Rebecca KekanaQ : Hello,I want to konw sth about your sodium acetate trihydrate.Is it the substance used in body warmers, also known as hot ice? If so, then is it possible to make it hotter when it solidifies? Thank you
FOODCHEM A : Thanks for consualting.It'is well konw that sodium trihydrate tech grade can be used in producing body warming products,for example,hot ice; By clicking on a metal disc in the heating pad, a nucleation centre is formed which causes the solution to crystallize into solid sodium acetate trihydrate again. The bond-forming process of crystallization is heat released.We will be honoured if you esteemed company give us the chance to provide best quality sodium acetate trihydrate products.
