Physical Properties : This item,the surface is very smooth,high structure.Among soft carbon black,its strength-adding power is the best.
Usage : Its used in tyre,side tyre,inner tyre and compressed rubber stuff.
Function : This item applies to natural rubber and synthesi syntheticalrubberItiseasy to disperse,it can strong strengthen rubber stuff.Fast extruding,small swelling mouth,the surface is smooth. Vulcanizate can stand high heat and heat conduction is fine, elasticity and rebounding are excellent.When used in butyl inside tyre,it¡¯s better to use together with N660.

Activated carbon is defined as an amorphous carbon subjected to thermal treatment with oxidizing gases, vapors or a mixture of both (steam) to increase its adsorptive properties.
We can supply activated carbon for different uses in different mesh sizes, depending on the application and customer requirement:
4 x 8 / 6 x 12 / 8 x 30 / 12 x 40 / 30 x 70 / 70 x 325 or powder.
Applications:
* Water treatment
* Gold processing
* Waste water
* Food & beverage
* Air purification
* Agriculture.
