RP cast acrylic aquarium panels are the clear structural walls behind home aquariums, restaurant tanks, shopping-mall exhibits, and themed attractions. Cell-cast PMMA gives far higher clarity, polishability, and long-term water performance than extruded acrylic or glass — which is why every premium public aquarium is built on cast acrylic.

Why cast acrylic for aquariums

  • Huge panels, one piece. Cell-cast panels can be produced tens of millimeters thick and several meters wide — no unsightly joints across the main viewing window.
  • Optical clarity. ~92 % light transmission with a glass-like refractive index; edges can be flame-polished to invisibility.
  • Half the weight of glass. A 50 mm acrylic window weighs about the same as 12 mm glass — far cheaper to support and ship.
  • Bondable. Panels can be edge-bonded into cylinders, boxes, and curved walls; the bond line is engineered to match the parent material.
  • Safe by failure mode. Acrylic yields and cracks slowly instead of shattering into sharp shards like glass.

How we quote an aquarium panel

Send us (1) tank dimensions and water depth, (2) whether the panel is flat, curved, or a tunnel, (3) thickness from your engineer or our recommendation, (4) edge finish and mounting detail. We will size the acrylic against hydrostatic pressure, confirm shipping format, and quote panel + fabrication together.

Share your tank sketch or drawing — we will return a thickness recommendation and CIF quote in 1–2 working days.
