What are the advantages of polymer plywood over traditional gypsum, and what is its market prospect?
1. Polymer splint has high hardness and light weight: the polymer bandage hardness after curing is 20 times that of traditional gypsum, which ensures the reliable and firm fixation of polymer splint. Less fixing materials and light weight, equivalent to 1/5 of gypsum weight and 1/3 of gypsum thickness, can reduce the load of affected parts, reduce the load of functional exercise after fixation, promote blood circulation and promote healing. The plaster splint was made by the doctor before operation. Because gypsum is still brittle after solidification, it will fracture when the load is too large, which will lead to the displacement of the fracture after repair. Polymer splint effectively reduces the possibility of re-injury of the affected part under the action of external force, thus effectively ensuring fixation.

2. Good air permeability of polymer splint: The base fabric woven by polymer bandage with special raw materials and advanced technology has excellent flexibility and air permeability, and the polymer splint made of it is beneficial to the air permeability of skin.

3. The curing speed of polymer splint is fast: the curing process of polymer splint is fast. Curing begins at 10 minute after unpacking, completely cures in 20 minutes, and can be loaded in 30 minutes. It takes about 24 hours for the plaster bandage to completely harden and bear the load.

4. Polymer splint has excellent X-ray linearity: Polymer splint has excellent radiation permeability and clear X-ray effect, which is helpful for doctors to know the healing of the affected limb at any time during the treatment. However, the permeability of gypsum is poor, and sometimes the healing situation can only be clearly understood after the fixation is removed. So as to avoid that gypsum sometime passes through aft being removed.

X-ray examination found that it did not meet the healing standard and needed to be bandaged again.

5. The invention is easy to operate, soft and good in plasticity: easy to operate. Take it out and soak it in water for 5- 10 second, then wrap it with elastic bandage or ordinary gauze bandage.

6. Polymer splint is comfortable and safe: polymer bandage adopts high-quality polyurethane adhesive (imported polyurethane composite, with appropriate viscosity and exothermic temperature during curing and small shrinkage after curing), and polymer splint is light and comfortable.

7. Polymer splints have a wide range of applications: external fixation in orthopedics, orthopedic appliances in plastic surgery, auxiliary devices for artificial limbs, and auxiliary tools. Local protective support such as burns department.

Polymer splint is a derivative product of polymer bandage. Its main structure is an inner polymer bandage layer, which is composed of polyurethane glue and glass fiber. We usually see colorful bandages and splints for fractures in Korean dramas, as well as the interfaces of high-voltage lines, including sewage pipes wrapped in American dramas and even motorcycles.

Polymer plywood is much more expensive than traditional gypsum, but because of its excellent quality, it has been widely used in many countries, and medical and civil industries have become mainstream products. 10-50 dollars is still acceptable.

3M is recommended for import. Their polyurethane glue is very good and its high quality is guaranteed.

Domestic products can be made in Chen Xi, the largest processing factory in China, just as the iphone is made by Foxconn, with high cost performance.
