Resopal® Collection Stones and Materials

Decorative high-pressure laminate (HPL) sheets in accordance with EN 438 and ISO 4586, with a stone effect finish.

The sheets consist of layers of cellulose fibrous material (normally paper) impregnated with thermosetting resins and bonded together in a high-pressure process. The process, defined as a simultaneous application of heat (≥120°C) and high specific pressure (≥5 Mpa), provides flowing and subsequent curing of the thermosetting resins to obtain a homogenous non-porous material (≥1.4 g/cm³) with the required surface finish.

The formaldehyde emission level is far below the limit for wood-based materials. Due to their very low permeability RESOPAL®-HPL sheets bonded to wood-based substrates act as a barrier against possible formaldehyde emissions coming from the substrates.

There is no migration affecting foodstuffs and, consequently, the laminates are approved for contact with foodstuffs.

The non-porous surface and edges are easy to disinfect with hot water, steam and all types of disinfectants used in hospitals and other commercial facilities.

The decorative surfaces are resistant to common household solvents and chemicals. They do not suffer from corrosion and oxidation, and they do not need any further surface protection (lacquers or paints).

Laminates are difficult to ignite and have properties that retard spread of flame, thus prolonging evacuation time. Due to incomplete burning, as with many organic materials, hazardous substances are to be found in the smoke. However, HPL is capable of meeting the best performance for organic surfacing materials specified in the French standard NFF 16101 (at least class F2 for smoke density and toxicity). HPL is not classified as a hazardous substance.

Technical characteristics:

• Calorific value: 18–20 MJ/kg.
• Heavy metals: Does not contain toxic compounds of antimony, or heavy metals barium, cadmium, chromium III, chromium VI, lead, mercury and selenium.
• Material incompatibility: Strong acids or alkaline solutions will stain the surface.
• Ignition temperature: 400°C (approximately).
• Electrostatic behaviour: Surface resistivity is between 10^9–10^12 ohms and a chargeability of V <2 kV according to CEI IEC 61340-4-1 (HPL is an antistatic material).
• Does not contain Pentachlorophenol (PCP).
