Hexamethylene or methenamine is a heterocyclic organic compound with the formula (CH2)6N4. This white crystalline compound is highly soluble in water and polar organic solvents. It has a cage-like structure similar to adamantane. It is useful in the synthesis of other chemical compounds, e.g., plastics, pharmaceuticals, rubber additives. It sublimes in vacuum at 280 �°C. Application The dominant use of hexamethylenete tramine is in the production of powdery or liquid preparations of phenolic resins and phenolic resin moulding compounds, where it is added as a hardening component. These products are used as binders, e.g. in brake and clutch linings, abrasive products, non-woven textiles, formed parts produced by moulding processes, and fireproof materials. Medical uses As the mandelic acid salt (methenamine mandelate) or the hippuric acid salt (methenamine hippurate), it is used for the treatment of urinary tract infection. Histological stains Methenamine silver stains are used for staining in histology, Solid fuel Together with 1,3,5-trioxane, used by campers, hobbyists, and relief organizations for heating camping food. Reagent in organic chemistry Hexamethylene is a versatile reagent in organic synthesis. It is used in the Duff reaction (formylation of arenes), the Sommelet reaction (converting benzyl halides to aldehydes), and in the Delepine reaction (synthesis of amines from alkyl halides). Explosives Hexamethylene is the base component to produce RDX

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)
