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.

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.

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) 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).

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) 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 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.
