Development of natural rubber foam by in-house Talalay method

Abstract The benefits of natural rubber foams (NRFs), include its buoyancy, sound absorption, supportability, and low weight. Generally, there are two main techniques to produce the NRFs: Dunlop method Talalay method. technique is a cheap conventional method, while complicated (cool down, vacuum heating process). objective this research study difference properties NRFs between methods. Both proposed with similar foam density values. mechanical NRF from in-house were lower than those obtained by may due generating large bubble system. However, FTIR spectrum both methods showed same functional groups.
