vulcanization accelerators - lusida rubber.vulcanization of rubbers by sulfur alone is an extremely slow and inefficient process. the chemical reaction between sulfur and the rubber hydrocarbon occurs mainly ac (doublet the c = bonds ) and each crosslink requires 40 to 55 sulphur atoms (in the absence of accelerator). the process takes around 6 hours at 140°c

china rubber accelerator manufacturers low price rubber,the rubber accelerator is an after-effect accelerator for natural rubber, butadiene rubber, isoprene rubber, styrene-butadiene rubber and reclaimed rubber. it is usually used in the manufacture of cables, tapes, rubber shoes, inner tubes, bright colors, etc., especially for alkalis.
- What vulcanizing agent is used in rubber?
- Elemental sulfur is the predominant vulcanizing agent for general-purpose rubbers. It is used in combination with one or more accelerators and an activator system comprising zinc oxide and a fatty acid (normally stearic acid). The most popular accelerators are delayed-action sulfenamides, thiazoles, thiuram sulfides, dithocarbamates and guanidines.
- Which thiuram accelerator is best for vulcanization?
- ETU and thiurams: Thiuram accelerators, such as TMTD (Tetramethylthiuram Disulfide) and TMTM (Tetramethylthiuram Monosulfide), when combined with ETU, can enhance the vulcanization process and improve aging resistance.
- Which elastomers can be vulcanized?
- Certain elastomers such as chloroprene can be vulcanized by the action of metal oxides such as zinc oxide as well as sulfur. As a result, several of the same accelerators that are used with sulfur vulcanization systems can be used with zinc oxide/neoprene systems. Because there are so many, accelerators are generally classified by chemical family.
- Why are accelerators used in vulcanizing elastomers?
- Accelerators are added in small amounts to speed up the curing of adhesives by reducing the cure time and temperature of elastomers, particularly latex systems. The selection of an accelerator will depend on the specific vulcanizing system and curing properties.
- What determines vulcanization rate?
- The accelerator determines the rate of vulcanization, whereas the accelerator to sulfur ratio dictates the efficiency of vulcanization and, in turn, the thermal stability of the resulting vulcanizate. Certain elastomers such as chloroprene can be vulcanized by the action of metal oxides such as zinc oxide as well as sulfur.
- How do I select a vulcanizing accelerator?
- The selection of an accelerator will depend on the specific vulcanizing system and curing properties. Explore the classification of accelerators, the checklist to select the right accelerator based on the specific vulcanizing systems and curing properties.
