12/9 Polycarbonate Tube
Our 12/9 Polycarbonate Tubes are the ultimate choice for those seeking top-notch quality, outstanding performance, and long-lasting durability. These tubes are renowned for their exceptional clarity, making them the premium choice in the extruded tube market. The flawless optics and striation-free surface of our Polycarbonate Tubes ensure a perfectly smooth appearance.
Designed to be optically pure, our transparent Polycarbonate Tubes find applications in a variety of industries, including stand and exhibition construction, furniture and interior design, as well as technical uses like reactors.
While our Polycarbonate Tubes offer reasonable UV stability and weather resistance, they are not intended for extended outdoor use, as prolonged exposure may cause yellowing.
For creative, design-oriented applications in architectural lighting, our Polycarbonate Tubes are a game-changer. Our Satin Frost Polycarbonate Tubes, in particular, open up exciting possibilities for lighting and architectural projects. The white or frosted satin surfaces deliver excellent diffused lighting, creating a soft, non-glare illumination.
Working with Polycarbonate Tubes requires the right tools and techniques. High cutting speeds and effective cooling are essential due to their low heat conduction, which can lead to overheating and localized thermal stress if not managed properly. Excessive friction, especially when machining Polycarbonate Tubes, can result in melting, leading to a sticky surface and machining difficulties. When drilling, always use a water-based cooling lubricant, such as an emulsion, to prevent such issues. Annealing may also be necessary to eliminate internal stress in the material.
