Segmentation, Lamination and Post Processing of Amorphous Thermoplastic Urethane
Introduction
Segmenting and lamination process technologies result in varied proportions of modulus exhibited at specific axial and or circumferential designations. This is possible due to specific thermal process parameters and tooling with respect to materials used.
Materials
Products can exhibit superior physical characteristics due to their synergy of optimized processes for specificmaterials, which results in an even distribution of molecular architecture. This is especially obvious when comparing stress / strain characteristics of an as extruded or injection molded TPU to one that has been processed in accordance with optimized time and temperature parameters. Additionally, an amorphous composition of hard and soft segment TPU’s will exhibit significant predictable end product performance compared to TPE’s consisting of crystalline matrices, see Figures 2.0 that unfortunately, a broad time and temperature matrix can not establish.
Technology
Products can exhibit infinite variability’s of stiffness, torque, durometer, radiopacity, and volumetric change where they are required. The process responsible for these results is focused specific time and temperature parameters corresponding to thermoplastic properties of specific polymers used.
