Description

1. Hexamine
We have two type of hexamine, one is stabilized, with 0.3%*0.5% anti-blocking agent(benzoic acid or silicon dioxide) the other is unstabilized. Also have small particles, can reach **0mech, mainly used for high class plastic industry.
Hexamine is a white crystal. Without toxicity and odour. It tastes sweet at first and bitter then. The specific gravity D*5/4 is 1.*7 . it is souble in gasoline, ketone and so on.
It is curing agent or catalyst in plastic industry, sulfuring accelerator in rubber industry, shrink proof agent in weave industry, food antiseptics, emictoria and is used for the production of hesokin explosive. The product has been applied widely.
2.paraformaldehyde
English name:      paraformaldehyde; polyoxymethylene
Molecular formula:  (CH2O)n
Appearance:       with crystal powder, have formaldehyde smell
Molecular weight   (*0)n.
Pressure:         0.*9kPa/*5℃
Flash point:       *0℃
Paraformaldehyde is used as synthetic resin, adhesive, also as pesticides, fumigant, and for the preparation of pure formaldehyde.
3. Formaldehyde
Formaldehyde is a colorless, have a strong smell of gas stimulus type. Soluble in water, alcohol and ether. Formaldehyde is a gas at room temperature, usually in the form of aqueous solution. Soluble in water and ethanol, *5%~*0% formaldehyde liquor called formalin. Formaldehyde is a kind of important organic raw material mainly used in the plastics industry (such as synthetic phenolic resin, urea-formaldehyde plastic-electric jade), synthetic fibers (such as synthetic vinylon-polyvinyl formal), leather industry, medicine, dyes, etc..
4. Melamine
Melamine (C3H6N6), commonly known as melamine, protein power, it is kind of important organic chemical middle products. It condenses with formaldehyde to product the formaldehyde resin(melamine resin), and owns the advantages of unharmful, heat-resisting, anti-aging, high-lustre, good insulation and widely used in the fields of plastic processing and wood working, is also the chemical raw material of coating, papermaking, textile. Paints and leather processing industry.
5. pentaerythritol
Pentaerythritol is used in the manufacture of alkyd resins, fatty acid rosin and tall oil esters and to make paint and coatings, printing ink, coating adhesives, explosives, sealants, varnish, lacquer vinyl chloride, synthhetic rubber and miscellaneous including pentaerythritol tetranitrate(PETN), urethane coatings, flame retardant paints, polyvinyl chloride stabilizers, olefins antioxidant and pentaerythritol triacrylate.
