“…Estane thermoplastic polyurethanes (TPUs) are families of poly(ether urethane) and poly(ester urethane) elastomers with excellent abrasion and wear resistance, tensile strength, elongation properties, impact resistance, low-temperature flexibility, and ease of processing. , Estane TPUs are utilized in a wide variety of applications including biomedical applications (e.g., prosthetics, biodegradable implants, and cardiovascular prostheses), water-permeable membranes, coatings and sheathing, , and binders for propellants and plastic-bonded explosives (PBXs). , Estane 5703, a poly(butylene adipate- co -tetramethylene diphenyl-urethane) referred to hereafter simply as Estane, shown in Figure , is a random copolymer of poly(butylene adipate) (PBA) soft segments formed from adipic acid and 1,4-butanediol (BDO) linkages and poly(tetramethylene diphenylmethane−urethane) (PTDU) hard segments formed by polymerization of bis-1,1‘-(methyl phenyl-4-isocyanate) (diphenylmethane diisocyanate or MDI) and BDO. Estane is a major component of the elastomeric binder for various PBXs, including PBX-9501.…”

We have carried out extensive high-level quantum chemistry studies of the geometry, charge distribution, conformational energies, and hydrogen-bonding energies of model compounds for a family of Estane thermoplastic urethanes (TPUs). Upon the basis of these studies, we have parametrized a classical potential for use in atomistic simulations of Estane TPUs that can also be applied directly or with minor extensions to a wide variety of polyesters and polyurethanes.

A selection procedure has been developed to identify suitable commercial materials for use in compliant-layer artificial hip joints. Mechanical requirements, notably hardness and strength, as well as biocompatibility, constituted the specification for the compliant layer. Applying these constraints, candidate materials were identified in a broad range of polymeric material classes. Detailed sourcing and literature searching helped to identify materials appropriate to the application, with suitable mechanical and physical properties, as well as a history of successful clinical use. Some likely materials were identified but were prohibited from further consideration by limited commercial availability. Physical and mechanical characterization together with literature data were used to determine the relative ranking of the candidate materials and through a weighted materials property selection procedure the materials of choice were identified. The linear segmented aromatic polyurethanes, Tecothane 1085 and Estane 5714F1, emerged as the preferred materials.
