Lanxess Addolink® B PU Additive
Categories:	Other Engineering Material; Additive/Filler for Polymer
Material Notes:	Addolink B is used as a chain extender or crosslinking component for polyester and polyether casting elastomers (hot and cold) and for integral skin foam. The reaction between Addolink B and isocyanates leads to the formation of the hard polyurethane segments. The rapidity with which these hard segments are formed in the reaction mixture reduces the demolding time. The use of Addolink B also affects the physical properties of the finished product. It increases the material's hardness and improves the resistance to abrasion and heat. The addition of Addolink B depends on the needs of the finished product and can be varied between 2 and 10 parts by weight, calculated on 100 parts by weight polyol. As the freezing point of Addolink B is relatively high, temperatures above 22 °C are needed for satisfactory processing. Function: Standard crosslinking agent for the production of polyurethane elastomers (hot- and cold-curing cast systems) and of integral skin foams. Information provided by Lanxess.
