Raw material characteristics of MBT**5: |
Â
Use Characteristics
1. MBT**5 is most frequently used for NR, SBR, IIR and CR, used
independently or together with basic accelerators. It is a
semi-ultra, multi-ourpose accelerator with a long plateau effect.
It provides vulcanizates with good physical
properties.        Â
                            2.
In sulfur free compounds, MBT**5 acts as an anti-scorch agent, in
CR compounds as a
retarder.                                                                                         Â
3. MBT**5 is activated by basic accelerators as aldehyde amine and
guanidine etc., and by thiurams and dithiocarbamates. Activated
MBT**5 may scorch, however additional processing safety can be
obtained by the use of a retarder as
CTP**0.                     Â
          4. It
is non-discoloring and non-staining.
Â
Processing Advantages
The thermoplastic, excellent compatible EPDM/EVA binder which is combined with active dispersing promoters allows much more easy quickly incorporation and excellent dispersion in the rubber mixing. In this way, optimal activity of the effective MBT is assured.
Â
Dosage:
NR and SBR: primary: 1.0~2.0phr with 2.0~3.0phr S**0;
secondary: 0.5~1.0phr with 0.2~0.3phr TMTD and 1.5phr S
IIR:  0.5~1phr with 0.5~1.5phr TMTD**0
and 1~2phr sulfur.
Â
Applications:
Automotive and construction profile, tire treads, air hoses, conveyor belts, footwear and other technical articles.
