Tween 20, 40, 60 and 80. Polysorbates are derived from ethoxylated sorbitan (a derivative of sorbitol) esterified with fatty acids and exist as oily liquids. They are used in cosmetics to solubilize essential oils into water-based products, pharmaceuticals, detergents, paints, and plastic applications.
Polysorbate 80 USP/NF is a hydrophilic nonionic surfactant used as an emulsifier or surfactant in foods, medicines, skincare products, vaccines etc. It also acts as a surfactant in soaps and cosmetics.USP NF is a combination of two compendia, the United States Pharmacopeia (USP) and the National Formulary (NF).

Polysorbate 20 USP/NF is a polysorbate-type nonionic surfactant used in many commercial and household products. It is composed of 20 repeated units of polyethylene glycol via ethoxylation. Polysorbate 20 USP/NF is a wetting agent, as well as washing agent, stabilizer and solubilizer in food products, laboratory assays and industrial applications. It is also an excipient that stabilizes emulsions and suspensions and lubricant in ophthalmic solutions. Polysorbate 20 USP/NF is used by philatelists to remove stamps from envelopes and to remove residues from stamps, without harming the stamp itself. Polysorbate 20 USP/NF is also used as wetting agent in rubber balers in the elastomer industry. Polysorbate 20 has been used as a shape directing agent to synthesize spheroidal magnetite nanoassemblies.
USPâ??NF is a combination of two compendia, the United States Pharmacopeia (USP) and the National Formulary (NF).

Toluene diisocyanate (TDI) is an aromatic diisocyanate that is a clear, pale yellow liquid with a sharp, pungent odor, which is insoluble in water and miscible with most common organic solvents. TDI (CAS No. 26471-62-5) consists of two isomers: toluene-2,4-diisocyanate (2,4-TDI) (CAS No. 584- 84-9) and toluene-2,6-diisocyanate (2,6-TDI) (CAS No. 91- 08-7), which is commercially produced in different ratios. The most common ratio is 80% 2,4-TDI/20% 2,6 TDI. TDI is widely used and accounted for 34% of the global isocyanate market in 2000
Tdi 80/20 is used for Flexible Polyurethane Foam and other other polyurethane applications including elastomers,synthetic leather,coated fabrics,paints and adhesives.
It is spray-applied,closed-cell polyurethane foam system with high fire resistance properties.it applies to all kinds of spray-applied thermal insulation engineering,such as building exterior cold rooms,large-scale pipeline,etc.
