Poly Butylene Adipate-Co-Terephthalate Uses

Poly butylene adipate-co-terephthalate (PBAT) is a biodegradable polymer synthesized from petrochemical resources. PBAT has a very high elongation at break, which makes PBAT one of the most promising alternatives to LDPE packaging films. However, the applicability of PBAT films is still limited by low strength. In this work, we used polyethylene glycol 600 (PEG-600) as a coating agent to modify the surface of calcium carbonate. A series of PBAT/CaCO3 composite films with different CaCO3 particle sizes. The effects of particle size and capping agent content of CaCO3 filler on the mechanical.

1.4-Butanediol

图片
1.4-Butanediol (chemical formula: HOCH2CH2CH2CH2OH) is one of the isomers of butanediol, a terminal dihydroxy substituent of butane, which is a colorless, viscous liquid at room temperature. Industrially, BDO is produced by allowing acetylene to react with two molecules of formaldehyde to form BDO, which is then hydrogenated. BDO can also be obtained by gas-phase hydrogenation of anhydrides.

Tetrahydrofuran (THF) is a colorless, volatile liquid with the odor of ether or acetone and is miscible with water and most organic solvents. THF is highly flammable and may thermally decompose into carbon monoxide and carbon dioxide.
