Polyurethane foam - Names and Identifiers
Polyurethane foam - Introduction
Polyurethane foam is a synthetic material with many useful properties. Its main component is polyurethane, and the foam structure is formed by injecting gas into the material during the manufacturing process.
Polyurethane foam has several different properties, including good insulation properties, low density, lightness, elasticity and chemical resistance. These properties make Polyurethane foam widely used in various fields.
Polyurethane foam is often used in the construction field as an insulation material and structural support material. It can be used in building walls, roofs and floors for heat insulation, sound insulation or to increase structural strength. Polyurethane foam can also be made into upholstery, mattresses and seats and other furniture and automotive interior materials to provide comfort and reduce vibration. In addition, it can also be used in packaging, refrigerated vehicles and refrigeration equipment to maintain a constant temperature and prevent leakage.
The method of manufacturing Polyurethane foam is by reacting two or more compounds, one of which is a polyalcohol and the other is a polyisocyanate. These compounds form a macromolecular network during the reaction and form a foam by simultaneously generating a large number of bubbles.
