Other name: Fluorescent brightener C.I.393
CAS NO: 1533-45-5
Appearance: Greenish yellow powder
Purity: 98.5%Min
Melting point: 355-360°C
Solubility: insoluble in water,but soluble in high boiling point organic solvent such as phenyl-chloride
Properties: Does not dissolve in water, can dissolve in such high boiling point solvents as trichlorobenzene, diphenyl ether,etc.; Because this product has high melting point and strong stability,so it has very good heat resistance; Because this product's hydrophobic nature, so it has good light fastness; and for it has strong fluorescence, it can not only improve the whiteness of the products but also can improve the brightness, so it can be used as disperse dyes in the chemical fibre, can be used like oil dissolving coloring agent in the plastics.
Uses:1.Suitable for whitening chemical fibers, such as the polyester fibre, nylon fiber, polypropylene fiber and so on.2. Suitable for whitening and brightening polypropylene plastic, hard PVC, ABS . EVA, polystyrene, polycarbonate, etc.3. Suitable to be added into the conventional polymerization of polyester and nylon.4. Especially suitable for whitening the plastics of elevated temperature.


Safety management:

This product can be managed according to general industrial chemicals. Gloves and protective glasses should be worn to avoid direct contact with skin or eyes. If stained with skin, rinse with clean water and soap.

Ultra-high molecular polyethylene (UHMWPE) is a high-performance material with excellent strength, rigidity and wear resistance. It is not limited by ordinary polymer materials, and has a wide range of applications and strong modification ability. The material has good mechanical properties, its strength is 5~8 times of that of ordinary polyethylene, and has extremely high fatigue durability, good impact resistance, and good elasticity. Therefore, it has good indentation resistance, good abrasion resistance, and can maintain high rigidity especially at low temperature. UHMWPE can also form a non-lubricating surface, so it can be used in extremely compact sealing devices. In addition, its structure is also very stable, its oxygen content is reduced, and its corrosion resistance will also be enhanced.

The molecular weight of ultra-high molecular weight polyethylene (UHMWPE) is more than 30 times that of general polyethylene. The main component of UHMWPE is polyethylene. Its chain property is more stable than that of general polyethylene. The benzene number is higher. The molecular chain formed is larger than that of general polyethylene. Its tensile strength is extremely high, which can exceed 200000 psi, and the tensile strength is 6000-8000psi.

Ultra-high molecular polyethylene has been widely used in practice and has been widely concerned by the society. It is an important material in aerospace, automobile, sports and leisure, medical treatment, semiconductor and other fields, and has been applied in various fields. In the automobile industry, UHMWPE is often used to manufacture various parts; In the aerospace field, it can be used to manufacture various fuselage and cabin parts; In the field of sports and leisure, it can be used to manufacture sports equipment such as skiing, diving and water skiing; In the medical field, surgical implants are made of ultra-high molecular polyethylene and its related compounds; In the semiconductor industry, UHMWPE can be used to manufacture various shell parts for semiconductor packaging.
