FAQ: Biopolymers
Global bioplastic production capacity is expected to increase to 4.8 billion lb by 2024, driven by OEMs and brand owners steadily converting applications to these “green” materials. If you’re looking to supply compounds to meet this demand, here are some key processing considerations you need to know:
1. Buy flexible extruders
2. Remember that biopolymers are typically hygroscopic
3. Consider that biopolymers are shear- and pressure-sensitive
4. Biopolymers degrade rapidly, making purging important
