Polycarbonate Tube Polycarbonate Tube Polycarbonate Tube
18/14 Polycarbonate Tubes
Our 18/14 Polycarbonate Tubes are the epitome of quality, performance, and clarity in extruded tube technology. They boast impeccable optical properties and a seamlessly smooth, striation-free surface.
These optically pure Polycarbonate Tubes find their applications in a wide range of industries, from stand and exhibition construction to interior design and technical applications like reactors.
While our Polycarbonate Tubes offer reasonable UV stability and weather resistance, it’s important to note that they are not intended for prolonged outdoor use, as extended exposure may lead to yellowing.
Architectural lighting enthusiasts will find these Polycarbonate Tubes perfect for crafting high-quality, design-oriented lighting solutions. Our Satin Frost Polycarbonate Tubes, in particular, are a groundbreaking choice for lighting and architectural applications. The white or frosted satin finish delivers excellent diffused lighting, ensuring a velvety, glare-free experience.
For those who need to customize their Polycarbonate Tubes, they can be cut, sanded, and drilled with the right tools. However, it’s crucial to maintain high cutting speeds and effective cooling, as Polycarbonate’s low heat conductivity can result in overheating and localized thermal stress. Excessive friction, especially during machining, can cause melting and create a tacky surface, so always use water-based cooling lubricants, such as emulsions. In some cases, annealing may be required to eliminate internal stress.
