Lanxess Addovate® WM PU Additive
Categories: Other Engineering Material; Additive/Filler for Polymer

Material Notes: Function: Dispersant and emulsifier for the production of polyester based flexible slabstock foam.

Product information: Addovate WM is an emulsifier for water, paraffin oil and water-insoluble catalysts (e.g. Addocat DB) in polyester-polyols with OH-value of approx. 60 mg KOH/g. This emulsifier is used for the production of polyester slabstock foam with TDI 65. Addovate WM is used in combination with Addovate SM and if necessary Addovate LM (prevents core discoloration). In general 1.0 - 2.0 p.b.w. of Addovate WM should be added to 100 p.b.w. polyester polyol. Over-dosage (> 4.0 p.b.w.) of Addovate WM will result in a deterioration of the compression hardness. Under-dosage of Addovate WM leads to a badly homogenized catalyst mixture which results in severe damages to the cell structure. Should a silicone stabilizer be processed which emulsifies Addocat DB not sufficiently, it is recommended to add a sufficient amount of Addovate WM (approx. 0.5 - 1.0 p.b.w.).
