Overview of product
A new phenolic resin by using non-edible biomass which has comparable high strength and heat Resistance to oil-based phenol resinsThe product is produced by using Lignin which is non-edible biomass. Lignin modified resin shows comparable workability and performance to conventional oil-based phenol resins. Furthermore the resin shows unique property in specific application. |
- *1: This development utilizes results obtained from a project commissioned by the New Energy and Industrial Technology Development Organization (NEDO).
