Characteristics

Pure natural gas made,Highest purity and lowest sieve residue.Large particle size,low structure.

Good processability,used as filler,reducing the cost of rubber.Used in the manufacture of high-grade rubber seal products,unique filling and reinforcing. used in silicon /fluorine rubber.

Finished rubber products in good elasticity, good elongation, low heat build-up, low compression set, low hardness, better aging resistance and flexing resistance.
