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).

Can TMTD be used as a secondary accelerator?

TMTD can be used as a single accelerator, as a secondary accelerator or as a sulfur donor in most sulfur-cured elastomers. TMTD is scorchy and gives fast cure rates. In sulfurless and EV cure systems TMTD produces an excellent vulcanization plateau with good heat aging and compression set resistance.

What is MBT accelerator?

MBT Fast, non-staining accelerator for both dry rubber and latex applications. Low temperature curing can be achieved by the use of TMTD, TETD or DPG as secondary accelerators. MBT confers excellent ageing characteristics to vulcanizates. Gives flat, moderately fast cures in natural and synthetic rubber.

What is a rubber accelerator?

The range of rubber accelerators we have are produced by leading producers of rubber chemicals. They combine state-of-the-art technology with world-class manufacturing. Our range of products: CBS is a primarily amine-based accelerator giving good scorch safety, a fast cure rate and good modulus development in a variety of general purpose polymers.

How do you break down dimacit TMTD?

With sulphur in conjunction with zinc oxide and fatty acid as activators (0.1 – 1% TMTD on the weight of the gum), In conjunction with accelerators such as mercaptobenzothiazole (0.25 – 0.5 TMTD on the weight of the gum). Inorganic acids break down Dimacit TMTD into carbon disulfide and hydrogen sulphide.

What is ZMBT used for?

ZMBT finds its main application in latex where it is used as a primary accelerator in combination with ZDMC or ZDEC. Latex films cured with ZMBT have a markedly higher modulus. Furthermore a better compression set resistance in latex foam can be achieved, without increasing the cure time.
