Many people are still not aware of the differences between high pressure laminates and the low counterparts. The differentiation is not just about evaluating the advantages and disadvantages. The manufacturing process that goes into developing these products also differs a lot. Both products have their own pros and cons. Here we will focus on how these products are manufactured and which product scores brownie points over the other. There is a myth that melamine is only used in contriving HPL, however it is not true. Melamine as a chemical is used for manufacturing both the products. It is the actual process of manufacture that distinguishes these products. Well, these technical points would sound like a science lecture to some. So, I will rather keep it simple. Let us discuss about melamine as a chemical. It is an organic white powder derived from the process of heating cyanide. It has been termed safe by various authorities and has been around for decades now.
The other pivotal materials used for developing these high pressure laminates and LPL include impregnating layers of Kraft paper. It can be defined as a cardboard or firm paper. The paper is generally impregnated with melamine resins to create a laminate. After that, the product is merged with a decorative film layer. The final straw is to attach it to a wooden substrate. The bases widely used include fiberboard or particle boards. Thus, the final product is on the table for use. These products are widely used for designing furniture, walls, floors, countertops, kitchen tops and much more.
Now let's discuss about the process of infusion. This is the process that differentiates High pressure laminates and the low pressure counterparts.
HPL: The layer is manufactured under pressures of 70 to 100 bars and temperatures of 270 to 320 degrees Fahrenheit using adhesives. On the other hand LPL is developed under pressures of 20 to 30 bars and temperatures of 330 to 375 Fahrenheit with no adhesives. Now let us discuss the advantages and disadvantages of the product. The main difference between the two products is the price. LPL is available for much cheaper prices than HPL. Both serve as a good option for hygienic preferences and usage in kitchen areas and medical offices. On the other hand, high pressure products score high on durability as compared to LPL. Both are excellent choices, but LPL is widely used for decor purposes.
