Rubber Accelerator TBSI

Product Name: Accelerator TBSI

Chemical Structure:

Chemical Name: N-t-butyl-2-benzothiazole sulfenimide

CAS No.: 3741-80-8

Function: The rubber added with TBSI can obtain good soorch safety and lower vulcanization rate, and show good curing reversion resistance, high modulus and lower heat generation.

·TBSI is an important sulfinylimide vulcanization accelerator, which can prolong the scorch time and has good vulcanization performance;

·TBSI will not generate carcinogenic nitrosamines in application, and can replace NOBS, TBBS and DCBS;

·TBSI can improve the anti-reversion and air aging properties of natural rubber, especially under high temperature vulcanization and over-vulcanization conditions;

·TBSI can improve the adhesion properties between rubber and copper plated steel wire.

TBSI can be applied to tire and rubber products, especially the tire steel wire adhesive compound and thick rubber products with high vulcanization performance requirements

Woven bags or paper-plastic composite bags lined with plastic bags.

Net weight: 25kg/ bag

Other packaging forms can be adopted according to customer requirements.

In original closed containers under cool and dry conditions max.

Validity: 2 year.

During transportation, it should be rainproof and sun-proof. When handling, it should be unloaded lightly to prevent collision.

1. What are the key advantages of TBSI compared with traditional accelerators? 

TBSI does not produce carcinogenic nitrosamines during usage. It can replace NOBS, TBBS and DCBS. It extends scorch time, improves anti-reversion and air aging resistance of natural rubber, and enhances adhesion between rubber and copper-plated steel wire.

2. What are the main applications of TBSI? 

It is widely used in tires and rubber goods. It is especially suitable for tire steel wire adhesive compounds and thick rubber products requiring high vulcanization performance.

3. What should we pay attention to during transportation and storage? 

Keep away from rain and direct sunlight in transit. Handle gently to avoid collision. Store in cool, dry place with tightly sealed original packaging.
