| Emulsifier for the production of polyurethane ester flexible slabstock foam Polyester flexible slabstock foam for "textile" application: Addovate EM is normally used in combination with Addovate TX for the production of polyester flexible slabstock foam. Addovate EM is used as an emulsifier for water, catalyst (e.g. Addocat 101, Addocat PV, Addocat 117) and the polyester polyol. Addovate EM also improves the open-cell structure of foams. The amount which should be used is between 1.0 and 4.0 parts by weight Addovate EM to 100 parts by weight polyester polyol. The following sequence has proven effective for adding the individual components when manufacturing the catalyst compound: Water, catalyst, Addovate EM, Addovate TX, so a clear, homogeneous mixture is produced. "Low odor" polyester flexible slabstock foam: For the production of "low odor" polyester flexible foam is used as emulsifier/ stabilizer Addovate EM in combination with Addovate 3240 and small amounts of silicone stabilizers.
