Hydrogen peroxide 35 % (CAS 7722‑84‑1) supplied by Global Optimals is a clear aqueous solution with a concentration range of 35–50 % w/w and purity of ≥ 99.9 %. The product serves as a chlorine‑free bleaching agent in pulp and paper manufacturing, efficiently removing lignin, increasing brightness, and reducing the need for additional chemicals. Technical peroxide provides an oxidation potential of ≈ 1.2 V, which promotes fiber swelling and improves paper whiteness. Recommended storage temperature is 5‑25 °C, protected from direct sunlight and contact with aluminum or copper metals; under these conditions the solution remains stable for up to 12 months. It is packed in 200 L steel drums with an internal coating to prevent metal‑catalyzed decomposition. Each shipment includes complete documentation – TDS, SDS, and COA – complying with GOST and ISO standards. In typical pulp bleaching sequences, peroxide is introduced in the pre‑bleach stage where it reacts with residual xanthate, and again in the final stage together with sodium hydroxide to achieve deep delignification. The generated hydroxyl radicals attack aromatic lignin structures, breaking them into soluble fragments and enhancing fiber brightness. When dosed at 0.5‑1 % of dry pulp weight, peroxide yields a brightness gain of 10‑15 % while preserving fiber strength. It is compatible with alkaline (lime) and enzymatic bleaching streams, allowing seamless integration into existing lines without major equipment changes. Proper handling includes using rubber or polypropylene hoses, ensuring good ventilation, and wearing appropriate personal protective equipment. Correct dosing typically raises the tensile strength of the paper sheet by 8‑12 % due to stronger fiber bonding, and also improves surface smoothness, which is valuable for printing and packaging grades. The peroxide’s oxidative action reduces the load on wastewater treatment by minimizing chlorinated by‑products, supporting modern environmental regulations. In case of spills, dilute with abundant water and neutralize with a 5 % sodium hydroxide solution.

Big bags 1000 kg / Tankers
Store 35 % hydrogen peroxide in a cool, dry, well‑ventilated area away from direct sunlight and heat sources. Recommended storage temperature is between +5 °C and +25 °C; higher temperatures accelerate decomposition and oxygen release. Shelf life is typically 12–24 months provided the container remains intact. Use protective gloves, safety goggles and adequate ventilation during handling, and avoid contact with organic materials or catalytic metals. Packaging—usually high‑density polyethylene or stainless‑steel drums—must be tightly sealed and free of any dents or leaks.
