LANXESS: new polyurethane prepolymers for the construction industry

LANXESS has developed a new generation of polyurethane prepolymers for the construction indust.

The construction industry is currently undergoing a radical chan.

Globality and R&D expertise

With the acquisition of Chemtura, LANXESS established the polyurethane portfolio business as an independent corporate business un.

Prepolymers are the key to superior performance

Another innovation is a new generation of prepolymers developed for the construction industry with very low levels of free isocyanate monome.

Adhesives and sealants based on LF prepolymers provide the industry with optimum hygiene conditio.

highly ordered structure

The use of LF isocyanate prepolymers results in excellent properties in formulated polyurethane produc.

Constant isocyanate content, adjustable viscosity

By using LF technology, the viscosity of the prepolymer can be controll.

Examples of LF prepolymers based on MDI (methylene diphenyl diisocyanate) and polypropylene glycol show how the viscosity chang.

LF prepolymers for hot melt adhesives have high crystallinity polyols

The low viscosity of the LF prepolymer also has benefits in reactive hot melt adhesive reaction syste.

The development of MDI-based LF prepolymers by Polyurethanes is one examp.

"Well Filled Building Kit"

        In addition to curing agents and additives, the polyurethane portfolio offers a wide range of isocyanates and polyols that can be tailored according to modular design principl.
