Chipboard – wood chipboard – consists of wood waste, which is ecuador mobile database and glued together by high-temperature pressing with the addition of binding resins (phenolic and formaldehyde), which include sawdust, large shavings, etc. On the outside, these pressed sawdust can be covered with decorative layers: laminate, melamine, veneer.
Grade 1 board is made from selected sawdust, usually of one type of wood. Its surface is perfectly smooth, without chips. On both sides, the board is decorated by applying a laminated film or veneer.
Grade 2 is characterized by minor defects on the surface in the form of chips and scratches. It can be either with or without cladding.
Grade 3 – these are boards with significant defects on the surface. They do not require cladding and are used only for auxiliary construction purposes.
Chipboard is afraid of water. Therefore, under conditions of high and constant humidity, the chipboard will begin to crumble.
It is also worth noting the fragility of such a plate. Chipboard does not tolerate fine processing well, it is difficult to make shaped parts from it.

LDSP is an abbreviated name for laminated chipboard, the surface of which is treated with a special film based on thermosetting polymers (this is a type of paper-resin film). I think everyone has seen laminated paper. The board is laminated in the same way. Only the board is thicker than paper, and its ends remain open.
Often such a board is simply called "laminate". This applies to the name of a popular floor covering, and to furniture "made of laminate". However, laminated chipboard and laminate are not the same thing, they are two different coatings.

Laminated chipboard is divided into several groups:
