Fiberglass casting tape, also called fiberglass cast tape or orthopedic cast tape, is a lightweight, durable, and water-resistant material used to create a modern fiberglass cast. It's the modern alternative to traditional plaster casts, offering superior strength while being significantly lighter and more breathable.
Key Benefits
Lightweight & Strong – Up to 4x lighter than plaster while maintaining excellent rigidity.
Water-Resistant – Can get wet briefly without compromising cast integrity (with proper padding and cast care).
Fast Setting – Sets in 3–5 minutes and fully cures in approximately 20 minutes.
Breathable – Open weave design allows air circulation for patient comfort.
Radiolucent – Allows clear X-ray imaging without cast removal.
Available in Multiple Colors – Patient choice improves compliance, especially with children.
