Amorphous PHA and PLA blends for sustainable biopolymer applications

Overview

This innovative blend combines amorphous PHA and PLA polymers to create a sustainable biopolymer with enhanced biodegradability and flexibility. By leveraging the mechanical strength and processability of PLA and the flexibility and biodegradability of amorphous PHA, this material is designed to meet compostability standards. The inclusion of bio-based foaming agents or lightweight natural fillers reduces density without compromising performance, making it ideal for industrial applications that require compostable and low-density materials.

Technical specifications

• Base polymers: Amorphous PHA and PLA
• Additives: Biodegradable plasticizers, compatibilizers, lightweight fillers, and bio-based foaming agents
• Processing method: Standard injection molding with optimized parameters
• Features:
  • Improved interfacial adhesion for uniform morphology
