Polyurethane Foam

       Polyurethane foam is divided into two categories: chemical foaming and physical foaming. It undergoes three stages: expansion, gelling, and curing, and can be applied through spraying, casting, or molding. The foamed products feature light weight, thermal insulation, and energy absorption, and are categorized as soft foam (pored, high elasticity) and hard foam (closed cell, high rigidity). They are widely used in building insulation, automotive seats, cold chain equipment, and furniture fillings. By adjusting the catalyst, foaming agents (water or fluoro-carbon), and raw material ratios, the bubble density, hardness, and temperature resistance can be precisely controlled to meet requirements for soundproofing, vibration reduction, or energy saving.
