Lanxess plans to invest €200m to grow global FR capacities


By Astrid Aupetit Lanxess is to invest €200m over the next three years to expand its global produc- tion capacity for flame retardants. The move comes 18 months after its purchase of Chemtura — which broadened its existing phos- phorous FR portfolio to include brominated prod- ucts — and the acquisition last year of Solvay’s phos- phorous activities in the US. “With the acquisition of the US company Chemtura in spring 2017 we became one of the world’s leading suppliers of flame retardant additives. With the invest- ment package we will further strengthen our strong position in this growing market,” said Karsten Job, Head of the Polymer Additives Business within the company’s Specialty Additives division. Lanxess estimates global consumption of flame retardants amounted to 2.25m tonnes in 2016 and cites growth rates of 3-4% annually. Phosphorous- based flame retardants account for 18% of the total and bromine-based 17%. The company operates a

bromine and phosphorous based flame retardants with production capacity at Charleston (the former Solvay site), El Dorado and Greens- boro in the US, Leverkusen and Krefeld-Uerdingen in Germany, Épierre in France, and Manchester in the UK. It also has two technical centres at Naugatuck in the US and Leverkusen. The investment an-


nouncement coincided with a flame retardants event at the Leverkusen manufactur- ing site, where the company presented some of the latest developments in phospho- rus and brominated based flame retardant and show- cased its Currenta testing facilities. Dr Heiko Tebbe, Head of

said its phosphorous FR products are mainly organic phosphate esters and are typically supplied as clear low viscosity liquids. They are predominantly used in polar polymers, with applications including flexible PVC (where they also act as a plasticiser), rigid and flexible PU foams and TPUs. The latest additions to


the product line include Levagard 2000 and 2001. Levagard 2000 is a higher molecular weight oligomer- ic alkyl phosphate ester with a 16.4% phosphorous content that offers reduced emissions; Levagard 2001 is a reactive organic phos- phate with an 18.4% phosphorous content that chemically bonds to the polymer and is claimed to eliminate emissions.


retardants are widely used in electrical and electronic applications. Dr Thomas Facklam, Head of Application Technology Business Line Polymer Additives, said the trend in terms of brominated FR technology is towards reactive and polymeric additives that are non-migrat- ing and offer low volatility. Solutions are available for use in PA, PET, PBT, PC and PC/ABS blends, as well as PU, epoxy and styrenics. He cited the example of the company’s Emerald Innovation 3000 FR, which provides an alternative to HBCD for EPS and XPS building insulation – HBCD (hexabromocyclododecane) has been identified as an SVHC under the EU REACH regulation. It is a brominat- ed styrene-butadiene polymer with a high molecu- lar weight (more than 100,000 g/mol) and a bromine content of 65%. Tests carried out by the company on XPS construc- tion boards show that Emerald Innovation 3000 provides LOI and flammabil- ity performance (DIN 4102 B2) equivalent to HBCD at the same bromine content. � www.lanxess.com
