PURL SP-32 forms a “general purpose”, closed-cell, rigid, polyurethane foam with high insulating and structural integrity. It can be sprayed or poured. The foam is spray-applied for insulating homes, roofs, factories and making artificial rocks. It can also be poured into voids such as those found in trees (arborists), boat hulls, moulds (to make ice boxes and refrigerator cabinets) and literally hundreds of other applications. PURL SP-32 foam is inert and environmentally safe and contains no ozone depleting chemicals.
