Ecoboard
Description
Ecoboard is a brand name for a solid construction board made from cellulose fibers derived from straw and a water-based slurry of methylene diphenyl diisocyanate (MDI) adhesive. Ecoboard is manufactured for 100% wheat straw and does not emit any of the organics acids found in other MDF boards. The strawboard has strength comparable to other MDF boards for weight bearing and resisting deformation. A wax coating on the surface of Ecoboard acts as a waterproof coating and sealant. Additionally the MDI/straw connection forms a hydrophobic barrier. No fire-retardants are added to Ecoboard since its high CO2 content inhibits flame production.
Synonyms and Related Terms
Strawboard; Wheatboard
Applications
Used as a structural material for pedestals, display decks, display panels and risers.
Personal Risks
MDI is the least hazardous of the commonly available isocyanates, but it may act as an allergen and sensitizer.. Personal protective equipment is recommended.
