Description TBSI can replace NOBS which is carcinogenic and does not generates the nitrosamines as
primary amine-based accelerator . The rubber added with TBSI can obtain good
scorch safety and lower vulcanization rate, and show good curing reversion resistance,
high modulus and lower heat generation, which optimizes adhesion between rubber and
brass coated steel cord. Its physical properties and dynamic properties of cured rubber
are similar with NOBS and DCBS cured rubber. It can also replace the blend of primary
amine accelerator TBBS or CBS and scorch retarder CTP and be used alone, which makes
it ideal for thick articles requiring a balanced cure and provides improved reversion
resistance both during extended cure times at elevated temperatures and during product
Dosage: NR: 0.5 – 1.5 phr IR: 0.5 – 1.5 phr SBR: 0.5 – 1.5 phr
NBR: 0.5 – 1.5 phr HNBR: 0.5 – 1.5 phr
Applications : This product will not generate the carcinogenic substance- nitrosamines which be
known more secure from NOBS, DIBS and DCBS under the same operation temperature.
It can be used in NR, SBR, Butadiene rubber and IR. Especially apply to the furnace
black sizing material with strong acid, showing the much better activity than CBS and
Storage : The product should be stored in the dry and cooling place with good ventilation,avoiding
exposure of the packaged product to direct sunlight.
Packing : In 25kg paper bags with plastic inner.
