POLYETHER ESTERS AS FLAME RETARDANTS FOR POLYURETHANE FLEXIBLE FOAMS |
摘要 |
Flexible polyurethane foams that satisfy the requirements of FMVSS 302 are produced by reacting a polyisocyanate with a polyol component that includes: (1) from 90 to 99 parts by weight of a polyether polyol having an OH value of from 20 to 200 mg KOH/g and functionality of from 2 to 4 and (2) from 1 to 10 parts by weight of a polyether ester polyol having an OH value of from 150 to 450 mg KOH/g and a functionality of from 2 to 3 in the presence of a blowing agent, catalyst and stabilizer. The foams thus produced are useful as cushioning for furniture and automotive applications.
