LANXESS will attend the FEICA Conference and Expo in Hamburg, Germany, from September 14 to 16. Experts from the LANXESS’ Urethane Systems and Polymer Additives business units will present low free isocyanate prepolymers for various adhesive applications, but in particular for hot melt and one-component foam (OCF) applications.
Highly efficient polymer additives for numerous special applications in the adhesives and sealants industry will also be showcased.
Sustainable Urethane Prepolymers Reduces CO2 Emissions
By using bio-based raw materials LANXESS extends its LF urethane prepolymer range for adhesives. The prepolymers provide excellent performance, processing & productivity and enable companies to reduce CO
2 emissions while helping to advance climate neutral goals.
At the conference, Ronald Emanuel, head of Research and Development at LANXESS Urethane Systems, will give a deeper insight on novel bio-based, low free isocyanate urethane prepolymers in hot melt applications.
His presentation “
Advancements in Development of High Performance, Bio-Based, Low Free Isocyanate Monomer Prepolymers for Reactive Hot Melt Adhesive Systems” will be held on Friday, September 16 at 10 a.m.
In addition to existing products such as Mesamoll, the K-FLEX® and MODULAST® brands have been incorporated into the Polymer Additives business unit, which will be present at FEICA for the first time.
Adiprene® LF - Low Free Isocyanate Urethane Prepolymer
Under the brand name
Adiprene® LF unique low free isocyanate urethane prepolymers have been developed for use in adhesives, sealants and one component foams.
The LF technology creates prepolymers with < 0.1% free MDI (methylene diphenyl diisocyanate) and other isocyanates such as TDI (toluene diisocyanate), HDI (hexamethylene diisocyanate) or pPDI (p-phenylene diisocyanate), providing unsurpassed industrial hygiene standards, excellent performance and improved processing.
The prepolymers are particularly suited to address increasingly strict regulatory requirements and provide for final products with lower hazard classifications.
Recently, the Adiprene® LF product group has been extended by Adiprene® Green LF. Adiprene® Green LF additionally offers a bio-based solution to decrease carbon emission and pave the way to a more climate friendly adhesive with excellent performance.
LANXESS’ toolbox of LF prepolymers can tailor the reactivity, viscosity and polyol backbone of the prepolymer to adjust it to the need of the formulators. By controlling the chemical structure, these prepolymers have a very structured morphology to offer more consistent processing.
MODULAST® PUR Modifier for TPU & CASE
With the
MODULAST® PUR modifier the use of polyols and isocyanates in thermoplastic polyurethanes (TPU) and CASE (Coatings, Adhesives, Sealants, Elastomers) applications can be reduced and thus the total raw material costs.
The high purity of MODULAST® PUR and its low hydroxyl value results in more complete and efficient reactions of polyol and isocyanate, thus maintaining the superior mechanical properties of polyurethanes.
The production process benefits from a reduced temperature range for molding/demolding leading to shorter cycle times.
Dibenzoate Ester Plasticizer - K-FLEX®
Furthermore, LANXESS will present its
K-FLEX® product range. These dibenzoate esters serve as plasticizers, modifiers and coalescents.
They are compatible with a wide range of polymers and can be used in adhesives, sealants, coatings, paints, flooring, wall coverings, synthetic leather, and personal care.
K-FLEX® plasticizers enable formulators to optimize both the manufacturing processes and the properties of the end products.
