Polymer Additives

Smooth, fireproof and colorful
Our Polymer Additives business unit is one of the world's leading manufacturers of bromine, bromine derivatives and phosphorus chemicals. These serve as building blocks for the production of complex molecules. Application examples include flame retardants, oil production, agrochemicals, pharmaceuticals, fine chemicals, butyl rubber, polymers and biocides, paints & coatings, and colorants for plastics or for inkjet printing inks.

Our product portfolio includes a large variety of other polymer additives such as plasticizers, hydrolysis stabilizers, and also solutions for water treatment.

Additives are the unsung heroes of the chemical industry - But how exactly do these ingredients change the properties of products?

Flame retardants

With brominated and phosphorus-based solutions, LANXESS offers one of the most comprehensive ranges of organic flame retardants in the world. Our newly developed polymeric and reactive flame retardants can reduce the release of additives from the polymers, thus contributing to environmental and health protection without compromising fire safety.

Due to their high efficiency brominated flame retardants are frequently used in the construction and electronics industries.

In addition to highly efficient fire protection, phosphorus-based flame retardants offer further advantages such as good processability and high elasticity in PU and PVC systems.
These additives are used in the manufacture of flame-retardant articles, including insulation, cables, printed circuit boards, foils, tarpaulins, floor coverings, seat covers, and fire protection applications.

Flame retardants from LANXESS delay the spread of fire in vehicles - and put criminals in risky situations.


Plasticizers ensure elasticity and flexibility of polymer materials. But this is not their only benefit. Plasticizers also optimize, for example, the processing properties of polymer materials, which leads to improved product quality or even new properties. The choice of plasticizers depends on the demand placed on the finished product. These can include greater softness, elasticity, adhesion, flame retardant properties or resistance to chemicals, weathering and migration.

Hydrolises Stabilizers

Polymers that are produced by polycondensation generally display a weakness when attacked by water or moisture. Our Stabaxol® hydrolysis stabilizers are suited to improve the hydrolysis resistance of polycondensates such as PET, PBT, PU, TPU and PA to expand their range of applications.

Product: Stabaxol®


Water treatment chemicals

Whenever scale inhibition in water circuits or wastewater treatment are required, LANXESS products are used to stabilize the water hardness, control corrosion and disperse solids effectively. Specialties of LANXESS are used in industrial processes such as traditional water treatment circuits, once-through cooling processes as well as in surface cleaners, personal care products and detergents for private use.

Products: Bayhibit®, Baypure®, Epiphos®, Mersolat®


Bromine and phosphorus performance products

Bromine, bromine derivatives and phosphorus specialties serve as building blocks for developing and engineering highly complex organic molecules.
Bromine, brominated intermediates and phosphorus chemicals are utilized in many applications including flame retardants, agrochemicals, pharmaceuticals, fine chemicals, high performance rubber, polymers and biocides.

Products: Baysolvex®, Tri- and Dibutyl phosphates, phosphorus chlorides, phosphites, phosphorus oxides and polyphosphoric acids
