Rubber Accelerator (Tbsi)

We are among the distinguished names inside the enterprise in offering a huge range of Rubber Accelerator (TBSI) to our valued customers.

Description : TBSI is a primary amine-based accelerator which does not generates the nitrosamines and it can replace NOBS which is carcinogenic. 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 service life.

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 NOBS. 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.
