Uses of Poly Butylene Adipate-co-terephthalate

图片
Poly butylene adipate-co-terephthalate (PBAT), also known as polybutylene glycol butyrate, is a semi-aromatic, biodegradable thermoplastic copolyester that can be easily molded and thermoformed. PBAT is a random copolymerization of 1,4-butanediol and dimethyl terephthalate (DMT) monomers.

Uses of Tetrahydrofuran

图片
Tetrahydrofuran is a colorless and transparent liquid with an ether-like odor. Tetrahydrofuran can be miscible with water. The azeotropic mixture with water can dissolve cellulose acetate and alkaloids such as caffeine, and the dissolution performance is better than that of THF alone.

1-methyl-2-pyrrolidone (NMP)

NMP, also known as 1-methyl-2-pyrrolidone or N-Methylpyrrolidone, is a solvent used in a range of products. The average consumer is most likely to encounter NMP in paint strippers, although safer alternatives exist. NMP has been strongly associated with developmental effects, including abortion.

Polytetramethylene Ether Glycol (PTMEG)

图片
Polytetramethylene ether glycol (PTMEG) is a waxy, white solid that melts to a clear, colorless, viscous liquid near room temperature. The main applications of PTMEG are the production of spandex (polyurethane) fibers, polyurethane elastomers, and copolyester-ether elastomers. PTMEG is produced by the catalytic polymerization of tetrahydrofuran (THF).

Uses of 1.4-Butanediol

图片
What is the uses of 1.4-Butanediol ? 1,4-Butanediol  is an organic substance with the molecular formula C4H10O2 and molecular weight 90.12. Appearance is colorless or light yellow oily liquid. Flammable, freezing point 20.1℃, refractive index 1.4461. soluble in methanol, ethanol, acetone, slightly soluble in ether. 1.4-Butanediol is hygroscopic, bitter in odor and slightly sweet in mouth.

Poly Butylene Adipate-Co-Terephthalate (PBAT)

Poly butylene adipate-co-terephthalate (PBAT) is a plastic produced from 1,4 butanediol, dimethyl terephthalate and adipic acid. PBAT is transparent, biodegradable and compostable, and can be used in extrusion and injection molding processes. Globally, PBAT has a range of applications such as laminated bags, garbage bags, mulch films, cling films, stabilizers, etc., with final use in packaging, agriculture and fisheries, consumer products, coatings and other industries.

PBAT (Poly butylene adipate-co-terephthalate)

PBAT has excellent mechanical performance, almost same as PP and ABS. Good heat resistance and outstanding process ability allows PBAT to be variously processed on conventional blown film plants. Poly butylene adipate-co-terephthalate is the best biodegradable plastic in terms of process ability in current market. PBAT can be blended with a great quantity of calcium carbonate and starch etc. to produce cost effective products. Such as Shopping bags, mulching films, paper coating, labels, other packaging materials.

Tetrahydrofuran (THF)

图片
Tetrahydrofuran (THF) is a colorless, transparent organic compound with an ether-like odor and the chemical formula (CH2)4O. Tetrahydrofuran is used primarily as a precursor for polymers, including for surface coatings, adhesives and printing inks. Tetrahydrofuran is miscible with water and has a low viscosity, making THF a versatile solvent for use in a variety of industries.

N-Methylpyrrolidone (NMP)

First, N-methylpyrrolidone is a very slow evaporating solvent. NMP has a boiling point of 202°C. A thin film of NMP requires over 15,000 s for 90% evaporation at room temperature. (See the solvent properties in Table 6.2 at the end of this chapter.) If this is the only solvent used in PAI- or PES-based coatings, viscosity does not build up rapidly after the application and the coating will be prone to running, dripping, and sagging. The most effective fast-evaporating solvent for these resins is DMF, but that solvent has serious safety issues.

PTMEG (Polytetramethylene Ether Glycol)
