In the clinical diagnosis and treatment of orthopedics and plastic surgery, high-quality external fixation serves as a critical foundation for ensuring stability at the injury site and facilitating smooth recovery. Traditional plaster casts, however, suffer from several drawbacks—being bulky and uncomfortable, requiring cumbersome application, and losing effectiveness upon contact with water—which not only increase the workload of clinicians but also compromise patients’ daily rehabilitation experience.

Nanjing Shuangwei Designed to meet clinical needs Fiberglass Casting Tape. It employs a glass-fiber‑woven substrate combined with a moisture‑curing polyurethane formulation, offering the dual benefits of high‑strength support, lightweight wearability, and ease of use, thereby providing a mature solution for limb immobilization across multiple scenarios. 

I. Product Core Overview

Shuangwei Fiberglass Casting Tape made from a glass-fiber‑woven base fabric impregnated with moisture‑curing polyurethane, this 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. 

II. 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.

Note: This product does not come into direct contact with the human body.

III. Standardized Operational Guidelines for Smoother Clinical Application

▶ How to Apply a Bandage Splint (Splint-Type)

Selection: Select the appropriate size of polymer cast based on the anatomical location (F3/F4 is recommended for the upper extremity, and F5/F6 for the lower extremity).

Preparation: Remove the bandage while wearing latex or PE gloves, and lay it flat, folding it into 4–7 layers according to the length of the immobilized area to form a bandage support (4–5 layers for the upper limb, 6–7 layers for the lower limb), then trim both ends evenly.

Bandaging: Place the bandage pad over the injured area and secure it with a standard medical gauze bandage.

Accelerated curing: To accelerate the curing process, after bandaging is complete, lightly mist the surface of the bandage with a small amount of clean water.

Shaping: The dressing is meticulously contoured to match the morphology of the affected limb, and the bandage layers are repeatedly smoothed to enhance interlayer adhesion, thereby improving fixation strength and surface smoothness. 

▶ Bandage-wrapping technique

Preparation: Select the appropriate product size based on the patient’s fixation site, and wear latex gloves prior to application. Line the fixation area with a tubular bandage liner, and if necessary, add an additional cotton roll.

Submersion: Immerse the self‑adhesive bandage in room‑temperature water for 3–4 seconds, then squeeze it 2–3 times. If used without soaking, the curing time will extend to 4–6 minutes (the higher the water and ambient temperatures, the faster the curing process).

Entanglement: Wrap in a spiral fashion with moderate pressure, overlapping the bandage by 1/2 to 1/3 of its width, and ensure an appropriate level of tension (too loose will reduce interlayer adhesion, while too tight will increase the load on the affected area).

Styling: Wrap 5–6 layers around the support areas, and 3–4 layers on non-support areas; after wrapping, gently smooth the surface to ensure evenness, then allow it to cure and set naturally.

▶ Demolition Precautions

When window opening or removal of fixed components is required, it is recommended to use an electric drywall saw. The blade of the electric drywall saw is sharp and may become hot during operation; take care to avoid cuts or burns to the skin. Users are advised to read the product manual carefully and follow proper operating procedures. 

IV. Comprehensive Specification Coverage, Adaptable to Multiple Body Areas

The product line offers a full range of F2–F6 specifications, covering all immobilization needs from children’s wrists to adults’ lower limbs. It is uniformly packaged in cartons of 50 rolls, making it suitable for stocking and use across various settings, including outpatient clinics, hospital wards, and emergency departments.

This polymer-based immobilization bandage delivers an efficient user experience, reliable stabilization, and exceptional comfort, providing high‑quality external fixation support across multiple specialties, including orthopedics and plastic surgery, and working hand in hand with healthcare professionals to enhance patients’rehabilitation outcomes.
