What is a PMMA tube？

As a professional PMMA tube manufacturer in China, we produce various sizes and types of PMMA tubes. So, what exactly is PMMA tube?

PMMA tube, commonly known as plexiglass tube or acrylic tube, is chemically named polymethyl methacrylate (PMMA). Today, we'll mainly discuss colored PMMA tubes and large-diameter PMMA tubes.

Colored PMMA Tubes – Beyond Decoration

When a project requires color, JE doesn't use surface spraying or coating processes. Instead, we incorporate high-performance masterbatch into the raw materials before extrusion molding. The color permeates the PMMA tube wall, meaning there will be no peeling, scratching, or fading, and the appearance remains uniform even after cutting, drilling, or polishing.

We can produce a wide variety of products: from translucent pastel colors that diffuse soft light, to dark opaque colors that block 100% of visible light, to fluorescent colors for safety markings, and even metallic tubes for designer furniture or retail displays. Each color has its unique functional advantages. For example, white, semi-transparent PMMA tubing serves as a highly efficient light diffuser—after installing LED strips inside, the tubing emits light uniformly along its entire length. We have supplied this type of PMMA tubing for numerous architectural lighting projects. Black, opaque PMMA tubing, on the other hand, completely absorbs stray light, making it ideal for sensor housings or darkroom equipment. For chemical plants, we produce color-coded tubing (red for fire extinguishing fluids, blue for water, and yellow for fuels) so operators can quickly identify pipelines without opening the system.

Another popular product in our catalog is amber or UV-blocking PMMA tubing. By adding specific organic dyes, we create tubing that absorbs UV and blue light up to 450 nanometers while remaining visually transparent. This protects photosensitive drug liquids or photoinitiated adhesives from damage during processing. I have worked with several medical device manufacturers who now specify this PMMA tubing for their drug delivery systems because it extends product shelf life without the need for expensive, opaque metal tubing.

Large-Diameter, Thick-Walled PMMA Tubes – Structurally Transparent

Many people consider PMMA tubing to be small, insignificant components. In our extrusion plant, we routinely produce PMMA tubing with outer diameters up to 300 mm and wall thicknesses up to 10 mm. The performance of these large-diameter tubes is nearly comparable to that of transparent structural beams. Their flexural modulus (approximately 3300 MPa) and tensile strength (70 MPa) allow them to withstand moderate loads without metal reinforcement. For example, thick-walled PMMA tubing can be used as pillars for museum display cases, protective sleeves for industrial robot arms, or reaction columns in pilot-scale chemical reactors.

The advantages compared to glass are obvious – large glass tubes of the same diameter would be extremely heavy and dangerous to handle. Compared to polycarbonate, the advantages lie in transparency and surface hardness. Polycarbonate is easily scratched and yellows outdoors, while our PMMA tubing retains its shine and transparency for years. We have also developed an annealing process for thick-walled tubes that eliminates internal stress and reduces the risk of solvent cracking. As a research and development engineer, I always remind customers that the processing of large PMMA tubes must be done with extra care (coolant is essential to prevent heat buildup), but once installed, it offers a unique combination of transparency and strength.
