LiteGuide TRIMDEK Series
LiteGuide TRIMDEK Series
LiteGuide – Though belongs to the clear polycarbonate sheet category, has additives that softens and disperses light evenly, while still retaining a very high visible light transmission rate.

Best suited for greenhouse applications and commercial skylights, as we know humans and other living organisms would all like to avoid sunburn. Also suitable for Signs and Billboards.

VULCAN TRIMDEK (190/27) polycarbonate sheet

VULCAN TRIMDEK polycarbonate sheet matches closely to the TRIMDEK metal roofing profile used in Taiwan and most Asian countries.

The four 131mm valleys in between crests each have three additional low profile corrugations specially designed for better drainage.

The tall and angular crest corrugations combined with additional shorter crests at the valleys creates a very industrialized look, making TRIMDEK corrugated profile a very popular choice when building factories or warehouse facilities.

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 MaterialVULCAN polycarbonate sheets use only 100% Virgin Covestro UV stabilizer included master-batch.

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

LiteGuide TechnologyLiteGuide 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 RateExcellent Light transmission - 88% VIS transmission rate with complete light dispersion.

High Impact Resistance250 times the impact strength over glass and 10 times over FRP and Acrylic.

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

UV Resistant CoatingCo-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 ManufacturingVULCAN Sheets are produced in ISO Class 7 (FED STD 209E equivalent Class 10,000) clean rooms to ensure impeccable quality.

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