Ecoflex A Completely Biodegradable Aliphatic-Aromatic Polyester. 104... [Pg.92]

Ecoflex ES was commercialized by BASE in 2010 as a compound with poly(lactic acid) (PEA) (Ecovio ES see Sect. 4.2.2). Ecoflex ES is an aliphatic-aromatic polyester with a similar structure to that of Ecoflex E (see Eig. 3). However, through exchanging one of the monomers with a monomer derived from plant oil, the new Ecoflex ES is partly based on renewable resources. [Pg.105]

Both Ecoflex and Ecovio are protected by various patents. The aliphatic-aromatic polyester PBAT is protected by its composition (EP-B 736557) and chain extension process (EP-B 792309, EP-B 809664, EP-B 809666, EP-B 1074570). [Pg.114]

The price of synthetic biodegradable polymers has come down a little during the last three years. In 2003, for example, the average price of Eastar Bio and BASF s Ecoflex was around 3.5-4.0 per kg. In 2005, the average cost of an aliphatic aromatic polyester biopolymer was between 2.75-3.65 per kg. The more specialised polymers, such as DuPont s Biomax, cost as much as 5-6 per kg. Polycaprolactones cost between 4-7 per kg. Synthetic biodegradable polymer prices are expected to fall further over time as production volumes increase and unit costs fall further. [Pg.89]

At the end of the 1990s, BASF commercialized Ecoflex F, a completely biodegradable statistical copolyester based on the fossil monomers 1,4-butanediol (BDO), adipic acid and terephthalic acid (see Fig. 3). Ecoflex F combines the good biodegradability known from aliphatic polyesters with the good mechanical properties of aromatic polyesters. [Pg.104]

BASF s Ecoflex and Novamont s Eastar Bio Ecoflex are aromatic-aliphatic co-polyesters based on butanediol, adipic acid, and terephthalic acid. BASF s products contain long-chain branching while Eastar Bio is highly linear in structure. [Pg.88]

With the attempt to combine good material properties of aromatic polyesters and biodegradability of aliphatic polyesters, aliphatic aromatic copolyesters have been developed during the last years to be used as technical biodegradable plastics The BASF AG / Germany is now producing a biodegradable material based on a copolyester of 1,4-butanediol, adipic acid and terephthalic acid (BTA-copolyester) tmder the trade name Ecoflex in a several thousand tons per year scale.

BASF has introduced their aliphatic-aromatic copolyesters (AAC) product under the name Ecoflex . This material is widely used to produce compostable packaging and films. According to the BASF s corporate website, annual production of Ecoflex has risen to 60,000 MT to keep up with the demand for biodegradable plastics, which is growing at a rate of 20% per year. At the same time, BASF also produces a blend of polyester and PLA — a product called Ecovio . This high-melt-strength polyester—PLA can be directly processed on conventionally blown film lines without the incorporation of additives. Moreover, Ecovio has extraordinary puncture-and tear-resistance and weldability. Another company, Eastman, has also produced AAC, with the tradename Eastar Bio . Eastar Bio has a highly linear structure, while Ecoflex contains... [Pg.12]

In contrast to most aliphatic polyesters, aromatic polyesters like PET provide excellent material properties [50]. To combine good material properties with biodegradability, aliphatic/aromatic copolyesters have been developed. Several major polyester producers in Europe and the United States have recently begun marketing aliphatic/aromatic copolyesters for biodegradable applications. BASF markets a product, Ecoflex , which is a copolyester of butanediol, adipic acid, and dimethyl terephthalate. Eastman s Eastar Bio Copolyester 14766 is a similar aliphatic/aromatic copolyester. DuPont markets a modified PET known as Biomax . [Pg.195]
