[Chemical Knowledge]：Reveal the magic of foam materials

Read： 826 Time：20months ago Source：Transform the World with Simplicity

Foamed material is a material that can rapidly expand under the action of heat or foaming agent to form cells. They have the characteristics of low density, high sound absorption, heat insulation, and softness. At present, foam materials are widely used in automobile, construction, packaging and other fields, and have brought huge economic and social benefits to all walks of life.

foam materials are widely used in the automotive field. Foam materials can effectively reduce the quality and noise of automobiles, and improve the safety and comfort of automobiles. At present, many automobile manufacturers are beginning to use foam materials for car seats, roofs, doors, dashboards and other parts. For example, Toyota Motor Corporation of Japan applied the foam material to the door sound insulation cotton, which reduced the internal noise of the car by 1-2 decibels, and increased the external sound insulation effect of the door by more than 20%.

foam materials are also widely used in the construction field. For example, foamed polyurethane is used for thermal insulation materials to improve the energy-saving performance of buildings. In addition, expanded polystyrene is also widely used in wall insulation and roof insulation. Foam materials can not only improve the energy-saving performance of buildings, but also improve the sound insulation performance of houses and provide a better living environment.

third, foam materials are also widely used in the field of packaging. Foamed materials can protect items from impact, vibration and chemical effects, thereby reducing the rate of damage. At present, many companies have begun to use foaming materials for packaging products, including electronic products, cosmetics, alcohol, etc.

Finally, some companies have made breakthroughs in the field of foaming materials. For example, the American Huntsman Company has developed a new type of polyurethane foam material with better elasticity, high water absorption and thermal insulation properties. In addition, Dow Chemical has developed a new type of polystyrene foam material with higher compressive strength and better corrosion resistance.

To sum up, foamed material is a material with wide application prospect. They have the characteristics of low density, high sound absorption, heat insulation, softness and earthquake resistance, and can be widely used in automobile, construction, packaging and other fields. In the future, with the continuous progress of science and technology and the continuous innovation of material technology, the performance and application scenarios of foaming materials will continue to expand.
