Usually the stabilized hexamine is added with 0.2%~ 0.3% anti-blocking-agents so that it is not easy to block. However, we found a method for our products to avoid blocking without anti-blocking-agent. We are glad to provide free samples for you, and if you want to come to visit the factory, we are enthusiastic about your visiting. We also have other two types of hexamine: unstabilized hexamine (fine powder) and ultrafine hexamine (mesh size: 120/150 mesh). Hexamine is widely used in curing agent or catalyst in plastic industry, sulfuring accelerator in rubber industry, shrink proof agent in weave industry, food antiseptics, emictoria and the production of hesokin explosive. The specific gravity of our products is d25/4 = 1.27. In 25 kgs woven bags or kraft bags (one 20¡¯fcl=21~22mts without pallets & 18~20 mts with pallets)
