Hard Board ProcessHardboard by Green fiber is produced by the wood chips are pulverized into wood fibers through the process of forming a sheet with water then compressed by heat and high pressure. It's also formaldehyde free due to the processing without any glue-resin.
“Green Fiber” We are Thailand’s largest manufacturer of hardboard. Green Fiber hard board is a natural product that provides very high strength and free of formaldehyde. In hardboard manufacturing process, the wood chips are pulverized into wood fibers, is formed in wet forming machine.
The fiber mat is compressed with press rolls while applying heat treatment. No added synthetic adhesive to bind the fibers obtain formaldehyde – free product.
