Lanxess: Broadest ever portfolio for PU production

With its most comprehensive ever product portfolio for the polyurethane industry Lanxess exhibited at Utech Europe. The portfolio encompasses not only additives like flame retardants, plasticizers, crosslinkers, catalysts and hydrolysis stabilizers but also PU prepolymers for rigid and flexible foams, coatings, elastomers, sealants and adhesives. Recent additions to the portfolio include a range of modifiers marketed under the brand name Modulast and specially developed for use in reactive polyurethane systems.

With Adiprene Green, the company has developed a range of bio-based prepolymers that benefit from the replacement of fossil polyols with commercially available, bio-based polyols.

Pellart PR 28 and Pellart PR 29 are a range of new adhesive agents for polyolefin-based materials in order to drive the transition toward water-based solutions. These primers act as an adhesive bridge between the substrate and adhesive/coating to ensure a highly durable bond.

The company is offering the industrial sector a broad range of flame retardants, including the phosphorous-based brands Levagard and Disflamoll along with the reactive, bromine-containing product PHT4-Diol. In the construction industry especially, the compounds are vital components of sustainable flame retardant solutions. Especially polymeric and reactive flame-retardant additives meet the current requirements of environmental protection and health, without this resulting in compromises in fire protection characteristics. New phosphorus-based flame retardants for rigid foams are Levagard 2000 and Levagard 2100.

Raw materials are in short supply, while pandemic-related delivery bottlenecks are affecting supply chains in a whole range of industries. Thanks to Modulast modifiers, however, the use of polyols and isocyanates in the formulations can be reduced in both TPU and CASE applications and, at the same time, physical properties can be improved.
