Hot melt adhesive (HMA), also known as hot glue, is a form of thermoplastic adhesive that is commonly supplied in solid cylindrical sticks of various diameters, designed to be melted in an electric hot glue gun. The gun uses a continuous-duty heating element to melt the plastic glue, which the user pushes through the gun either with a mechanical trigger mechanism on the gun, or with direct finger pressure.
Its molecules are in both ether bonds and carbonyl groups, and the carbonyl groups are formed the structure of ester, while they contain alkyl groups. In the same molecule, there are both non-polar parts and polar parts. The functional groups of these two parts are mutually restricted and excluded, and each has its own inherent function. Therefore, it has a certain dissolving ability to the non-polar substances and polar substances.
Water white, high hardness, yellowing resistance, good brushing, high fullness
It is slightly soluble in water and acetone, but can be soluble in the most organic solvents such as, alcohol, ether, ketone and others.
It is a four primary alcohol, bipolymer of trimethylol propane
2-Methoxy-1-Propanol has both hydrophobic covalent ether bond and hydrophilic hydroxy group in its molecular structure. So it has high solubility to both oily and aqueous resins. Its hydroxy group still has reactivity to enable it to act as chemical intermediate.
This product is white crystalline. It is easily dissolved in alcohol, ether, acetone, and slightly dissolved in water. Its boiling point is 270-280℃.
Antimony metal, also called antimony ingot, is smelted from antimony ore, mining. It is the antimony concentrate from nature and is the raw material for many antimony products.
It is soluble in water and acetone, and also soluble in carbon tetrachloride, chloroform and ether, but insoluble in aliphatic hydrocarbon and aromatic hydrocarbon.
Sodium formate a kind of white crystal powder. Soluble in water, ethanol, nontoxic, noncorrosive, with reducing performance, capable of reacting with strong oxidizing agent, freely slaked in air. It can used in leather industry,the camouflage acid of chrome tanning,catalyst and stable compound,the reducing agent of printing and dyeing industry,the production of sodium hydrosulfite,oxalic acid and formic acid,the precipitation of precious metals.
