Universal laminate


Universal laminates are made in a range of different thicknesses. The laminates have been 1.6 mm thick for many years. With the improvement of production methods and decorative paper opacity, it has turned to the production of thinner laminates. The most common laminates currently have a thickness of 1.25 mm. The reduction in thickness is due to the use of lower amounts of decorative paper and overlay paper and a reduction in the total basis weight of the core paper.
Laminates for facades: When plastic laminates are used to cover upright surfaces, they are not subject to the same degree of wear as horizontal surfaces. Therefore they generally do not contain overlay paper and tend to use a thinner core paper layer. This makes the facade laminate thinner than that used for horizontal surfaces, with a typical thickness of 0.6 mm.
Although reducing the thickness of the laminate, it is economical because it requires less material per unit area, but it exacerbates other problems. Among them, it is mainly difficult to handle large (1.5 mx 3.7 m) laminates. Since the thickness of the laminate is reduced, the cracking condition is increased during processing.
In the manufacture of thinner laminates, the phenolic resin layer generally has a greater degree of thinning than the melamine layer. In view of the dimensional stability of the phenolic layer over the melamine layer when the humidity is deuterated, the total panel becomes less stable. . According to the National Electrical Manufacturers Association (NEMA) standards, 1.25mm thick laminates are required to fluctuate laterally by no more than 0.9%, but for 0.6 mm thick laminates are allowed to fluctuate below 1.2%. As a consequence, many problems such as warpage and stress cracking will occur.
