A.Product:Thiourea dioxide,another name for Formamidinesulfinic Acid
Molecular Fonmula:(H2N)2CSO2

&＃8544;.Physical & Chemical Composition

&＃12288;1.The product is of ctystal appearing white or light yellow.It digests at the melting point 126&＃8451;.It's a kind of compound of Reducer and anti-oxidant.The odor of liquor is lightly acid.
&＃12288;2.Ramaims stable in acid liquor,but decomposes rapidly under usual conditions.The formamidinesulfnic acid as a result of digestion is of strong reduction and enables coutrollable reducing ability of the product.
&＃12288;3.Compared with safty powder,the reduction potential of the product is higher and of lower decreas speed the decreasing only amount to 1/5 or the safty powder's.
&＃12288;4.The product has good resist temptation stability,in a state of drier it remains stable below 70&＃8451;.
&＃12288;5.The product has good safety reliability.Thers is no pollution during producing and using.

&＃8545;.Scope and Field of Application

&＃12288;1.As reducing agent in printing & dyeing industry.As bleach & reduce dyestuff for cotton,wool,and chemical fiber .As reducing agent for sulphard dyestuff.Also be application to textile in printing of disperse dye,striping, reprocession and floating color removing,etc.
&＃12288;2.Can be used in pulp bleaching in paper manufacturing industry.
&＃12288;3.As emulsion sensitizer being token in industry,it enables high stability of the exposure part of photographic paper.
&＃12288;4.As modified catalyst for chemical fibre.It defend the modified fibre from turning yellow.
&＃12288;5.As oxygen resister in organic compounding.
