For beginner)HPL Plywood knowledge& Manufacturing Experience Part 2 :HPL sheets(PLastic ) Colors/FINISHES and Select the manufacturers

There are many Chinese HPL sheets and compact manufacturers in China,most of the famous production regions such as Changzhou city ,Henan ,Linyi ,yantai ,zhenjian ,Hangzhou ….One of the famous HPL brand name is MADE IN USA Wilsonart®  .

How to select these suppliers and what types of HPL will be used for your HPL Plywood?We know that the MOST important and biggest HPL PLYWOOD importers are from the Israel and USA .

These HPL sheets manufacturers have different color and finishes for their HPL production design according to the market and their own innovation .

Different markets have different finishes ,the manufacturers should be careful about this ,the most easy and important way is send samples to the buyer to confirm ,keep an file and keep the samples always for one year ,if too long,sometimes the HPL sheets color will be fade and changed according to the surrounding condition if the quality of the HPL sheets is not good .Special projects deserve special laminates. Most of the  innovation team has created a growing range of specialty surface solutions to give you even more choice than ever.

The choice of surface finish is just as important to the functionality of the laminate as it is to the aesthetics. Sleek high gloss finish, highly resistant to scuffs and mar abrasions,luxury finish across a variety of colours and patterns. ,achieves the effect of wood pores just freshly treated.A rich complex surface finish that mimics wire brushed soft woods. A distinctive texture that is versatile on both woods and plain colours. Alternating glossy and matt areas are visually pleasing and a tactile surprise: the surface feels inherently natural, yet with a velvet smoothness.finish brings a natural tone and simplicity to spaces.Directional finish used on certain Woodgrain designs. The texture direction runs parallel to the ‘grain’ of the wood.Provides a near natural woodgrain look with an elegant matt finish. Suitable for vertical and light duty applicatio texture was inspired by crisp satin silk weaves with their subtle reflective and tactile quality. This small scale, versatile surface finish impresses with its textile feel, crisp touch and low gloss sheen.a smooth, linear woodgrain texture. A timeless yet unique interpretation of a lightly brushed, natural timber. Pure grain is subtle to the touch with a medium gloss level.Subtle surface detail highlighted by a soft polished sheen gives an authentic look of natural materials.

Even from the same factory,sometimes different shipments have different colors and finishes ,just make sure to test and see and compare the samples .Good HPL sheets manufacturers have good management ,they normally check daily prduction ,that is one of the guarantee.
After selecting the exact HPL sheets manufacturers ,confirming the Samples and TYPE and COLOR/FINISH NUMBER,then started to delivery the HPL to the plywood factory .
TELL the HPL sheets manufacturers,these sheetsa re used for laminating the PLYwood ,as the HPL sheets have both sides and ONE SIDE only used for laminating .If two sides ,this is not used for laminating .

Product Construction

High pressure decorative laminate (HPDL) is commonly used as the decorative surface for residential and commercial countertops and cabinets, work surfaces, laboratory surfaces, backsplashes, partitions, retail fixtures, panel applications, furniture, built-ins, signage/displays, decorative wainscoting, walls and floors.HPDL is a paper-based product created by bonding melamine-impregnated decorative papers to layers of resin-treated kraft paper under high heat and pressure. In the press, decorative papers are permanently bonded to the kraft paper to form a sheet of laminate.Laminate is made up of several components and key ingredients:

The Overlay (or Wear Layer) is made from alpha-cellulose wood fibers which primarily come from softwood trees. The lignin is removed from the fibers and they are lightly refined. The long fibers provide strength to the overlay paper. These lightweight papers are very absorbent and carry melamine resin and aluminum oxide from the impregnation process. Overlay paper is similar to the paper used in tea bags or coffee filters. In many cases, the paper machines that make filter papers also make overlay papers!

Decorative paper (solid colors and base papers used for print designs)use alpha cellulose because it does not discolor when exposed to heat and light. Fibers content includes Eucalyptus (primary), small amounts of cotton and some hardwood. The cotton fibers used are not suitable for making most types of thread. Solid color sheets contain a pacifying agent, titanium dioxide and environmentally safe pigments. Print base paper also contains TiO2 and small amounts of pigment for color control. Printed designs are usually rotogravure printed, but may also be digitally printed.

Kraft paper layers comprise soft/hard wood from FSC Controlled Wood sources and post-consumer recycled paper (similar to what is used in paper grocery bags). Kraft paper provides the strength and impact resistance to the laminate and gives it the primary performance characteristics (such as post-formability). The paper is not bleached.

Melamine resin saturates the top layer of paper for hardness and scuff resistance. Thermoset melamine resin produces a hard chemically resistant surface that is transparent and visually stable upon exposure to light. Melamine is a synthetic resin derived from the natural gas and petroleum industries. It is water white and inert to most common household chemicals.

Phenolic resin saturates the Kraft paper layers for strength and flexibility. Phenolic resin is a thermoset resin based on the chemistry developed for Bakelite over 100 years ago. It is derived from natural gas and petroleum products. The red-brown color is partially responsible for the color of the core layers in a sheet of laminate. It provides strength and impact resistance to the paper layers, as well as postforming performance to the laminate when cooked in the appropriate cycle.
