Bioplastics
Lignin Filler — Lignin, Filler Grade S
Lignin Filler S is a complex polymer extracted from plant cell walls, primarily from wood pulping byproduct. It can be used as a bio-based filler in thermoplastics and thermosets to reduce cost and improve properties like stiffness and UV resistance. Emerging applications also use it as a monomer for new bioplastics.
