Definitions for "Polyether"
raw material for polyurethane production
A polymeric polyol containing ether linkages (carbon-oxygen-carbon links) in the main molecular chain or in side chains.
A family of organic polymers characterized by the presence of ether groups R-O-R within the molecule. Polyethers can be prepared to have reactive hydroxyl groups and thus can be used as a polyol in the preparation of polyurethane foam. Ethers are less susceptible to hydrolysis than esters.
A chemical building block used in place of polyester in some VIBRATHANE prepolymers, e.g., B-600 and B-615. The polyether provides outstanding resilience, and hydrolytic stability.
