Today's KNOWLEDGE Share

When trying to move to plant-based or biosourced plastic materials, a whole host of challenges will come-up.


Due to intrinsically lower Tg of bio-materials, chances are that you will have to transition to semi-crystalline materials and develop a very skillful mastering of precise shrinkage control in your molding process. Subtle physical phenomena including molecular orientation, flow induced crystallinity, slow dimensional recovery by relaxation will make your life a bit more complicated.


Lower thermal stability will also seriously tighten-up your limits in terms of thermal control and residence time in your process. Drying may suddenly become a critical step too.

Overall, a much better and deeper understanding of the molding process and specific plastic materials will be needed to address these challenges.

Today's KNOWLEDGE Share:PLA BOTTLE

-
Image
Today's KNOWLEDGE Share Ever wondered how we can reduce plastic pollution in India? The Mysuru-based Defence Food Research Laboratory (DFRL), affiliated with the DRDO, has launched an eco-friendly remedy with the introduction of biodegradable water bottles. Crafted from sustainable Polylactic acid (PLA) material, these bottles not only combat plastic waste but also contribute to reducing the overall carbon footprint. The best thing about this bottle is its all-encompassing sustainability approach – the bottle, cap, and label are all compostable. This innovation, derived from 100% bio-based and renewable sources, sets us on a path towards environmental conservation and fosters a greener and more sustainable future.
