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.

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.
