20/16 Polycarbonate Tubes
Our 20/16 Polycarbonate Tubes are the ultimate choice for those seeking the utmost in clarity, quality, performance, and resilience. These tubes are renowned for their impeccable optics and perfectly smooth, striation-free surfaces.
Constructed from optically clear polycarbonate, our transparent tubes find applications in a wide range of settings. Whether you’re working on stand and showcase constructions, furniture and interior design, or cutting-edge technological projects like reactors, these tubes offer the transparency and versatility you need.
While our Polycarbonate Tubes are UV stable and weather-resistant, it’s important to note that they are not intended for prolonged outdoor use, as extended exposure may lead to yellowing.
In the realm of architectural lighting, our Polycarbonate Tubes shine. With our Satin Frost Polycarbonate Tubes, you can effortlessly create stunning lighting effects. This innovative solution is particularly well-suited for lighting and architectural applications, offering white or frosted satin finishes that deliver excellent diffused light and a velvety, glare-free surface.
When it comes to shaping and modifying these tubes, the right tools are crucial. High cutting speeds and effective cooling are essential, as polycarbonate’s low heat conduction can result in overheating and localized thermal stress. Excessive friction, especially with Polycarbonate Tubes, may cause melting, leading to a sticky surface and machining difficulties. For drilling, always use a water-based cooling lubricant (e.g., an emulsion) to prevent such issues. In some cases, annealing may be necessary to eliminate internal stress.
