Summary: | The invention relates to a compound which adopts various prepolymer compound formed at least by aliphatic isocyanates, surfactant, catalyst, vesicant and water as non-yellowing polyurethane foam materials. Crosslinking agent used in the invention can be polyester-based diamine, ethanolamine or carbodiimide or the combination of polyester-based diamine, ethanolamine and carbodiimide. The foam material has high anti-yellowing performance in high heating or ultraviolet environment. The invention can be produced in a continuous production line or in dies. |
