Flammable.Flash point is 250 ℃.Melting point 263 ℃, and more than melting point temperature can sublimate to resolve, but does not melt.When the temperature to 300 ℃ release hydrogen cyanide.Higher temperatures break down into methane, hydrogen and nitrogen.Relative density (d204) was 1.331.Almost odorless.Soluble in water and chloroform.Insoluble in carbon tetrachloride, acetone, benzene and ether, insoluble in petroleum ether.Decomposition into ammonia and formaldehyde in a weak acid solution.
Pure hexamethylenetetramine is crystal, easy to form hard, difficult to disperse in the adhesive.Hexamethylenetetramine, used in the rubber industry for adhesion technology, is treated on the surface of 2% lubricant and made into a fluidity powder, or with inorganic or organic carrier made into a pre-dispersion compound.Hexamethylenetetramine can be used as a methylene donor, can form a variety of HRH direct bonding system with a variety of resorcinol donor and white carbon black, used for rubber and steel wire or fiber bonding.
In the natural rubber/carbon black material, according to HMT1.5/ rs-11, 5/ white carbon black in 13 parts, with brass plating and bare steel wire cord adhesion strength of 32N/cm and 14N/cm, respectively, without the adhesive of 21N/cm and 8N/cm.
In the natural rubber/styrene butadiene rubber (50/50) and carbon black with HMT1.6/ rs-11, 6/ silica 12 parts.
