UV Resistant Polycarbonate

Description

VULCAN Solid FLAT UV Resistant Polycarbonate sheet

Solarshield SOLID Flat sheets are made from UV resistant polycarbonate material plus IR (Infrared) blocking additives.

Even with Solarshield additives, this UV resistant polycarbonate Solid FLAT sheet keeps visible light transmission rates identical to clear glass, and is also capable of reflecting infrared-induced heat by 99% and reducing temperatures to the max. 15 °C / 59 °F.

With time, growing knowledge, improvements in manufacturing, and the constant development of proprietary additives, we have come to understand the advantages of using polycarbonate in place of traditional glazing material.

Polycarbonate sheets are 250 times over glass, 10 times over FRP and Acrylic sheets in impact strength, in addition, its lightweight, ease of installation, fireproof and weathering-resistant properties make them the perfect choice for civil construction and safety glazing.

For example, sheets 6mm and above are capable of stopping low-powered rounds, and are often laminated to create bulletproof glass to stop higher-powered rounds or complex security threats; PC sheets can also be thermoformed into riot shields for law enforcement, and polycarbonate domes for skylights.

PRODUCT OVERVIEW

Solarshield – Transparent IR Protection

VULCAN Solarshield comes in two colors, Greenish and Blue, and is an inorganic, nano-structured, IR-protection based pigment designed as a solar heat protection application.

Solarshield attenuates longer wavelength heat-producing infrared radiation very effectively through reflection, but at the same time, retains high clarity, virtually unnoticeable compared to standard VULCAN Valuview Clear sheets.

When co-Extruded with UV and light stabilizers hence becoming a weathering, UV resistant polycarbonate sheet, there is no risk of IR-protection loss, nor does it change color over time.

One of the biggest advantages of Solarshield polycarbonate solid flat sheets when compared to other plastic glazing material with heat reduction properties is that Solarshield blocks and reflects IR, not absorb.

This means that, while older technology such as TiO2 coated sheets absorbs solar radiation and increases the temperature of the whole material, Solarshield sheets remains at a cool and steady temperature.

For high coefficient of thermal expansion rates on materials such as plastics, this provides a huge advantage as less thermal expansion and contraction translates to longer lifespan of the material, which is why we provide a limited 15-year warranty VULCAN Solarshield Solid Flat sheets.

Product Strengths

Solarshield Material

Solarshield is an IR-reflection additive that is designed to work with polycarbonate sheets as a solar heat protection application that attenuates longer wavelength heat-producing infrared radiation very effectively through reflection. Reflected IR means that surface temperatures of the PC sheets remains low, which prolongs the lifespan of the sheet. VULCAN Solarshield comes with a 15-year limited warranty*.

Solarshield Technology

Solarshield is an inorganic, nano-structured pigment clear transparent in polycarbonate. Being weathering stable means no loss of IR-protection during weathering.

Excellent Heat Reflective Properties

Excellent Heat Reflection – Controlled NIR (780~2500nm) – Capable of reducing temperatures up to 10°c* in a ventilated environment.

Light Transmission Rate

Excellent Light transmission – Controlled VIS (380~780nm) – 40% light transmission rate.

High Impact Resistance

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

Base Material

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

Total UV Protection

Co-extruded with the Base Material, Avient CESA Light UV and Stabilizers blocks harmful UV rays from 280~400nm. With CESA Light coating, VULCAN UV resistant Polycarbonate sheets are able to last 15 years or more.

Clean Room Manufacturing

VULCAN UV resistant polycarbonate sheets are produced in ISO Class 7 (FED STD 209E equivalent Class 10,000) clean rooms to ensure impeccable quality.

Production Method

Co-Extrusion ensures evenly spread, evenly thick base material and UV coating.
*Certain conditions may apply.

Properties

Solarshield is an Infrared (IR) reflective material that has an effect similar to low emissivity (Low-E) glass, but at a fraction of the cost. Solarshield effectively reflects IR but still retains a very high light transmission rate.

Places to Use

Suitable for areas which require all-day visibility, but still effectively block heat during a bright sunny day.
