act as rosin disproportionation catalyst to transform the unsaturated conjugated double bonds abietic-type acid which is susceptive to be oxidative into dehydroabietic acid which is stable.   1, rosin or rosin resins such as pentaerythritol rosin ester, maleic acid resins, glycerol rosin ester: adding 0.2-0.3% 323 and 2-3 gardner can be improved greatly.   2, disproportionation of rosin: it is an efficient catalyst for the disproportionation of rosin. It converts instable conjugated double bond in the rosin molecule into stable conjugated double bond with an aromatic ring structure, which means to convert the abietic acid into dehydroabietic acid. The dosage in the process is 0.1-0.3% and optimum amount is 0.2%.    3, anti-crystallization of rosin: rosin is a non-crystalline transparent solid, but it tends to crystallize. Crystallization of rosin causes a reduction in rosin's transparency and solubility, affecting its usage. Adding 0.2% 323 to the rosin and it can improve its anti-crystallization performance.   usage method                                                                     rostab 323 is a viscous liquid at room temperature. It is recommended to preheat the packing drum to 70-80 ºc to facilitate operations.   specifications: appearance: dark brown viscous liquid sulfur content: 9.4-10.6% chloride content:0.1% max   packing: 200kg/drum
