General
Polyurethane parts can be made by the RIM (reaction injection molding) process. Raw materials are injected into a mold where the polymerization occurs. Depending on the end-use of the product, enhanced light and/or long-term thermal stability may be required.
Very often coloration of molded foams and RIM parts is done by means of adequate organic pigments. Especially for RIM-parts the in-mold painting process has been developed.
A major user of RIM /Molded foam articles is the automotive industry with its stringent performance requirements. Consequently, high light stability and thermal stability as well as light fastness of colors of all shades and the use of other additives, such as antistatics, may be needed. A proper selection of additives to avoid or at least minimize fogging may be of particular interest as well.
