Reducing Agents Brüggemann

Reducing Agents

Since 1926, Brügge­­mann has success­­fully manu­­fac­tured and sold Brug­golite® sulfur based redu­­cing agents. Based on Sodium Form­al­de­hyde Sulfoxylate, the very first indus­trial chem­ical from Brügge­­mann, our devel­op­­ment expertise has expanded the applic­a­­tion areas where these products enable our customers to improve their mater­­ials.

Brügge­­mann is the first company to offer a sulfur-based form­al­de­hyde free redu­­cing agent, Brug­golite® FF6 M.  Our unique R&D activ­ities continue to develop new, envir­on­­ment­ally friendly grades of redu­­cing agents that provide addi­­tional bene­fits.  In addi­­tion to Brug­golite® grades in solid form, we also produce redu­­cing agents in stable liquid form for customers that want to avoid the hand­ling of solids.             

Our water soluble redu­­cing agents are supplied glob­ally to improve emul­­sion poly­­mers. New regu­latory demands for VOC/Form­al­de­hyde reduc­­tion in coat­ings and adhes­ives are achiev­­able with our advanced redu­­cing agents, enabling water­­borne poly­­mers to replace solvent based mater­­ials in many areas. Other typical indus­trial uses include textile, paper, and mineral bleaching.

Conven­tional Redu­cing Agents

Since 1926, Brügge­­mann has continu­ously manu­­fac­tured Sodium Form­al­de­hyde Sulfoxylate (SFS) in high volumes at our dedic­ated produc­­tion facil­ities in Heil­bronn, Germany.

Our histor­ical rela­­tion­­ship with customers has enabled us to optimize this indus­trial chem­ical for numerous applic­a­­tions with our high quality, low impurity products. We offer an entire port­­folio of SFS based redu­­cing agents, typic­ally used for emul­­sion poly­­mer­­­iz­a­­tion, mineral bleaching, and discharge printing.

Brug­golite® E01

Brug­golite® E01 (SFS) redu­­cing agent is avail­­able as fast dissolving powder with excel­lent water solu­bility or dust-free gran­ular solid form.  Suit­­able for use in acidic and alkaline envir­on­­ments.

Brug­golite® L40/L35/NO 5

Brug­golite® L40 (40%), L35 (35%), and NO 5 (40%) are aqueous solu­­tions of SFS supplied in poly­­ethylene drums, IBC totes, or tankers for customers that prefer not to dissolve solid SFS on site. Brug­golite® NO 5 offers reduced odor.

Brug­golite® NF

This unique SFS based redu­­cing agent in powder form is used to stabilize solu­­tions and prepar­a­­tions in the phar­ma­ceut­ical industry. Certi­fied to meet US phar­ma­­copeia require­­ments.
