Sinochem News Network News recently, LANXESS's polyurethane systems business unit announced the launch of two innovative prepolymer materials in the Adiprene product series at the Polyurethane Manufacturers Association (PMA) annual meeting held in Salt Lake City, Utah, USA
.

These two products are manufactured using low-free technology, so the free diisocyanate content is extremely low

According to Ian Laskowitz, Application Development Manager of the Polyurethane System Business Unit of LANXESS, one of the most challenging applications of polyurethane casting systems is high-temperature applications
.

Over the years, with the development of polyurethane chemistry, the application of cast polyurethane systems in this high-performance field has become increasingly frequent

LANXESS used caprolactam (CAP) end-capped prepolymer and diamine curing agent to develop a unique one-component end-capped prepolymer Adiprene K LFM E820, which became the focus of the presentation of senior chemist George Brereton at the PMA annual meeting
.

Thanks to these low-viscosity end-capped prepolymer systems manufactured with low-free technology, companies can use unconventional raw materials to produce a range of chemicals, including higher-viscosity polycarbonate polyols and unique amine products

It is understood that the possible applications of blocked low-free prepolymers range from a thickness of only 1 to 2 mm to large parts weighing several tons
.

For example, these systems can be used as abrasive pad binders or industrial roller coatings, as well as industrial belt dipping
