Explore the Technical Facts Behind Our High-Pressure Laminate Sheets.

Properties:

Resistant to Weathering as per EN ISO 438-2 and EN ISO 4892-2
Having light fastness as per EN ISO 4892-3
Mechanically Sturdy Having high Flexural Tensile Strength as per EN ISO 178
High Screw holding strength
Longest Formaldehyde Emission as per EN 717-i Suitable for all exterior application Available in wide range of attractive colors and textures, provide healthy atmosphere as it does not support micro organic Growth.
Leminex Exterior Cladding panels can be exposed to combined action to sunlight and atmospheric such as rain and wind deposits.
Exhaust Fumes and acid rain can have mild effect on surface.not affected by thermal shocks and maintains its physical & mechanical properties.
Extreme Climate Change Such As from -10°C. to +60°C. or from a dry climate to 90% relative humidity do not affect the appearance of the properties of the panel.

Technical Area
