Raw Material
Makrolon® Polycarbonate resin produced by Bayer AG.
Applications
Roof glazing, canopies and interior decoration for industrial, civil &
public buildings (eg. railway and metro station roofing).
Stadiums, gymnasium, clubs and recreations centers (eg roofing for sunroom, swimming pool and conservatory).
Commercial greenhouses, & aquafarm canopies.
Light box, sign, POP advertisement boards.
New Coextrusion Technology
Based on the new technology developed by bayer, the distributions of the
UV-layer thickness is homogenous and compatible bound as an intergral part
of the PC panel. Coextruded sunlight PC panel provides advantageous
weathering protection over coated panels as offered by some companies.
Melt Distribution Technolgy
Specially designed melt pump &
adapter are core of the coextrusion system to ensure high quality
products.
Fully Automatic Remote Control
Technology
The production line is fully automatic (Computer Aided Manufacturing) with
precise control of processing parameters such as feeding speed,
temperatures, pressures, output rate etc.. Various instruments are used
for process and quality control. This line can remote-controlled via
computer network and represent one of the most advanced co-extrusion
machinery in the plastic industry.

PC panel can maintained excellent properties in a wide temperatures range -40°C to 120°C. Its brittleness temperature is -110°C and its soften temperature is 150°C.
Flame Resistance
During burning, PC panel will neither generate toxic gas such as cyanide,
acrylaidehyde, sulphur dioxide and so on, nor corrosive substances.
Easy Installation
PC panel can be successfully bent along the channel direction in normal
atmospheric temperature. The minium radius of the curvature of the twin
wall PC panel is 175 times of its thickness.
