Polybutylene adipate terephthalate (PBAT)
PBAT
ADVANTAGES AND PROPERTIES OF PBAT:
Biodegradability:
PBAT is considered an environmentally friendly polymer as it is biodegradable and compostable under suitable conditions. It can be decomposed in industrial composting plants, breaking down into natural compounds such as water, carbon dioxide and biomass.
Flexibility and elasticity:
PBAT exhibits good flexibility and elasticity, making it suitable for applications that require stretchability and impact resistance.
Transparency and gloss:
PBAT has a similar transparency and gloss to conventional plastics e.g. polyethylene (PE) or polypropylene (PP). This property enables applications where transparency is desired, such as packaging.
Good processability:
PBAT can be processed using standard plastics processing methods, including extrusion, injection molding and blow molding. It can be produced in various forms, including films, sheets, fibers and thermoformed products.
Compatibility with other polymers:
PBAT can be blended or coextruded with other polymers to modify its properties. For example, blending PBAT with other biodegradable polymers or additives can improve biodegradability or customize performance for specific applications.
CHEMICAL REGULATIONS:
Raw materials are REACH registered.
APPLICATIONS:
Packaging:
PBAT is often used for flexible packaging applications such as films, bags and pouches. Due to its good flexibility, transparency and sealability, it is suitable for various food packaging, compostable bags and agricultural films.
Disposable products:
PBAT is used in the production of disposable items such as cutlery, straws, cups and food containers. These items can be biodegradable and serve as an alternative to conventional single-use plastics.
Agriculture:
PBAT films are used in agriculture for mulch films, greenhouse covers and biodegradable soil applications. These films help regulate soil temperature, retain moisture and reduce the need for synthetic pesticides.
Hygiene products:
PBAT is used in the production of biodegradable hygiene products such as diapers, sanitary napkins and wet wipes.
Other applications:
PBAT has potential for other applications, including textiles, medical devices, adhesives and 3D printing.
PBAT is a promising biodegradable and compostable copolymer that can help reduce the environmental impact of plastic waste. Its versatile properties, miscibility with other polymers and compatibility with existing processing techniques make it suitable for a range of applications, offering a more sustainable alternative to conventional plastics.
