About Weserland
Weserland GmbH from Hanover has been developing and manufacturing chemical formulations for over 70 years and specializes in the production of aqueous dispersions and blends. Core competencies include vulcanization systems for latex foam and latex coatings, flame-retardant and antistatic compounds for carpet backing coatings, and cationically stabilized latexes based on HS-SBR, nitrile-butadiene and chloroprene rubber for the modification of bitumen emulsions. Further products include coatings and finishes based on aqueous polymer dispersions, functionalized with additives such as flame retardants, as well as supplementary auxiliaries such as foam stabilizers, wetting agents, thickeners and gelling agents. The service portfolio covers formulation development, laboratory services, process optimization, contract manufacturing including filling in the smallest quantities, hazardous materials handling, storage and logistics through to on-site product launch. Customer industries include mattress and latex foam manufacturing, the flooring and textile industries, aerospace, shipbuilding, rail, automotive, as well as bitumen and road construction. Products are manufactured and delivered throughout Europe from the Hanover site.
