Alli-Flex Black Plastic

Alli-Flex from Allied Plastic Supply is a soft black, flexible plastic used for prosthetic liners. A cost-effective alternative to black Northvane, Alli-Flex is easy to clean and resists staining. A benefit of a black liner is its ability to mask evidence of bodily fluids that can cause color changes on lighter plastics. Alli-Flex bonds well to itself and has excellent thermoforming capabilities; it should be heated to a temperature between 325°F and 350°F. The material’s properties include an ultimate tensile strength of 1520 psi, ultimate tensile elongation of 750%, and a shore A hardness of 84. Available in 1/2-inch thickness.
