The materials that made good insulators are plastics, ceramics, fibreglass, delrin, acetate, acrylic, glass, mica, kapton, melamine, neoprene, nylon, polyester, polyolefins, silicon rubber and many more. Several foams are usually laminated with a heavy layer to develop a vibration barrier and a sound.
A material is a good insulator if the fibres making it are poor conductors of heat. Insulators can then stop heat from being transffered into an object as well as stopping heat being transferred out of an object. A good insulator keeps things warm for longer.
