Wanhua WANNATE® MDI-50 is a polymeric methylene diphenyl diisocyanate (PMDI) widely used in the production of rigid polyurethane foams. It offers excellent reactivity and flowability, making it ideal for applications such as insulation panels, refrigerators, construction boards, and pipe insulation. Its superior insulation properties help reduce energy consumption in buildings and appliances. MDI-50 is also used in spray foam for roofing and wall insulation, and as a binder in composite wood products like oriented strand boards (OSB). Its versatility, processing ease, and performance make it a preferred choice in thermal insulation and industrial materials.

Wanhua Chemical WANEFOAM® RNP2 is used in polyurethane foam production to improve cell structure, enhance insulation performance, and increase foam stability. It helps optimize processing efficiency, supports uniform foam expansion, and is suitable for applications such as construction insulation panels, appliances, refrigeration, and industrial foam systems.
