solid state physics - When I stretch a rubber band, it breaks. When I hold the broken ends together, why doesn't it join again?


The question is simple. When we join the two broken surfaces, what is it that keeps the surfaces from connecting with each other, while earlier they were attached to each other? Also, would the two sides join again if I hold them together for an infinite amount of time?
