Direction for use of Kaou AC-NS 75 Rubber Accelerating Agent

Chemical composition:
N-tert-butyl group-2-benzothiazole sulfamide (it is a kind of general-purpose pre-dispersing particle used for rubber industry, that has been made moisture-proof and electrostatic-prevent treatment)
Appearance:
yellow column particle
Quality index:

decrement when heating: ≤1.0%

Function:

   1. As a kind of retarding accelerator, the product is widely used for rubber industry, such as natural rubber, butadiene rubber, isoprene rubber and styrene-butadiene rubber as well as nitrilo butadiene rubber etc.
   2. The product possesses fine dispersing performance used in various kinds of sizing materials as a pre-dispersing matter, which keeps sizing material from scorching in a safe operative temperature.
   3. The product has a high vulcanized cross-linking property and wide vulcanized flat area, so the vulcanized size is of excellent physical and mechanical and anti-aging properties.
   4. In order to obtain the better retarding effect, the product can be used together with PVI (CTP).
   5. The product especially suits to be used for carbon black sizing material melted in oil furnace in which comparatively high alkali contains.
   6. It is a kind of particle product, so it is easy to be correctly measured, and it is also a dust-free product for bettering production conditions according to the requirements for materials' safety and environmental protection.

Use level:

  0.6~2.5 phr is generally used in composition.
