Application Areas

WANNATE® PM-200

can be widely used in the manufacture of rigid polyurethane foam insulation materials; it can also be used in isocyanurate foam, coatings, adhesives, anti-seepage and plugging, structural foam, microcellular integral skin foam, automobile insurance Bars, interior parts, high resilience foam, synthetic wood and other fields. Due to its unique composition and structure, it has good foam flow performance, and is also suitable for the manufacture of products that have strict requirements on the flow performance of foaming stock solution.

Polyurethane rigid foam is mainly used as thermal insulation material and structural material in house construction. High-density polyurethane rigid foam can be used as housing brackets, window frames, window sashes, window frames, doors, etc. Ordinary density polyurethane rigid foam can be used as roof gutters, vents, ceilings, water tanks, heat insulation layers of flat roofs, walls of industrial building structures, insulation walls of cold storage buildings, etc.
