- Abstract
- Spectacular progress has been made in the field of cellular materials in the last ten years. A constant stream of technical information has been disclosed in a mounting number of publications, and a wide variety of new products has become commercially available. By far the largest segment of materials is represented by foamed plastics. Also known as cellular or expanded plastics, they can be made in flexible, semirigid, or rigid foams, in densities which in some cases have been as low as 0.1 lb/cu ft to as high as 80 lb/cu ft. For most applications, properties such as low density and high strength-to-weight ratios are of importance, while in many other instances their good thermal and electrical insulating properties make them very desirable. Some foams excel in impact absorbing capacity, vibration damping, and acoustical insulation, while others are characterized by outstanding abrasion and chemical resistance.
