Slab-form Polymer-bound Thiuram Accelerator TT TMTD-80

Slab-form Polymer-bound Thiuram Accelerator TT TMTD-80

Tetramethylthiuram disulfide

C6H12N2S4

M.W.: 240.43

CAS: 137-26-8

EINECS: 205-286-2

PROPERTIES:
Actmix TMTD-80 can extremely accelerate curing rate of natural and synthetic rubber and has good scorching safety. It almost does`t affect degree of cross-linking but lower scorching rate and extend total curing time when thiols or sulfenamides is added in. Aldehyde- amines and guanidines alkaline accelerators can activate TMTD. It is a primary accelerator with sulfur, a secondary accelerator with thiazoles and a vulcanizer in sulfurless vulcanization. Sulfurless or low-sulfur vulcanization can provide excellent heat aging resistance properties for vulcanizates.

Compared to traditional TMTD powder, Actmix®TMTD-80PE F140 allows:

Dust free products with a complete filtration up to 100µm, no skin sensitization, health guard of operators.

Effective guarantee of activity of TMTD due to pre-dispersed masterbatch.

Tack free products at room temperature, convenience and accuracy on ingredients.

Lower Mooney viscosity at lower temperature (50℃), higher quality of dispersion.

Impurity free, blocked filter free of extrusive products, scrap rate reduction and higher productivity thanks to filtration.

Wider compatibility with other elastomers.
