Pittsburgh-based foam industry supplier Covestro LLC, formerly Bayer MaterialScience LLC, has added a new line of methylene diphenyl diisocyanate polyols that yield superior visco-elastic bedding foams, according to a news release.
Covestro, which is part of the Bayer Group, with world headquarters in Leverkusen, Germany, said the new MDI-based formulations build on the success of its Softcel VE-1100 polyol.
“(The new offerings) provide manufacturing simplicity and improved foam quality,” said Susan McVey, manager of Covestro’s Flexible Slabstock Foam Applications Development Group. “Flexible polyurethane foams made with the new polyols offer enhanced comfort properties—improved airflow, better compression set and enhanced tear strength—and meet changing industry testing and environmental standards. … This combination of raw material choices along with new formulations should offer improved comfort for the consumer in getting a cooler sleep and better physical properties which could translate to reduced handling costs and potentially less bedding returns or complaints.”
Covestro researchers provided details about the new formulations in an Oct. 5 presentation, “Expanded formulation options for producing new viscoelastic foam grades,” at the 2015 Polyurethanes Technical Conference in Orlando, Florida.
