What is an Acrylic Tube? Definition, Properties, and Applications

Definición en una frase

An acrylic tube is a hollow cylindrical product made from polymethyl methacrylate (PMMA), valued for its exceptional optical clarity, weather resistance, and versatility across industries.

Explicación detallada

Acrylic tubes, also known as plexiglass tubes, are transparent thermoplastic cylinders manufactured primarily from PMMA. This material is renowned for its high light transmittance (up to 92%), excellent UV resistance, and moderate mechanical strength. Acrylic tubes are available in a wide range of diameters, wall thicknesses, and lengths, and can be produced via two main processes: extrusion (for cost-effective, uniform tubes) and casting (for superior optical quality and large diameters). After forming, tubes are often annealed to relieve internal stresses, then cut, polished, or even colored/textured to meet specific requirements.

Acrylic tubes are lightweight, easy to machine, and bond well with adhesives and solvents. Their clarity and weatherability make them a preferred alternative to glass in many applications, while their moderate impact resistance can be enhanced through material modification. Service temperatures typically range up to 80–100°C, and the tubes are available in clear or colored variants.
