Title of Process/ Know-how/ Product/Design/Equipment
UV shielding bio-derived furanic polymers.
Application/Uses/Problem being addressed
Application potential: The humin-like furanic polymers can be used as both UV light shielding agent and as well as for improving mechanical strength in various products such as thin films, bottles, tablet strips for pharmaceutical uses, windows, display screens guard, sun protective glass, welding glass, vertical blind, cloths, paints, varnish, dispersant, sun-screen lotions and creams.
Salient Technical Features including Competing Features/ Impact
TRL Level & Scale of Development:
Furanic polymer (BFP) has been prepared at 300 g per batch, and BFP/PVA composite thin film is prepared at 1-meter length scale by a solvent casting method. BFP/PMMA composites prepared at 2.5 cm dia scale by micro compounding and compressing mould-casting method. BFP/LLDPE composite is prepared at few hundred meter scale by melt blowing method. The approaches render confidence that the BFP can be used at even larger scale through different methods.
Business scope & opportunity (in terms of scale, cost, market etc.):
As BFP is biomass derived polymeric powder, it can be used as both UV shielding agent and as well as for improving mechanical strength in various products such as thin films, bottles, tablet strips for pharmaceutical uses, windows, display screens guard, sun protective glass, welding glass, vertical blind, cloths, paints, varnish, dispersant, sun-screen lotions and creams.
Environmental Considerations:
This process is eco-friendly. No waste is generated.
