What is accelerator tbztd?

Accelerator TBzTD has been developed to replace thiurams such as TMTD in cases where the presence of harmful nitrosoamines is of concern. The dibenzylnitrosoamine is not carcinogenic, according to published literature. TBzTD is a fast curing primary or secondary accelerator and sulfur donor in NR, SBR and NBR applications.

Is nurchem tbztd-70 a good thiuram accelerator?

NURCHEM TBzTD-70 is a fast primary thiuram accelerator for NR, IR, BR,SBR and NBR. It used as a secondary accelerator too. In NR, in association with CBS, it is better in reversion and heat build up than TMTD and it has a longer scorch time.

Is tbztd carcinogenic?

TBBS may give equal modulus to CBS or MBS when used at a 10% lower level. TBzTD was developed to replace thiurams such as TMTD where the presence of nitrosamines is of concern. The dibenzylnitrosamine is not carcinogenic according to published literature. TBzTD is a fast curing primary or secondary accelerator in NR, SBR and NBR applications.

Is tbztd better than TMTD?

TBzTD is a fast curing primary or secondary accelerator and sulfur donor in NR, SBR and NBR applications. It is safer processing than TMTD and thus does not provide the curing activity (i.e. state-of-cure is lower and rate-of-cure is slower) of TMTD. Modest changes to the curing package (higher levels of elemental sulfur) can overcome this.

What is WESTCO™ TBzTD?

WESTCO™ TBzTD is a fast curing primary or secondary accelerator for NR, SBR, and NBR with long scorch times and low to nil nitrosamine generation during vulcanization. Packaging: 25 Kg Bags. Technical Product Sheets and SDS sheets are available for this 0.5% Max. accelerator.

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.
