A Guide to HPL: High-pressure Laminate

Decorative surface materials have evolved in response to the ever-changing, and demanding design and construction industries. While many products have come and gone, High-Pressure Laminate, also known as HPL, has stood the test of time.

 

Originally developed and introduced in 1913 as an insulating material for electrical applications, HPL quickly gained traction as a surface solution for a wider variety of applications due to it’s durability, versatility and cost-effectiveness. Within a few years, the surface material was being used in both commercial and residential projects, for kitchen benchtops, tabletops, wall panels, furniture and more.

 

Fast forward 100 years, and HPL remains one of the most innovative and celebrated decorative surface materials on the market. The core product has remained the same, with very little need to adapt or change the composition of the product itself for it’s general use. However over the last century, the number of colours and finishes available has expanded to align with design trends.

After gaining further traction and popularity, technical advancements have been made to allow this surface to be used in unique, harsh and demanding commercial environments such as end-of-trip facilities, offices, and various applications in the healthcare industry.

 

This article explores the complexities of High-Pressure Laminate (HPL), highlighting its benefits, applications, and the reasons it excels in the competitive decorative surfaces market.

What is HPL?

High Pressure Laminate (HPL) is a versatile material widely used in construction and furniture industries due to its durability, resistance to impact, and aesthetic appeal. 

HVG Decorative Building is proud to be the exclusive distributor of Wilsonart HPL in Australia. Wilsonart is a global market leader in the manufacturing and distribution of high-pressure laminates, known for the quality and durability of their laminates, as well as the expansive range of decors and finishes on offer.

 

The production of HPL involves the following key steps:

  1. Preparation of Raw Materials: To create its durability and strength, multiple layers of paper are stacked together, then impregnated with melamine resin that provides durability and resistance to moisture and heat. Multiple layers of kraft papers create the core material, chosen for its strength and durability. Decorative Paper is the printed paper that gives the laminate its finished appearance and can be coloured and patterned. Lastly, a translucent, protective layer sits on top of the decorative paper to enhance wear and scratch resistance.
  2. Impregnation: Kraft papers are impregnated with phenolic resin, while decorative and overlay papers are impregnated with melamine resin. Both are dried in ovens once passed through their respective resin baths.
  3. Assembly of Layers: Once dried, the layers are carefully stacked in a specific order. Typically, multiple layers of kraft paper are stacked at the bottom, followed by a single layer of decorative paper, topped with an overlay paper.
  4. Pressing: The assembled layers are placed in a multi-layer press and then cured together into a single, solid sheet using high pressure typically 1,000 to 1,400 psi) and heat (around 120-150°C or 250-300°F).
  5. Cooling & Trimming: The laminate sheets are allowed to cool, to solidify resins and stabilise the laminates. The cooled sheets are then trimmed to the desired dimensions.
  6. Quality Control: The finished sheets undergo quality control checks to ensure consistency in colour, pattern, and finish. Mechanical properties like impact resistance, abrasion resistance, and chemical resistance are tested to meet industry standards.

HPL is a versatile and cost-effective material with benefits including:

  • Durability: HPL is highly resistant to scratches, impacts and abrasions.
  • Heat resistant: can withstand high temperatures without warping or melting making it suitable for benchtops and surfaces exposed to heat.
  • Aesthetic versatility: HPL is available in an extensive range of colours, textures and patterns.
  • Realistic finishes and decors: it can mimic the look and feel of natural materials such as wood, stones and metals, providing the aesthetic look of natural materials at a lower cost.
  • Stain resistance: The non-porous surface of HPL makes it resistant to stains and easy to clean.
  • Affordability and long lifespan: compared to natural materials, HPL is more affordable while still providing a similar aesthetic. It’s durability and resistance to wear translates to a longer lifespan.
  • Waterproof surface: The surface layer of HPL is impervious to water, making it an excellent choice for areas prone to moisture, such as kitchens and bathrooms.
  • Post formability: HPL can be post-formed to create curves and very tight radiuses giving a modern square edge for kitchen, bathroom and laundry benchtops and vanities.
