Good to be GREEN


PEARLY GREENTechnology: Good to be GREEN
GREEN is beneficial to living organisms.
VULCAN Polycarbonate Corrugated PEARLY GREEN ROMA sheet was developed specially for living organisms and general purposes.
PEARLY GREEN pigment reflects rather than absorbs heat producing far-red solar radiation without affecting the transmittance of the GREEN spectrum, and retains health benefiting GREEN light. This makes it easier to control the climate, particularly in the summer, and maintain optimum room temperature.*
*A large proportion of the heat increasing far-red light is reflected.
VULCAN Polycarbonate Corrugated Pearly Green sheets have a Lilac / Greenish Hue and suitable for use in archetecture. The maximum transmission of the passing light is in the green area of the visible light - exactly where the human eye is most light sensitive.
Pearly Green compared with sheets using different coating methods.
VULCAN Polycarbonate Corrugated Pearly GREEN sheet has a Lilac/Greenish Hue, and creates a significant drop in temperature (Depending on the individual application conditions, rooms are up to 15°c cooler compared to non-pigmented systems), owing to its ability to block harmful UV and IR rays. Since Pearly GREEN was specially designed for humans and living organisms, and focuses more on it's cooling abilities.

Product Strengths
Base Material
- 100% Virgin UV included raw material ensures that your sheets can withstand harmful UV rays for at least one year.
UV400 Coating
- Optical Grade SD Polyca UV400 coating as used on lenses, glasses, and sunglasses. 99.5% of harmful UV wavelengths between 290nm~400nm are blocked.
PEARLY GREEN Coating
- With particle sizes ranging from 10~60μm, PEARLY GREENis suitable for general-purpose infrared blocking applications.
Production Method
- Co-Extrusion ensures evenly spread, evenly thick base material and UV coating. (A chain is only as strong as it’s weakest link.)
High impact resistance
- 250 times the impact strength over glass and 10 times over FRP and Acrylic.
Fire Retardant
- Polycarbonate sheets produced with 100% Virgin material have a melting point of at least 190 degrees Celsius and produce only odorless smoke when burned.
Design Flexibility
- VULCAN Polycarbonate sheets can be tailored with different coatings to provide different light transmission rates and properties. Customers can choose between LiteGuide, Pearly RED, Pearly GREEN, Ti-Lite, and Valuview.
Quality Standards
VULCANPolycarbonate sheets are produced with the highest of standards available in the industry. We are the first Polycarbonate manufacture in Asia to incorporate clean rooms for all of our extrusion lines. Our latest Breyer Solid Flat sheet machine is installed in a Class 5000 clean room (the maximum number of particles per cubic foot of air of diameter greater or equal to 0.5 µm is 5000).
Machinery
We have a total of 5 co-extrusion lines, 2 for corrugated sheets and 3 for solid sheets. Our machines are imported from Toshiba-Hitachi Japan, Omipa Italy and Breyer Germany. Our co-extrusion machine uses feedblocks from the industry leading EDI (Extrusion Dies Industries) company and controlled by the also industry leading Dynisco company computers.

Raw Material
As with all of our polycarbonate products, VULCAN Pearly uses 100% Virgin Material from Mitsubishi Japan, Bayer Germany, Sabic (GE), and Optical Grade SD Polyca UV400 Coating resin from Sumitomo Dow Chemicals Japan to protect itself from harmful UV rays.
VULCAN Polycarbonate Sheets are produced using advanced Co-Extrusion process to ensure an evenly UV coated surface. We use feedblocks from EDI (Extrusion Dies Inc.) and the extrusion process is controlled from Dynisco systems.
Feedblocks: EDI (Extrusion Dies Industries) to ensure even material flow.
Co-extrusion process is fully computer controlled by Dynisco systems.
Impurity leads to less quality, which is why VULCAN Polycarbonate sheets are produced in clean rooms; the cleaner the environment, the cleaner the sheets, and hence a longer lifespan.
Class 5000 Clean Rooms
VULCAN Pearly Series can be made into the following Profiles:

Optional Plus+ surface treatment provides added light softening properties. (MOQ required)
