Foam rubber - Wikipedia
Foam rubber (also known as cellular rubber, sponge rubber, or expanded rubber) is rubber that has been made with a foaming agent so that its structure is an air-filled matrix. Commercial foam rubber is generally made of synthetic rubber, natural latex, or polyurethane. Latex foam rubber, used in mattresses, is well known for its endurance.
Chemistry, Processing, Properties, and Applications of Rubber …
2021年5月13日 · Rubber foaming relies on the expansion of a gaseous phase dispersed throughout the rubber melt. In porous materials, the pores are usually divided into two types: open cells which are interconnected throughout the material and also connected to the ambient environment, and closed cells where the gas is dispersed as separate/individual bubbles ...
