Material comparison

Polycarbonate vs Acrylic: Toughness vs Optical Clarity

Acrylic can win on scratch resistance and optics. Polycarbonate wins on impact when the lens must survive handling or assembly.

Material comparison

Optics first, then ask about impact

Both can be molded clear. The service environment breaks the tie.

Display covers that never see impact may favor acrylic for scratch and clarity.

Handheld devices and industrial windows usually need polycarbonate impact reserve.

Resin choice

Typical versus Typical at a glance

Use this routing before you lock the BOM. NetProto molds both once the resin is specified on the quote.

Typical polycarbonate

  • High impact for lenses and machine guards
  • UV stabilized grades for outdoor exposure
  • Higher material cost than PMMA

Typical acrylic (PMMA)

  • Excellent light transmission and surface hardness
  • More brittle under impact or snap loads
  • Lower cost for static display windows

Common questions

Can either be molded in color?

Yes. Tinted PC and PMMA are common. Match the colorant system to the optical grade.
