The TephaFLEX® polymer is a semicrystalline material with a melting point of approximately 0°C and is suitable for processing by all methods used for thermoplastic polymers. The most experience gained to date has been in the production of fibers through conventional melt spinning processes. Both monofilament and multifilament materials have been produced. These fibers can then be further processed using conventional textile processes such as braiding, knitting and weaving. Injection molding and film extrusion have also been used. Typical mechanical properties are shown in the table below. Tepha’s polymer is ductile and does not exhibit brittlefracture characteristics.
Typical mechanical properties of TephaFLEX® P4HB P4HB is also soluble in a number of polar organic solvents such as chloroform, methylene chloride, tetrahydrofuran, and dioxane and so processes involving these solvents may also be used. Processes have been developed that result in very low residual solvent levels. P4HB is not soluble in water, hexanes, ethanol or methanol.
