The styrax benzoin tree is evergreen, and grows naturally in northern sumatra, indonesia.
The tree yields an almond shaped solid gum resin called benzoin gum sumatra (cas number: 9000-05-9), collected from incisions made into the trunk of the tree.
The gum resin is of high quality and has many commercial uses.
Gum benzoin sumatra is used as raw material in a variety of industries.
In perfumery in particular, benzoin is widely used as a fixative, with its warm scent able to blend with other fragrances, and its ability to slow the dispersion of essential oils and other fragrance materials into the air.
In pharmacy, sumatran benzoin is used for its excellent antiseptic, astringent and expectorant properties. It is used in products for the treatment of skin problems, wound healing, bronchitis, catarrh, upper respiratory tract infections, ulcers, fever, inflammation, cough, and in more general skin care products.

Note: for benzene soluble polyamide resin: the inspection conditions of viscosity & chroma: solid is 40%, solvents are xylene/ isopropanol/ absolute alcohol (4:3:3), viscosity method is rotation method. For solubility: the solution is 40% of resin solution, the ratio just like viscosity inspection.
For alcohol soluble polyamide resin: the inspection conditions of viscosity & chroma: solid is 50%, solvent is 95% ethanol, rotation method (hj-2000); the inspection conditions of viscosity & chroma: solid is 40%, solvents are isopropanol/absolute alcohol/normal butyl alcohol (1:1:1), rotation method (hj-2003). For solubility: the solution is 40% of resin solution, the ratio just like viscosity inspection.
PBT resin is one of the top five common engineering plastics. It possesses the following good properties,i.e chemical resistance, abrasion-proof, low friction coefficient, low wet absorption, easy coloring ,fine surface gloss as well as fine electrical, heat mechanical & processing properties. It is widely used in various trades e.g electronics, electricity, optical fiber cable, automobile, communication, information, illumination household electrical appliances and machinery.
