PBAT (short for polybutylene adipate terephthalate) is a biodegradable random copolymer, specifically a copolyester of adipic acid, 1,4-butanediol and terephthalic acid. PBAT is produced by many different manufacturers and may be known by the brand names ecoflex , Wango, Ecoworld , Eastar Bio , and Origo-Bi .
The process results in the production of H 2 O and CO 2. Despite the release of CO 2 into the environment, biodegradable plastics leave a smaller footprint than petroleum-based plastics that accumulate in landfills and cause heavy pollution, which is why they are explored as alternatives to traditional plastics.
Polybutylene terephthalate (PBT) is a thermoplastic engineering polymer that is used as an insulator in the electrical and electronics industries. [2] It is a thermoplastic (semi-)crystalline polymer , and a type of polyester .
Polyethylene terephthalate (PET) is a common condensation polymer.. In polymer chemistry, condensation polymers are any kind of polymers whose process of polymerization involves a condensation reaction (i.e. a small molecule, such as water or methanol, is produced as a byproduct).
Poly(ethylene adipate) or PEA is an aliphatic polyester. [3] It is most commonly synthesized from a polycondensation reaction between ethylene glycol and adipic acid . [ 4 ] PEA has been studied as it is biodegradable through a variety of mechanisms and also fairly inexpensive compared to other polymers. [ 5 ]
Bis(2-ethylhexyl) adipate or DEHA or DOA is an organic compound with the formula (CH 2 CH 2 CO 2 C 8 H 17) 2. It is the diester of 2-ethylhexanol and adipic acid. It is a colorless oily liquid. DEHA is sometimes called "dioctyl adipate", incorrectly. Another name is di(2-ethylhexyl) adipate.
Bis(2-ethylhexyl) terephthalate commonly abbreviated DEHT (Dioctyl terephthalate or DOTP), is an organic compound with the formula C 6 H 4 (CO 2 C 8 H 17) 2. It is a non- phthalate plasticizer , being the diester of terephthalic acid and the branched-chain 2-ethylhexanol , which is often generically referred to as octyl.
Acrylic elastomer is a general term for a type of synthetic rubber whose primary component is acrylic acid alkyl ester (ethyl or butyl ester). [3] Acrylic elastomer possesses characteristics of heat and oil resistance, with the ability to withstand temperatures of 170–180 °C.
