Durability
As the name implies, Marlon ST Longlife has impressive durability
characteristics with a high degree of resistance to the harmful
effects of extended usage under natural sunlight or artificial UV
light conditions.

Resistance
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.
