LANXESS, a specialty chemicals company, launched new UTECH in Europe in 2018 Low free monomer product , for adhesives and sealants. With its Adiprene LF product, the company's Polyurethane Systems business unit provides applications for low-free polyurethane prepolymer products (Adiprene LF), castable elastomers, coatings, adhesives and sealants. Excellent performance and industrial hygiene. The company is a leading innovator in the development of low-free (LF) isocyanate technology based on which it develops products.
'The focus of our development work is to expand the range of low free isocyanate prepolymers and continuously reduce the maximum content of free isocyanates' Head of Polyurethane Systems, Dr. Markus Eckert explain.
The range of low free polyurethane prepolymer products (Adiprene LF) has been expanded to include less than 0.1% of free MDI, which is used in adhesives and sealants applications. These new low free prepolymers provide three main the benefits of:
● Free MDI less than 0.1%
● Improve industrial hygiene
● Excellent performance, easy processing
Improve industrial hygiene
Low free polyurethane prepolymers can minimize exposure to free isocyanates, and isocyanate exposure is also an added regulatory issue. LANXESS is the only manufacturer to provide less than 0.1% free isocyanate prepolymer with its extensive chemical supply Including MDI, IPDI, HDI, TDI and PDI. This specialty chemical company is also constantly striving to expand its existing chemical range.
Low-free polyurethane prepolymers can improve industrial hygiene during processing and handling. At the same time, products protect workers and users from potential isocyanate exposure, reduce EH&S workload, and reduce production risk levels. Eckert said: 'Our low free prepolymer meets the latest regulatory standards for industrial hygiene and worker safety, so this formula can reduce the protective measures required for the original chemical.'
Excellent performance, handling and productivity
Low free polyurethane prepolymers provide superior chemical structures, including wetting and covering viscosities, improved tensile and tear strength for adhesion, and resistance to harsher environments from heat, moisture and chemicals Force. The unique synthesis of these prepolymers also stabilizes the performance of each batch.
Low free polyurethane prepolymers allow formulators to simplify their processing. Compared to traditional alternatives, the product achieves low viscosity and reduces the use of solvents by the formulator. By controlling the chemical structure, these prepolymers are Provide more consistent processing during opening hours.
'These prepolymers are used for the most demanding applications,' said Eckert. 'Using low-free technology, our scientists can customize the prepolymer to achieve the performance and processing characteristics that the formulator needs.'
LANXESS's Polyurethane Systems business unit, which provides polyurethanes for elastomers, coatings, adhesives and sealants, is one of the world's leading suppliers of polyurethane systems. The company focuses on solvent-free and monomer-free systems and provides customers with decades of experience. Polyurethane chemistry knowledge, comprehensive application expertise and deep manufacturing experience.
