Product DescriptionSodium Formaldehyde Sulfoxylate/? RongaliteSodium Hydrosulfite Formaldehyde, commercially known as Rongalite, is a high-performance reducing agent widely recognized for its exceptional decolorizing and bleaching properties in industrial applications. This white crystalline powder or lump-form chemical, serves as a critical component in sectors such as textile manufacturing, synthetic rubber production, and organic synthesis. Its strong reductive capacity allows it to efficiently break down dyes, remove colorants, and facilitate complex chemical reactions where precise reduction is required.In the textile industry, Rongalite is indispensable for discharge printing, a technique that creates intricate patterns by selectively removing dyes from fabrics. It enables the production of sharp, high-contrast designs on materials like cotton, hemp, and artificial silk, while also being employed in stripping outdated dyes and bleaching textiles to achieve desired whiteness. Beyond textiles, Rongalite plays a key role in polymer chemistry, where it acts as a terminating agent in the synthesis of styrene-butadiene rubber (SBR) and neoprene, ensuring controlled polymerization and optimized product quality. Additionally, it serves as a mild reducing agent in specialized organic reactions, contributing to the synthesis of fine chemicals and pharmaceuticals.Technical specificationParameterRongalite PowderRongalite BlockAppearanceWhite fine crystalline powder, free-flowingWhite lumps or large crystalline particles, dense structureSolubility (in water)Freely soluble, fast dissolution rateFreely soluble, slow dissolution rate, requires stirring or crushingBulk DensityLow (lighter mass per unit volume)High (heavier mass per unit volume)pH(2%Water Solution )≥ 9.80≥ 9.80ApplicationsThe Premier Discharge Agent for TextilesAs the premier discharge agent for textiles, it expertly removes ground colors to create precise, vibrant patterns on dyed fabrics.Discharge PrintingVat Dye PrintingStripping & BleachingUsed as a discharging agent to destroy ground colors, producing sharp, fine white or light-colored patterns on dyed fabrics.Essential for developing vat dyes in printing processes, crucial for manufacturing high-quality printed fabrics.Effectively used for stripping dyes and bleaching textiles like cotton, hemp, and artificial silk.A Vital Agent in Polymer & Chemical SynthesisAs a vital reducing agent and polymerization terminator, Rongalite ensures controlled molecular structure and optimized quality in synthetic rubber and organic synthesis processes.Synthetic RubberOrganic SynthesisPolymer IndustryActs as a polymerization terminator and reducing agent in the production of styrene-butadiene rubber (SBR), neoprene, and other synthetic rubbers.Serves as a mild and selective reducing agent in various organic synthesis reactions.Used in some polymer production processes as a redox initiator component.Packaging and StorageRongalite Powder25 kg/bag: Composite woven bag with polyethylene inner liner, double-tied mouth for sealing.50 kg/drum: Sealed HDPE plastic drum with moisture-proof bag inside; lid must be tightly closed for airtightness.Rongalite Block50 kg/drum: Sealed HDPE plastic drum; blocks are neatly stacked inside; lid must be tightly closed to prevent moisture absorption.Store in a cool, dry, well-ventilated dedicated warehouse away from direct sunlight.Temperature should be ≤30°C, relative humidity ≤75%.Company ProfileShenyang Xingzhenghe Chemical Co., Ltd.Founded in 2009, Shenyang Xingzhenghe Chemical Co., Ltd. has grown into a nationally recognized high-tech enterprise specializing in the research, development, and production of premium fine chemicals.
