LiteGuide GRECA Series

LiteGuide GRECA Series

LiteGuide – Softens and disperses light evenly, which suits plants and flowers, which burns when encountering direct sunlight and is best avoided.

Also suitable for Signs and Billboards, which provides good aesthetics.

VULCAN GRECA (76/18) Polycarbonate sheet has the widest span, at 1170mm with 16 corrugations, of all VUCAN corrugated profiles.

GRECA profile is most often used in the Americas.

LiteGuide Series

VULCAN LiteGuide filters incoming sunlight and interior lighting into soft and dispersed light, which eliminates burn on plants, vegetation, animals and human beings. The light softening properties comes from VULCAN's proprietary LiteGuide resin added to the Covestro base, and with the help of Clariant CESA Light UV and Light Stabilizers co-extruded on the surface, maximizes the lifespan of your VULCAN LiteGuide polycarbonate sheet.
 

Product Strengths

Base Material 
VULCAN polycarbonate sheets use only 100% Virgin Covestro UV stabilizer included master-batch.

LiteGuide Material 
Designed to break up and distribute light evenly, LiteGuide will reduce hot spots and diffuse light.

LiteGuide Technology 
LiteGuide softens and disperses light evenly, which suits plants and flowers, which burns when encountering direct sunlight and is best avoided. LiteGuide sheets are also suitable for Signs and Billboards, which provides good aesthetics.

LiteGuide Transmission Rate
Excellent Light transmission - 88% VIS transmission rate with complete light dispersion.

High Impact Resistance
250 times the impact strength over glass and 10 times over FRP and Acrylic.

Base Material
VULCAN polycarbonate sheets use only 100% Virgin Covestro UV stabilizer included master-batch.

UV Resistant Coating
Co-extruded with the Base Material, the Clariant CESA Light UV and Light Stabilizers blocks harmful UV rays from 280~400nm. With co-extruded UV protection, VULCAN Polycarbonate sheets last 10 years or more.

Clean Room Manufacturing
VULCAN Sheets are produced in Class 5000 clean rooms to ensure an impeccable quality.

Production Method
Co-Extrusion ensures evenly spread, evenly thick base material and UV coating.
