LANXESS at K 2025: Focus on additives, colorants and pigments

LANXESS will be exhibiting its comprehensive product portfolio for the plastics industry at K 2025, including diverse polymer additives, colorants and heat stable inorganic pigments for coloring plastics as well as new product developments.

 

Efficient flame retardants: Levagard 2100 and Emerald Innovation 5000

 

Levagard 2100 reactive flame retardant features high efficiency, durability and sustainability without compromising on fire safety performance. It is specifically designed for rigid polyurethane (PUR), polyisocyanurate (PIR) foams as well as closed cell spray foams used in construction and insulation applications.

 

Unlike conventional additive flame retardants such as TCPP, Levagard 2100 is a low-viscosity reactive phosphonate that chemically bonds into the polymer becoming an integral part of the matrix. This reactive integration offers several key benefits: low volatility, minimal migration, lower VOC emissions and enhanced durability – thus making it a sustainable alternative for modern insulation systems.

 

Emerald Innovation 5000 is another sustainable flame retardant designed as an alternative to decabromodiphenyl ethane (DBDPE). The product meets stringent fire safety requirements while fulfilling the latest regulatory demands in traditional and emerging markets.

 

Due to its polymeric, melt blendable characteristics, Emerald Innovation 5000 addresses the fundamental migratory issue of small molecular bromine-based flame retardant products. The product shows high permanence with low mobility when compounded into plastic resins, preventing blooming with the long-life cycle of end use cases.

 

In addition, it enables a broad processing window and tailored physicochemical properties in a variety of engineering plastic resins.

 

75 years of success: Mesamoll phthalate-free plasticizer

 

At K Fair, LANXESS celebrates the 75 years of success of Mesamoll, a phthalate-free plasticizer that enables production of flexible, durable, and long-lasting products. Its high-gelling capacity and exceptional saponification resistance allow manufacturing produces with long service-life.

 

In 2023, LANXESS Mesamoll transitioned to a more sustainable version by using carbon-reduced raw materials, offering its customers a reduced product carbon footprint by approximately 20%.

 

Hydrolysis stabilization: Stabaxol

 

LANXESS is expanding its product range of hydrolysis stabilizers for plastics and polyurethanes with the addition of Stabaxol L as monomeric and Stabaxol P LF as polymeric carbodiimide.

 

Stabaxol L shows outstanding performance when used in polyester/polylactone polyols, thermoplastic polyurethanes (TPU), other PU elastomers and polyester based polymers. In particular, its use in the polyurethane and PET monofilament applications leads to an extension of the service life of the final article under moist and warm operating conditions.

 

Stabaxol P LF is a label free sustainable hydrolysis stabilizer providing excellent protection against hydrolysis in ester-based TPEs in combination with high thermal stability, lower emission during processing. Typical applications include cable sheathing, filaments and textiles, shoe systems, rollers, engineering injection moldings and electronic housings.

 

Coloration for e-mobility: Macrolex Orange HT and Bayplast Orange TP LXS 51137

 

The colorant Macrolex Orange HT is a soluble organic dye that features excellent heat stability, excellent lightfastness and weather resistance, high color strength, and remarkable brilliance.

Unlike most conventional dyes, Macrolex Orange HT is ideally suited for key engineering plastics, which often require colorants that can withstand high processing temperatures. The halogen-free dye is characterized by consistently high quality and precise color accuracy.

 

Bayplast Orange TP LXS 51137 (Pigment Orange 68) is also designed for use in high-voltage and other engineering plastic components like housings of outdoor power tools. It stands out for its excellent weather resistance and exceptional durability.

 

Bayplast Orange TP LXS 51137 is particularly valued where maximum longevity and color stability under UV exposure and other extreme environmental conditions are required. Its robust properties ensure that plastic parts maintain their safety-critical orange coloration over many years, further reinforcing accident prevention and compliance in the e-mobility sector.

 

Automotive interior and exterior: Macrolex Black

 

In automotive applications, the Macrolex Black types offer a solution for achieving deep, piano-like black shades with exceptional gloss. These black dyes are engineered to meet the high standards of the automotive industry, providing not only intense color and excellent durability. Their compatibility with modern recycling processes further supports sustainability goals within the automotive sector.

 

New high-performance solvent dye: Macrolex Blue TP LXS 51151

 

LANXESS has expanded the range of colorants with Macrolex Blue TP LXS 51151 (Solvent Blue 122). This organic high-performance solvent dye is ideally suited for coloring polyesters, polyester fiber and other technically demanding plastics.

 

Heat stable inorganic pigments: Colortherm

 

Colortherm brand features a range of synthetic red iron oxide pigments that provide higher thermal stability.


LANXESS_K 2025_Colortherm.jpg


Colortherm iron oxide pigments.

 

LANXESS manufactures red types using its proprietary Laux process, in which the pigments are heated to up to 800°C. As a result, the micronized pigments show no visible color shift even at extremely high application temperatures and can be processed without any problems at well over 300°C.

 

For reliable yellow coloring of polymers, LANXESS offers the modular Colortherm Yellow product range. These special pigments are well suited for HDPE (high density polyethylene), PS (polystyrene), ABS (acrylnitrile-butadiene styrene) or PA (polyamide), for example.
