▶Adipic acid

124-04-9

Adipic acid (CAS: 124-04-9), also known as hexanedioic acid, is a white crystalline powder widely used in the production of nylon, polyurethanes, and other polymers. It serves as a key component in the manufacturing of various products, including automotive parts, textiles, coatings, and adhesives. Adipic acid is valued for its ability to enhance the durability, flexibility, and heat resistance of materials.

▶Toluene Diisocyanate(TDI)

584-84-9

TDI(toluene diisocyanate) is a commonly used polyisocyanate, which is a polyurethane (PU)material and an important basic raw material. TDI is a mixture of two isomers, 2,4-TDI and2,6-TDI, commonly used in the polyurethane industry, including three common grades :TDI-80/20,TDI-100 and TDI-65/35. The preceding numbers indicate the amount of 2, 4-TDI in the composition.
For example, 80 in TDI-80/20 means 2, 4-TDI (80%) and 2, 6-TDI (20%). The 100 in TDI-100 is basically 2, 4-TDI(about 98%), with very few isomers of 2, 6-TDI. Mainly used in the production of soft polyurethane foam and polyurethane elastomers, coatings, adhesives and so on.

▶Methylene Diphenyl Diisocyanate(MDI)

101-68-8

MDI is a polyurethane material synthesized by isocyanate, polyol and its auxiliary agent. With its excellent properties, various varieties and broad uses, MDI is unique among many synthetic materials and has become one of the fastest developing materials today. As the main raw material for the synthesis of polyurethane, isocyanate.

▶Butanediol(BDO)

110-63-4

1, 4-butane-1,4-diol is an organic compound with a molecular formula of C4H10O2 and a molecular weight of 90.12. The appearance is colorless or light yellow oily liquid. Combustible, freezing point 20.1℃, refractive index 1.4461. Soluble in methanol, ethanol, acetone, slightly soluble in ether. Hygroscopic, bitter taste, slightly sweet mouth.

▶1, 3-Butylene Glycol

107-88-0

1,3-Butanediol glycol is a colorless transparent liquid.
It can be used as a humectant, antibacterial agent, and solvent in cosmetics and it is applied to cosmetic water, cream, lotion, gel, toothpaste, and other products;

▶Tetrahydrofura (THF)

109-99-9

Tetrahydrofuran (THF), or oxolane, is an organic compound with the formula (CH2)4O. The compound is classified as heterocyclic compound, specifically a cyclic ether. It is a colorless, water-miscible organic liquid with low viscosity. It is mainly used as a precursor to polymers. Being polar and having a wide liquid range, THF is a versatile solvent.

▶Polyether polyol(PPG)

9003-11-6 

Ether polyol (referred to as polyether) is composed of initiator (compound containing active hydrogen group) and ethylene oxide (EO), propylene oxide (PO), butylene oxide (BO), etc. in the presence of a catalyst Prepared by polyaddition reaction. The one with the largest polyether yield is glycerol (glycerol) as the initiator and epoxy (generally PO and EO are used together), by changing the feeding method of PO and EO (mixed or separately added), the addition ratio, Various general polyether polyols can be produced under conditions such as the order of addition.

▶Polymer polyol

75-13-8

Polymer polyols are polyethers based on general polyether polyols, which are polymerized by adding acrylonitrile, styrene and other vinyl monomers and initiators. Mainly used in soft bubble field. Polyether polyols are mainly made of propylene oxide as raw materials, and are grafted to sucrose, glycerol, diethylene glycol and other polyols, which are mainly used in soft bubbles, hard bubbles, adhesives and so on.
