The Central Salt and Marine Chemical Research Institute (CSMCRI) has developed bio-derived furanic polymers (BFP) developed that has better UV-shielding efficiency than many commercial compounds. 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.
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 diameter 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. As BFP is biomass derived polymeric powder which 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.
The most important advantages are; the replacing of the petroleum-derived products with biomass-derived products is an emerging area, the use of a biomass-derived polymer as a UV-shielding agent with higher efficiency than petro-derived commercial polymers would be highly beneficial. Additionally, the bio-derived furanic polymers (BFP) developed at CSIR-CSMCRI has better UV-shielding efficiency than many commercial compounds. It improves the mechanical strength of its composite materials. Further, it can be blended with many natural bio-polymers and their derivatives to make completely bio-based bio-degradable films/products. This technology is at the TRL of 4.
