PMMA Tube
PMMA tube (acrylic tube) — clear, lightweight and impact-resistant. UV-stabilized options, custom lengths and machined ends. Datasheet & compatibility info available.
Description
PMMA tube, commonly called acrylic tube or organic tube, is a clear thermoplastic tube prized for high optical clarity and light weight. It is widely used for sight glass tubes, machine guards, lab equipment and decorative applications. We offer UV-stabilized grades, custom lengths, and CNC-machined end treatments for easy installation.
Quick highlights
- Material: PMMA (Acrylic) — clear, high optical clarity.
- Typical temperature: –20℃/+100℃
- Impact & scratch: Better toughness than glass for impact; scratch resistance less than glass — protective coatings available.
- Options: UV-stabilized, anti-static, flame-retardant variants; custom drilling and end machining.
- Applications: sight tubes, protective guards, lab tubes, and lighting diffusers.
Typical specifications
PMMA vs PC vs Glass — short guide
PMMA provides excellent optical clarity and is lightweight. However, polycarbonate (PC) offers superior impact resistance while borosilicate glass gives the best chemical and high-temperature performance. Therefore, choose PMMA when optical clarity and cost are priorities; choose PC for impact-prone locations; choose glass for high temperature or aggressive chemicals.
Features & benefits
- Superior clarity: Near-glass transparency for accurate visual inspection.
- Lightweight & easy to machine: Easier handling and lower shipping costs.
- Customisable: Drilled holes, countersinks, machined seats, and bonded assemblies per drawing.
- Cost-effective: Competitive price for non-extreme temperature/pressure applications.
Applications
Sight tubes, gauge covers, protective guards, instrument housings, decorative lighting tubes, and low/medium temperature process lines.

FAQ
- 1. Is PMMA safe for outdoor use?
- Standard PMMA can yellow under prolonged UV exposure. Use UV-stabilized grade for outdoor installations
- 2. Can PMMA be used for pressure sight tubes?
- PMMA is suitable for low/medium pressure. For higher pressure, choose thicker walls and proper end fittings or consider PC/borosilicate glass. See datasheet for guidance.
- 3. How should I clean PMMA?
- Use mild soap and water; avoid solvents such as acetone or MEK, which can craze the surface. Refer to the compatibility PDF.
