Enhancing Polylactic Acid (PLA) with Aurorium Citroflex™

Polylactic acid (PLA) is a widely used biopolymer known for its biodegradability and bio-based origin. However, its inherent brittleness and limited thermal stability can be difficult to work with and may even limit its application range. To address these limitations, plasticizers are often incorporated to improve flexibility and processability. 


Citroflex™ Citric Acid Esters as Effective Biodegradable Plasticizers 

Aurorium's Citroflex™ series offers a range of citric acid esters that serve as effective plasticizers for PLA. These esters are derived from renewable resources, aligning with the sustainability goals of biopolymer applications. 

Key Benefits: 

 

Improved Flexibility: Incorporating Citroflex™ plasticizers enhances the elongation at break of PLA, making it more suitable for applications requiring flexibility. 
 

Enhanced Processability: The addition of Citroflex™ esters reduces the glass transition temperature (Tg) and melting point (Tm) of PLA, facilitating easier processing at lower temperatures. 

Sustainability: Being bio-based and biodegradable, Citroflex™ plasticizers contribute to the overall environmental friendliness of PLA-based products. 

Application Areas: 

The improved properties of PLA plasticized with Citroflex™ esters make it suitable for a variety of applications, including the following: 

Food Packaging Materials: Enhanced flexibility and clarity are beneficial for films and containers. 

Agricultural Films: Improved mechanical properties extend the usability in mulch films and other agricultural applications. 

Consumer Goods: Better durability and processability expand the potential for PLA in various consumer products. 


Aurorium's Citroflex™ enhances elongation, and reduces the glass transition temperature, playing a critical role in supporting the transition towards biodegradable plastic resins. Talk to a technical expert today about which Citroflex™ grade will work for your PLA application!
