-----------------------------------------------------------------3.Product Usage

1. For making dry batteries, acetylene black can improve conductivity, increase the discharge volume and extend the discharge time.

 

2. For battery plate including lead-acid battery, Lithium battery and lithium-ion battery.

 

3. Used for conductive and anti-static rubber, silicone rubber as well as plastic, it has the features of small specific gravity, good reinforcement, corrosion-resistant, good processability. The conductivity is easy to control.

 

4. Special tires and tire capsule. Acetylene black can work as reinforcing and heat conducting. The vulcanizate reinforced by it has got very high stretch intensity and hardness with good physical properties.

 

5. Used for electromagnetic insulation and gas dispersion electrode.
