SABIC Innovative Plastics 5
• Lightweight – an outstanding balance of low
weight and high stiffness enables lightweight
structures with greater spans to be designed and
easily installed
• Ease of installation – it can be easily cut on site
using conventional tools and can be cold-formed
into tight radii without pre-forming. Material
wastage is minimal as the sheet will not crack or
split when cut, sawed or drilled
• Excellent energy efficiency – the multiwall
construction traps air between the layers,
which ensures outstanding thermal insulation
performance
• Low flammability – the high performance Lexan
multiwall sheets in this brochure are characterized
by both exceptionally good flame resistance,
according to Underwriters’ Laboratories (UL 94),
and excellent heat stability
• UV resistance – the proprietary surface treatment
provides almost total resistance to degradation
from UV radiation in sunlight, thereby helping to
maintain long-term high light transmission
• Comprehensive warranty – most of the Lexan
Thermoclear products carry a minimum 10-
year limited written warranty against excessive
yellowing, loss of light transmission and loss of
strength due to weathering
• Broad portfolio – a range of structures, coatings,
colors, dimensions and gauges enables glazing
performance to be tailored to help meet specific
performance criteria
• Environmental standards – in many cases these
high performance polycarbonate sheet products
may be recycled
Manufactured at six sites worldwide, Lexan
Thermoclear sheet is helping customers around
the world to develop imaginative glazing with
the right balance of thermal insulation and light
transmission. Customers can choose between two-,
three-, five- and six-wall constructions, in a variety
of thicknesses and sizes, to suit a broad range of
design requirements. In applications where superior
stiffness is required, SABIC Innovative Plastics offers
X-structures.
