We purchase full range tapered rotomolded barrels from 50L to 5000L to match diversified raw material storage of our integrated chemical factory. The tapered design facilitates complete material pouring without leftover residue, seamless one-piece PE structure prevents leakage of granular and mild corrosive liquid raw materials.
