effect of zinc dithiocarbamates and thiazole-based
at finding some rubber accelerators based on zinc dithiocarbamates (zdcs) that are widely used in the preparation of technological vulcanizates, especially in latex goods and cable.
richon rubber accelerator cbs powder low cost,a medium fast primary accelerator suitable for nr, ir, sbr, nbr, hr and epdm. an outstanding delayed action accelerator. be top effective and safe when used at ordinary processing. temperatures, causing no scorches.
high performance environmentally safer accelerator for elastomers
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.
accelerator dpg wellt dpg,rubber accelerator dpg may be used as a secondary accelerator with thiazoles and sulfenamides in nr and sbr compounds. exhibits better storage stability compared to thiuram and dithiocarbamates but is not as active.
accelerator tdec
rubber accelerator tdec is an extremely effective dithiocarbamate accelerator for use with natural rubber, sbr, epdm, nbr and others. it is especially active as a butyl rubber accelerator. akrochem tdec is an oil treated powder and is approximately 96% active.

- What are the four types of rubber accelerators?
- These four classes of rubber accelerators are: DITHIOCARBAMATE: The dithiocarbamates are secondary accelerators that are used at low phr levels in a rubber compound to “tweak” the cure system to a desired rate of cure. Examples of dithiocarbamates include ZDBC, ZDMC, ZEPC, Z5MC,
- Are Dithiocarbamates and thiurams safe?
- The conventional accelerators, dithiocarbamates, thiurams, thiazoles and sulphenamides alone and in combination are highly effective and efficient in most dry rubber and latex applications. However increased health and environmental concerns have been expressed in recent years over the uses of, particularly, dithiocarbamates and thiurams.
- What is PTDC & dixp vulcanisation accelerator?
- 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.
- Is zinc dithiocarbamate a safe accelerator derived from safe amine?
- NAJIB ALAM, SWAPAN KUMAR MANDAL, SUBHAS CHANDRA DEBNATH∗ Several zinc dithiocarbamates (ZDCs) as accelerator derived from safe amine has been exclusively studied in the presence of thiazole-based accelerators to introduce safe dithiocarbamate in the vulcanization of natural rubber.
