To UV Light UV light has two potential harmful effects on polycarbonate insulating glazing material; a yellowing of the material itself and a degradation of mechanical properties, eg. Resistance to impact. Marlon ST Longlife's surface, which has a high performance co-extruded protection system, has a high degree of resistance to the effects of natural and artificial UV light sources minimising long term yellowing and maintaining durability and toughness. UV Light Absorption Layer  Marlon st longlife has a high performance UV Absorption layer CO-extruded on the outer surface. This uv absorption layer forms a barrier to Incident UV radiation, preventing it penetrating To the body of the sheet material, so that long Term yellowing and loss of mechanical properties, Eg. Impact strength, are negligible. Marlon st longlife cuts out 98% of harmful UV Radiation, protecting those working or playing Beneath it. Loss Of Light Transmission, Increase In Yellowness Index Testing shows negligible degrading of the material's Light transmission properties or yellowing and A retention of its inherent strength and resistance To impact. This confirms marlon st longlife as a most Advanced insulating glazing material for exterior Installations with numerous advantages over Traditional glazing  materials.
All marlon st longlife sheeting has its UV Resistant surface
clearly indicated by the Removable, branded, protective film and
This should face outwards when installed. Its intrinsic impact
durability and optical clarity Combined with its valuable energy
conserving Properties make marlon st a very popular Material for
use in windows, doors, partitions And suspended ceilings.
