EXOstab NP200 is an auxiliary agent used for the production of rigid polyurethane nonylphenol-based foam. The product is provided in the form of clear or lightly murky liquid, with a pour point of -20°C, hydroxyl number of 56 mg KOH/g and functionality of 1. It is recommended for systems, where n-pentane and water constitute foaming agents.
The product significantly improves compatibility of polyol and foaming agent. EXOstab NP200 has a positive impact on the system miscibility by generating emulsion stable over time. Furthermore, it substantially limits the loss of the foaming agent while mixing the preparation. Thanks to the additive, the ready-to-use foam has finer cell structure and is smoother to the touch. The suggested dosage is in the range from 3 to 10% of the polyol mass. The product does not contain any derivatives of silicon.
