GOST 10632-89 / chipboard
Chipboard (Chipboard) – sheet material made by hot flat pressing of wood particles mixed with a binder.
For the manufacture of chipboard used low-toxic urea-formaldehyde and phenol-formaldehyde binders.
Chipboards are brought to nominal sizes by grinding. The quality of chipboard is assessed according to the following indicators: static bending strength, tensile strength perpendicular to the surface of the plate, thickness swelling, humidity, density, surface roughness of the plates, formaldehyde content, specific resistance of the screw pulling out, defects.
According to its characteristics, chipboard is suitable for surface cladding with both veneer and paper-resin film.
