classification of rubber accelerator zdec
the thiuram class comprises accelerators like tmtm, tmtd, tetd, tbztd, and dptt. thiurams are highly efficient accelerators used in the vulcanization of nr, sbr, br, nbr, and other highly unsaturated rubbers. they are particularly favored as primary
Rubber Additives tetd accelerator for best selling,cas# 97-77-8. Rubber Additives tetd is an accelerator suitable for most sulfur-cured elastomers. it acts as both an accelerator and a vulcanizing agent in low sulfur and sulfurless stocks. its low melting point provides excellent dispersion in soft compounds. it is used as a cure modifier for polychloroprene. Rubber Additives tetd provides better processing.

- What is TMTD used for?
- TMTD is widely used in rubber processing as an ultra accelerator for low-temperature cures, either alone or as an activator for other accelerators, chiefly the thiazoles. It can be used: In conjunction with accelerators such as mercaptobenzothiazole (0.25 – 0.5 TMTD on the weight of the gum).
- What is accelerator TMTD?
- Accelerator TMTD is also available in a pellet form and micro granules (MG) to reduce dusting. TMTD contains 13% available sulfur. Improved scorch resistance can be obtained in TMTD stocks by the use of the thiazole or sulfenamide accelerators as a primary accelerators. TMTD is an off-white to light gray in color.
- Does TMTD require sulfur?
- Sulfur is not required but is often used. It is widely used as a primary accelerator for curing systems requiring very low or no sulfur. TMTD is often used to activate thiazole or sulfenamide cure systems. Accelerator TMTD is also available in a pellet form and micro granules (MG) to reduce dusting. TMTD contains 13% available sulfur.
- What is a thiuram accelerator?
- The thiuram class comprises accelerators like TMTM, TMTD, TETD, TBzTD, and DPTT. Thiurams are highly efficient accelerators used in the vulcanization of NR, SBR, BR, NBR, and other highly unsaturated rubbers. They are particularly favored as primary accelerators for low-unsaturation rubbers like butyl (IIR) and EPDM, which undergo sulfur curing.
- Which thiuram accelerator has the best cure rate?
- The activity of various thiuram accelerators can be summarized as follows in terms of cure characteristics: Scorch Safety: TMTD exhibits the longest scorch safety, followed by TETD, and then TMTM. Cure Rate: TMTM, TETD, and TMTD all possess similar fast curing rates.
- Can thiurams be used as a secondary accelerator?
- They are particularly favored as primary accelerators for low-unsaturation rubbers like butyl (IIR) and EPDM, which undergo sulfur curing. In combination with thiazole/sulfenamide accelerators, thiurams are commonly used as secondary accelerators at levels of 0.05 – 0.4 phr.
