There are three main materials used to make prosthetic chambers: resin, PP sheet and carbon fiber. Each receiving cavity has different characteristics.

PP sheet

PP sheet is a kind of semi-crystalline material. It is harder than PE and has a higher melting point, has superior chemical resistance, heat resistance and impact resistance, non-toxic, tasteless is currently one of the most in line with the requirements of environmental protection engineering plastics.

To make it, a prosthetic technician heats the plate and sets it over a plaster cast, which is usually white in color.

Resinous material

Resin material is the most mainstream material for prosthetic cavity at present, its hardness is higher than plate, lighter weight. It can be divided into domestic resin and imported resin, and the color is mostly flesh color. Pigment or patterned gauze can also be added to make personalized accepting cavity.

The resin receiving chamber is made by pumping the chamber in the state of resin liquefaction. It has space for fine tuning. When fine tuning is needed, it can be heated with a hot air gun and then cooled and hardened. Resin accepting cavity is divided into inner cavity and outer cavity. When connecting parts, it is directly formed with the outer cavity. The inside of the cavity is smooth, and the bottom can be directly adsorbed stump.

Carbon fiber

Carbon fiber is compact, strong, durable, flexible and resistant to corrosion. A strategic new material with excellent properties, less than a quarter of the density of steel, but 5-7 times the strength of steel.

By adding carbon fiber cloth to resin material, the overall hardness and weight of carbon fiber receiving cavity made are better than resin, with the advantages of light weight and high durability. But once the cavity is made, it cannot be fine-tuned.

Xiamen LFT composite plastic Co.,ltd

Long carbon fiber reinforced composites offer significant weight savings and provide optimum strength and stiffness properties in reinforced thermoplastics. The excellent mechanical properties of long carbon fiber reinforced composites make it an ideal replacement for metals. Combined with the design and manufacturing advantages of injection molded thermoplastics, long carbon fiber composite simplify the re-imagining of components and equipment with demanding performance requirements. Its widespread use in aerospace and other advanced industries makes it a "high-tech" perception of consumers - you can use if to market products and create differentiation from competitors.
