Ecoflex F, the original Ecoflex grade, is a completely fossil-based ahphatic-aromatic copolyester produced by BASF (see Sect. 4). It is synthesized from 1,4-butanediol, adipic acid and terephthalic acid, and is a poly(butylene adipate-co-butylene terephthalate) (PBAT). [Pg.95]

Figure 9.4 and Table 9.1 respectively show the chemical structure and the properties of these materials. Most commonly used is poly(butylene adipate-co-terephtalate) (PBAT). BASF, DuPont and Zhejiang Hangzhou Xinfu (China) manufacture and market these aromatic polyesters, under the respective brands Ecoflex , Biomax and Biocosafe . Biomax has a high terephthalic acid content, which modifies some of its properties such as the melting temperature (200°C). According to Muller et al., an increase in terephthalic acid content tends to decrease the rate of biodegradation into compost [MUL 97]. [Pg.171]

PLA/poly(butyleneadipate-co-terephthalate) (PBAT) blends can be prepared with varying tetrabutyltitanate (TBT) through melt-extrusion [33]. A twin-screw extruder was used to obtain the blend. Mechanical properties, such as tensile strength, elongation at break, toughness, and stiflhess of PLA/PBAT blends can be improved significantly by the incorporation of TBT [33]. [Pg.326]

Sis et al. prepared composites based on poly (lactic acid) (PLA)/poly (butylene adi-pate-co-terephthalate) (PBAT)/kenaf fiber using a melt blending method [39]. A PLA/ PBAT blend with the ratio of 90 10 wt%, and the same blend ratio reinforced with various amounts of kenaf fiber were prepared and characterized. The addition of kenaf fiber reduced the mechanical properties sharply due to the poor interaction between the fiber and polymer matrix. Modification of the composite by (3-aminopropyl)tri-methoxysilane (APTMS) showed improvements in mechanical properties, increasing up to 42.5, 62.7 and 22.0% for tensile strength, flexural strength and impact strength, respectively. The composite treated with 2% APTMS successfully exhibited optimum... [Pg.23]

To improve processability, mechanical properties and moisture resistance while maintaining biodegradability, starch may be mixed with aliphatic or aliphatic-aromatic polyesters, such as polycaprolactone (PCL), polylactic acid (PLA) and poly(butylene adipate-co-terephthalate) (PBAT), suffering complexing with these pol)miers [33,35]. [Pg.14]

Poly(butylene adipate-co-terephthalate) (PBAT) Some of its main applications are films (mulch, containers, bags), filaments, thermoformed and injection moulded products, and blown bottles. Two products in the market are Ecoflex (BASF, 14,000 t per year) and MaterBi (former EasterBio/Eastman, now Novamont, 15,0001 per year). For some applications, PBAT has a very low stiffness, and may be mixed with PITB or PEA, for example. It may also be mixed with thermoplastic starch [69, 71]. [Pg.25]

Xiao et al prepared blends of PLA with poly(butylene adipate-co-terephthalate) (PBAT), and followed their isothermal crystallization. They showed that the Avrami exponent was almost unchanged. However, the crystallization rate increased with the PBAT content. [Pg.83]

Poly(butylene adipate-co-terephthalate) (PBAT), poly(butylene succinate) (PBS) or poly(ethylene succinate) (PES) are flexible biodegradable polyesters that have also been considered for blending with PLA. PBAT and PLA are immiscible polymers where PBAT phase formed small droplets in the PLA matrix. Drastic increase of elongation at break was observed (200% with only 5 wt% of PBAT) due to interfacial debonding mechanisms as the interfacial adhesion between the two polymers was low. The impact...

Polyesters, poly(butylene succinate adipate) (PBSA), pofy(butylene succinate) (PBS), poly(ethylene succinate) (PES), pofy(butylene succinate)/poly(capiolactone) blend and poly(butylene adipate terephthalate) (PBAT) were evaluated about their enzymatic degradation by lipases and chemical degradation in sodium hydroxide solution [81]. In enzymatic degradation, PBSA was the most degradable by lipase PS from Pseudomonas sp. on the other hand PBAT containing aromatic ring was little degraded by 11 kinds of lipases. [Pg.145]

Poly (butylene adipate-co-terephthalate) (PBAT) is an interesting polymer [116,117] and has attracted more attention. PBAT is also a biodegradable poljmier, which has proper viscosity and elasticity. Moreover, the balance of biodegradability (e.g., life time) and its physical properties (e.g., thermal and mechanical properties) can be adjusted by controlling the molar ratio of comonomers in the copolymer [118,119]. It has been reported that the aliphatic/aromatic copolyester with aromatic units within the range of 35 - 55 mol% offers an optimal compromise of its biodegradability and physical properties.

The majority of petroleum-based compostable plastics belong to the polyester family, including Ecoflex , polycaprolactone (PCL), Ecovio , poly-butyrate adipate terephthalate (PBAT), and aliphatic copolyesters (The Impacts of Degradable Plastic Bags in Australia 2003). Table 4.14 lists several commercially available biodegradable or compostable plastic products. [Pg.92]
