Principles and Product Features of Low-Temperature Thermoplastic Sheets

Low-temperature thermoplastic sheets are a type of specially synthesized polymer material primarily used for orthopedic external fixation, orthotics, and the fabrication of braces. The following outlines the principles and product features of these sheets.

Principles of Low-Temperature Thermoplastic Sheets

Low-temperature thermoplastic sheets are a novel medical material created through specialized physical and chemical processing of synthetic polymers. Key characteristics include radiolucency (they do not absorb X-rays) and the ability to be reheated and remolded—either entirely or locally—if the initial molding is unsatisfactory. They are easy to handle and convenient for fixation, making them the ideal external fixation material for radiotherapy positioning.

Product Features

A: High Moldability: They soften completely when placed in hot water at approximately 70°C and can be stretched and molded as desired; the process is simple and quick.

B: Memory Function: If the molding is unsatisfactory, the material can be returned to 70°C hot water to soften again; it reverts to its original size and shape, allowing for remolding and repeated use.

C: Good Breathability and Water Resistance: The sheets feature a perforated mesh design that promotes skin ventilation, heat dissipation, and perspiration, helping to prevent skin redness, swelling, or itching. Additionally, patients can bathe while wearing the device, which improves their quality of life.

D: Lightweight, Thin, and Strong: With a thickness of 3–7 mm, these sheets weigh only one-sixth as much as plaster casts. They possess high toughness, are resistant to breakage or snapping, and offer safe, reliable performance without causing allergic skin reactions.

E: Adhesive Capability: During the molding process, surfaces or cut edges can be bonded together easily, simplifying and speeding up the procedure for medical professionals.

F: Excellent X-ray Transparency: Patients can undergo fluoroscopy or X-ray imaging while wearing the device; it does not interfere with or degrade the quality of the imaging results.

G: Easy Fixation and Removal: They can be secured using hook-and-loop straps, making the device convenient to wear while maintaining breathability. H: Convenient wound access: The product offers flexible application, allowing for customized openings based on the patient's condition, which facilitates subsequent dressing changes and monitoring of wound healing.
