Wanhua Hexiang board has excellent flame retardancy, can be used in the environment below 50℃ to 100℃, and will not produce other adverse chemical reactions, and will not burn when it meets open flames, so it has become a common material in public places.

Wanhua Hexiang board has a porous structure inside, which can absorb noise and heat well and has good sound and heat insulation effects. Wanhua Hexiang board is also excellent in waterproof performance, its water absorption expansion rate is only 5%, and it can maintain its own stability when wet with water without decomposition reaction.

The biggest feature of Wanhua Hexiang board is that it does not contain formaldehyde, because it is made of straw and ecological glue. Tested by national authorities, its formaldehyde emission is zero, which can be said to be the most environmentally friendly wood-based panel at present.

The Core Technology of Wanhua Hexiang Board

Replacing urea-formaldehyde resin with special ecological adhesive for modified MDI straw by Wanhua is the core technology of Wanhua Hexiang board that does not release formaldehyde, and it is also the key to distinguish it from other ordinary boards.

The MDI used in Wanhua Hexiang Board is a special modified MDI ecological adhesive developed by Wanhua Research Institute according to the characteristics of straw components. Brown to dark brown liquid at room temperature. On the basis of PMDI (polymeric MDI), it reacts with biomass extract to improve the molecular structure of PMDI and its affinity with straw fiber.

It has the characteristics of high reactivity, strong wettability and strong chemical bond strength, which can overcome the characteristics of waxy layer, low surface free energy and high ash content of straw and form a solid whole with straw fiber.
