Modified starch can be used as a binder in the production of MDF (Medium Density Fiberboard). MDF is a material made by pressing wood powders, fibers and binders. Among these binders, urea-formaldehyde resin is often used, but due to environmental concerns, alternative binders are being investigated.
Modified starch is seen as an alternative to urea-formaldehyde resins. Modified starch can be used in MDF production due to its water absorbency, viscosity, gel formation, stability and adhesive properties. In addition, the use of modified starch can reduce the release of formaldehyde in MDF production, so that a more environmentally friendly product can be obtained.
Some properties that modified starch can provide in MDF production:
1 – Reducing water absorbency: The use of modified starch can reduce the water absorbency of MDF and thus a more durable product can be obtained.
2 – Lower formaldehyde release: Modified starch can contribute to a more environmentally friendly MDF production by reducing formaldehyde release.
3 – Adhesion properties: Modified starch can provide high adhesion properties to MDF, thereby increasing the durability of the product.
4 – Lower production costs: Modified starch can be less costly than other binders, thus reducing costs in MDF production.
5 – Improved processing properties: The use of modified starch can improve the processing properties of MDF and allow manufacturers to shape and cut more easily.
For these reasons, modified starch is considered an important alternative binder in MDF production.
