LANXESS launches bio-based prepolymer line Adiprene Green

By OEM Update Editorial September 4, 2020 5:03 pm IST

Specialty chemicals company LANXESS has developed a new range of MDI polyether prepolymers containing renewable, bio-based raw materials. Marketed under the brand name Adiprene Green, the products are suitable as replacement for existing fossil based polyether prepolymers to manufacture highly durable polyurethane (PU) elastomers.

The overall objective to develop Adiprene Green was to create a range of bio-based prepolymers which allow the PU processor to produce components with a reduced CO2 footprint. Depending on the system, a reduction of CO2 between 20 to 30 percent is possible compared to fossil-based prepolymers due to the use of polyether polyols based on starch. The share of bio-based raw materials varies between 30 to 90 percent dependent on the targeted system hardness. At the same time the existing PU processing capabilities would remain applicable and the properties of the final polyurethane elastomer would be similar to established elastomers based on fossil based polyether or even better.
