Описание материалов:
Baytec MP-090 is a modified diphenylmethane diisocyanate (MDI)-terminated polyether prepolymer based on polypropylene ether glycol (PPG). This prepolymer is used in the manufacture of cast polyurethane elastomers. As with any product, use of Baytec MP-090 prepolymer in a given application must be tested (including field testing, etc.) in advance by the user to determine suitability.
