thiuram class includes accelerators such as tmtm, tmtd, tetd, tbztd and dptt. thiurams are ultra-fast accelerators for nr, sbr, br, nbr and other highly unsaturated rubbers and the most preferred primary accelerator for sulfur cured low-unsaturation content rubbers like butyl (iir) and epdm.
rubber additives zmbt accelerator for rubber price,rubber additives zmbt accelerator is a primary accelerator for nr, sr and their latices; used as a secondary accelerator in sulfur cured latex.
considerations when selecting vulcanization accelerators
when selecting a vulcanization accelerator, it's important to consider several factors to ensure optimal performance and quality of the rubber compound. alfa chemistry lists 12 key points for you.

classification of rubber vulcanizing accelerators rubber accelerator
because the rubber vulcanizing accelerator has a great influence on the vulcanized rubber characteristics, it is necessary to classify and identify the three popular types of rubber vulcanizing accelerators to avoid using the wrong accelerator during tire production and to ensure the tire quality.
accelerators for tires and rubber products,an accelerator is defined as the chemical added into a rubber compound to increase the speed of vulcanization and to permit vulcanization to proceed at lower temperature and with greater efficiency.
high performance environmentally safer accelerator for elastomers,ptdc and dixp are recently developed ultra fast environmentally safer vulcanisation accelerators. they have major applications in dry rubber compounding (nr, sbr, nbr and epdm) as primary or secondary accelerators, capable of replacing established thiurams or dithiocarbamates on a weight to weight basis and giving superior vulcanisate properties.
- 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.
- What is the role of accelerator in vulcanization?
- Accelerator also Decreases the Quantity of Sulphur necessary for vulcanization and thus improving 'aged' properties of the rubber vulcanizates. Accelerators are also classified as Primary and / or Secondary accelerators based on the role they play in a given compound.
- How is rubber vulcanized?
- Vulcanization of rubbers by sulfur alone is an extremely slow and inefficient process. The chemical reaction between sulfur and the Rubber Hydrocarbon occurs mainly at the C = C (double bonds) and each crosslink requires 40 to 55 sulphur atoms (in the absence of accelerator).
- 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.
