PU(polyurethane) compound foaming material is commonly known as black material and white material, also called AB glue, foaming black and white material, black glue, white glue. The black material is isocyanate (crude MDI), and the white material is Premixed polyols. After they are stirred and mixed in proportion, a polymerization reaction occurs. It generates polyurethane rigid foam plastic with an independent closed-cell structure, featuring low density, high specific strength, excellent thermal insulation and heat preservation performance, acid and alkali resistance, aging resistance, and superior production and processing performance.
