In 1987, when the United Nations developed the Montreal Protocol on Substances that Deplete the Ozone Layer, the issue of alternatives to HCFC blowing agents was

In 1969, Bayer first reported the production of polyurethane foam using a high-pressure collision blending process and exhibited the first reactive injection molding (RIM) device with a self-cleaning and recycling mixer.

In 1974, the United States extensive use of RIM process to produce large polyurethane parts.

In 1979, the glass-reinforced polyurethane RIRIM process produces automotive fender and body panels.

In 1980, SRIM (glass fiber reinforced structural reaction injection molding) came out.

Years of research have made significant progress. In 1969, Bayer first reported the production of polyurethane foam using a high-pressure collision blending process and exhibited the first reactive injection molding (RIM) device with a self-cleaning and recycling mixer.

In 1987, the United Nations developed the Montreal Protocol on Substances that Deplete the Ozone Layer, and the alternative to HCFC blowing agents has made significant progress over 10 years of research.
