Our Technology 


Ecorntech CB Korea’s parent company Ecorntech Inc. (USA), in conjunction with the U.S. Department of Agriculture’s Forest Products Laboratory, developed our patented proprietary Supercritical Carbon Dioxide Foaming Technology. The technology ‘blasts’ the compound mixture of wood powder (or cornstalk fiber) and polypropylene during the extrusion process, which creates a fibrous core that is unique to ecornboards™. This gives our products a unique advantage of achieving premium density while maintaining competitive prices.


Ecornboards™ combines the attractive qualities of both wood and plastic, providing exceptional resistance to decay, discoloration and deformations from prolonged exposure to natural elements. Simultaneously, it is able to maintain wood-like textures and aesthetics, providing environmentally friendly, enhanced substitutes to natural wood products at more competitive price levels.
