- What is PBAT made of?
PBAT (short for polybutylene adipate terephthalate) is a biodegradable random copolymer, specifically a copolyester of adipic acid, 1,4-butanediol and terephthalic acid (from dimethyl terephthalate).
- Is PBAT compostable?
PBAT is a certified 100% compostable material, which leaves no pollution to the environment at all after quick degradation in composting facilities. Click here to check the article issued in Bioplastics magazine for reference.
- What is the pros&cons of PBAT properties?
- Wide melting point
- Low elastic modulus and stiffness
- High flexibility and toughness
- Ideal for blending with other biodegradable polymers
- Not strong and rigid enough for many plastic processing methods
- What is the application of PBAT?
PBAT is a perfect raw material for making compostable bags and film. Such as shopping bags, kitchen waste bags, dog waste bags, agriculture mulch film,…
- What is the difference between PBAT & PLA?
Even though PBAT and PLA are both 100% compostable and biodegradable. They are two different bio material.
- Source: PLA comes from lactic. PBAT is a copolymer with three different monomers.
- Application aspect: PBAT is used in blow film more often while PLA is more suitable for extrusion/injection/thermoforming/… grade application.
- Properties: PBAT is soft and flexible with low elastic modules, PLA is hard and rigid.
