    What are rubber accelerators? Rubber accelerators are chemicals used to speed up the manufacturing process of rubber (vulcanisation). This process makes untreated natural rubber latex suitable for use in the manufacture of many rubber products. There are many types of rubber accelerators in use but those listed below cause most cases of rubber contact dermatitis:

  • rubber accelerators speed up rubber vulcanization

    Rubber Accelerators Speed Up Rubber Vulcanization

    Rubber accelerator CZ is used as medium-fast primary accelerator for natural rubber, isoprene rubber, styrene butadiene rubber and nitrile rubber. It is also used as the secondary accelerator together with other accelerators to adjust rubber vulcanization speed.

  • common vulcanization accelerators - crow

    Common Vulcanization Accelerators - CROW

    Vulcanization Accelerator. is a compound that increases the speed of vulcanization and that enables vulcanization to proceed at lower temperature and with greater efficiency. Vulcanization accelerators can be classified as primary and secondary accelerators. Important primary accelerators include thiazoles and sulfenamides.

    Vulcanization & Accelerators - Nocil Ltd

    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

  • ultra/secondary accelerators: accelerators and zdmc

    ULTRA/SECONDARY ACCELERATORS: accelerators and ZDMC

    selection of ultra/secondary accelerators in combination with a delayed action accelerator (e.g. sulfenamide) will allow sufficient scorch delay before the onset of vulcanization and high torque after the start of vulcanization. One must select ultra/secondary accelerators that work in a synergistic manner with other ingredients in a compound.

    Thiurams--Accelerator TMTD(TT)

    Scorchy and gives fast cure rates. Produces an excellent vulcanisation plateau with good heat aging and compression set resistance in sulphurless and EV cure systems Good color retention is obtained in non-black vulcanisation. A valuable secondary accelerator for EPDM.

  • effects of accelerators on the cure characteristics

    Effects of accelerators on the cure characteristics

    compounding additives and predictable vulcanisation properties [1]. In sulphur curing, two or more accelerators are used to accelerate the cure by providing a synergistic curing effect [4]. An accelerator with a slower cure serves as the primary accelerator, reacting with another faster type that serves as the secondary accelerator.

  • accelerant

    Accelerant

    Rubber vulcanization. Accelerators and activators break sulfur chains. Accelerated sulfur vulcanization systems require only 5-15 sulfur atoms per cross-link as compared to 40-45 S atoms/crosslink for a non-accelerated sulfur vulcanization. There are many accelerators available for the vulcanization of rubber.
