Understanding the Composition of a Nitrile (Buna-N) Rubber
Acrylonitrile Butadiene Rubber (NBR) or Nitrile rubber is one of the most popular compounds for automotive applications. It also is well known as Buna-N.This name came from one of the first base polymers patented in 1934, therefore people commonly use this name for all classes for Nitrile to this day.

- What is accelerator TBSI powder?
- Accelerator TBSI Powder is a primary amine-based accelerator which does not generates the nitrosamines and it can replace NOBS which is carcinogenic.
- What is TBSI powder?
- Contact us today! TBSI Powder is a non-carcinogenic accelerator that enhances scorch safety, reversion resistance, and adhesion to brass-coated steel cord in thick rubber.
- Why is TBSI used in radial tyres?
- It promotes adhesion of rubber to brass coated steel and is recommended for Radial Tyres. It gives better reversion resistance as compared to sulphenamide accelerators in diene rubbers. TBSI due to its sulphenimide structure has excellent storage stability in Hot and Humid Conditions.
- Why is TBSI used in diene rubbers?
- It gives better reversion resistance as compared to sulphenamide accelerators in diene rubbers. TBSI due to its sulphenimide structure has excellent storage stability in Hot and Humid Conditions. It is used at levels similar to those used with sulphenamide accelerators. Store in a cool and dry place.
- What is TBSI cured rubber?
- 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.
- What is a satisfactory delayed action accelerator?
- 0.5 max. 2.0 max. 0.5 max. A satisfactory delayed action accelerator is one that remains substantially inert during rubber compounding operation, but gives reasonable rate of cure when the temperature of the mixture is raised to effect vulcanization. QUREACC®TBSI is a delayed action primary amine based accelerator.
