What Is Fiberglass Casting Tape?
Fiberglass Casting Tape is pre-impregnated with water-activated polyurethane resin, designed to cure quickly into a hard, strong, lightweight cast for multiple applications.

How does fiberglass casting tape work?
Preparation
Select the appropriate product size according to the patient’s immobilization site and wear latex gloves before operation. Apply tubular stockinette over the area to be immobilized; a cotton roll may be over‑wrapped if necessary.
Water Activation
Immerse the sealed tape in room‑temperature water for 3‑4 seconds, then squeeze it 2‑3 times. If applied without water immersion, curing time will extend to 4‑6 minutes. Higher water and ambient temperatures accelerate the curing speed.
Wrapping
Wrap with moderate tension in a spiral pattern, overlapping each layer by 1/2‑1/3 of the tape width. Maintain proper tightness: excessive looseness reduces inter‑layer adhesion, while over‑tight wrapping increases burden on the injured site.
Molding
Apply 5‑6 layers for weight‑bearing support areas and 3‑4 layers for non‑support areas. After wrapping, gently smooth the surface and allow it to cure and set naturally.

How to Choose High-Quality Fiberglass Casting Tape

Not all fiberglass casting tape products meet the same safety and performance standards, so you should prioritize certified products from reputable suppliers. Shuangwei Fiberglass Casting Tape is a high‑performance external fixation consumable. The product features a tubular backing design that ensures smooth handling and easy shaping; once cured, it exhibits high strength and a flat, well‑formed profile. It is widely applicable in orthopedic fixation, plastic surgery, limb correction, and skeletal support and protection, with a full range of specifications to meet the fixation needs of all body regions.

Six Core Advantages That Directly Address Key Clinical Needs

1. Excellent forming performance

The base material exhibits excellent flexibility, allowing it to conform and mold easily even in complex areas such as limb bends and joints. The resulting shape is smooth and closely adheres to the surface, meeting the fixation requirements of various limb morphologies.

2. Smooth surface after curing

High-quality fiberglass substrate combined with a special formulation ensures a smooth, more conforming bandage texture during application; after curing, the surface is smooth and even, resulting in a neater, more uniform appearance.

3. Easy to operate, with controllable curing

It employs a water‑activated resin formulation, offering a simple, easy‑to‑learn application process with controllable curing time. After immersion in water, the bandage does not stick to the gloves, and the fabric roll maintains an optimal tension. Initial curing occurs within 5–8 minutes after wrapping, and full load‑bearing capacity is achieved after 30 minutes, allowing healthcare professionals to manage their workflow efficiently and minimize patient discomfort during waiting periods.

4. Lightweight and breathable, waterproof and abrasion-resistant

The product weighs only one-fifth of a conventional plaster cast, significantly reducing the burden on the wearer. Its knitted base material offers excellent breathability, minimizing skin irritation and unpleasant odors even with prolonged immobilization. Once cured, it achieves a strength up to 20 times that of standard plaster, providing stable and reliable support. Additionally, it boasts water‑resistant properties that withstand moisture and humidity, allowing patients to bathe normally during immobilization and making daily activities more convenient.

5. Economical and practical, with reduced consumable usage

The amount and number of layers of bandage required to achieve equivalent immobilization are significantly lower than those needed for conventional plaster casts. Immobilizing the upper limb requires only 5 layers, while the lower limb requires just 6, effectively reducing material costs per application.

6. Gentle and low-irritation, safe to use

The product is non-toxic, non-irritating, has a mild fragrance, exhibits excellent skin compatibility, and is suitable for most skin types.
