PTA is one of the important bulk organic raw materials, widely used in chemical fiber, light industry, electronics, construction and other aspects of the national economy. At the same time, the application of PTA is more concentrated. More than 90% of PTA in the world is used to produce polyethylene terephthalate (PET). It needs 0.85-0.86 tons of PTA and 0.33-0.34 tons of MEG to produce 1 ton of pet. Polyester includes fiber chip, polyester fiber, bottle chip and film chip. In the domestic market, 75% of PTA is used in the production of polyester fiber; 20% is used in the production of bottle grade polyester, mainly used in the packaging of various drinks, especially carbonated drinks; 5% is used in film grade polyester, mainly used in packaging materials, films and tapes. It can be seen that the downstream extension product of PTA is mainly polyester fiber. Application: PTA is mostly used in the production of polyethylene terephthalate (polyester). It is an important raw material for polyester fibers, films, plastic products, insulating paints and plasticizers. It is also used in dyes and other products' production.

What is Sodium octanoate ? In the pharmaceutical industry, biological agents (human albumin) contain sodium caprylate as an inactive ingredient. In biological aspects, higher acid salts are generally used for special breeding of bacterial species. The reason why salts are used is that salts have greater solubility than higher acids themselves. And the PH value is better adjusted. For example, when breeding bacteria that can degrade caprylic acid, sodium caprylate needs to be added to the culture medium. Application of Sodium octanoate Sodium caprylate is used as a protein stabilizer in biological preparations.
Hexahydro-1,3,5-Tris(hydroxyethyl)-S-Triazine is a triazine derivative contained in cutting fluids. It is a formaldehyde releaser. Hexahydro-1,3,5-tris(hydroxyethyl)-s-triazine is an amine and an alcohol. Amines are chemical bases. They neutralize acids to form salts plus water. These acid-base reactions are exothermic. The amount of heat that is evolved per mole of amine in a neutralization is largely independent of the strength of the amine as a base. Amines may be incompatible with isocyanates, halogenated organics, peroxides, phenols (acidic), epoxides, anhydrides, and acid halides. Flammable gaseous hydrogen is generated by amines in combination with strong reducing agents, such as hydrides. Hexahydro-l,3,5-tris-(2-hydroxyethyl)triazin is used in organic synthesis; as a bactericide in cooling fluids and various cosmetic products; formaldehyde liberator. Hexahydro-1,3,5-tris(hydroxyethyl)-s-triazine is probably combustible. It is a triazine derivative contained as a bio cide in cutting fluids. It is a formaldehyde releaser. Dermatitis, delayed-type allergic conjunctivitis, and asthma were described.

Cardiovascular protection: Astaxanthin can reduce cholesterol accumulation and oxidative damage, which is helpful in preventing atherosclerosis, hypertension and other cardiovascular diseases. Enhance immunity: The antioxidant properties of astaxanthin can enhance the function of the immune system, improve the body's immunity, and help prevent infections and diseases. Improve skin: Astaxanthin can improve skin elasticity and gloss by reducing the production of free radicals and stimulating collagen production, which is helpful in preventing skin aging and wrinkles. Relieve eye problems: Because astaxanthin can penetrate the tissue of the eye, it has a certain effect in protecting and relieving eye problems, such as reducing eye fatigue and improving vision.
D-Chiro Inositol (DCI) is a member of a family of substances referred to as inositols and generally considered to fall within the B vitamin complex.It can be found in small amounts in a range of foods such as buckwheat, chickpeas, soya lecithin, pumpkin and pumpkin seeds as well as in the Ayurvedic herb bitter melon (momordica charantia). It is also produced by healthy human bodies from d-pinitol and myo-inositol, both of which are relatively abundant in the average diet. It is a nutrient found in the body itself, which allows the body's cells to recognise it better and not reject it. 1994, the US Dietary Supplement Health and Education Act approved D-chiral inositol as a dietary supplement.
