Feature:

  • DMF free,highly active adsorption. Adsorb up to 34% of its own weight.

  • Long shelf life when stored in airtight conditions.

  • Non-flammable. Insoluble in water and any solvents.

  • Non-poisonous and tasteless,chemical stability.

  • After absorbing, it also remains physically unchanged.
