In this study, the physico-chemical properties of high performance polyurethane synthesized from poly propylene glycol (PPG) in comparison with a combination of PPG and castor oil, is studied using the in-situ polymerization technique. The variations in properties of both types of polyurethanes are evaluated by Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), X-ray diffraction (XRD) and the thermogravimetric analysis (TGA) technique. Tensile strength properties were investigated by film tensile testing equipment. The results indicated the presence of large -CH stretching in the castor oil mixed polyurethane with a larger oxidative thermal stability over pure PPG polyurethanes. The tensile properties were found to be almost comparable in pure and mixed polymers, signifying the usage of mixed polymers in the future to overcome the environmental and economic crisis in polyurethane synthesis.

“…TPU possesses a myriad of favorable properties: excellent physical properties, chemical resistance, abrasion resistance, adhesion characteristics, and ease of processing. Therefore, TPU's applications run the gamut from engineering materials and coatings to adhesives and films 16,17) . Polymer blending has been accepted as an efficient and inexpensive method of polymer property diversification 18,19) .…”

“…To obtain a useful product with a satisfactory level of cohesion, various structural considerations of the blend partners should be considered so as to obtain a blend that may be classified as miscible or mechanically compatible 20) . To date, a considerable amount of literature on polyester blends has been published: PETG/PET, PETG/LCP, PC/ABS, PC/PP, TPU/PVDF, TPU/PP, and TPU/PMMA 10,17,[21][22][23][24][25] . These studies showed that polymer blending was indeed an effective way to improve the mechanical properties of polymers, eventually culminating in a high-performance engineering material.…”

PETG/PC/TPU polymer blend was prepared by mechanical blending. The mechanical properties of modified PETG/PC/TPU blend were characterized using a universal testing machine, and results were compared against two commercial thermoplastic products -Erkodur and Biolon. Blending modification improved the properties of PETG/PC/TPU. When blending ratio (wt%) was 70/10/20, PETG/PC/TPU exhibited optimal mechanical properties which exceeded those of Erkodur and Biolon. Tear strength was 50.23 MPa and elongation at break was 155.99%. Stress relaxation rate was 0.0136 N/s after 1 hour, which was significantly slower than Erkodur and Biolon (p<0.05). Water absorption rate was 0.57% after 2 weeks, which was significantly lower than Erkodur and Biolon (p<0.05).

“…One of the most important factors affecting the properties of TPU is that it has block structures that consist of soft and hard blocks, and there is thought to be a clear microphase disjunction taking place inside of them. In providing a network of physical junctions in TPU, the decisive role is played by hydrogen bonds, which are simply broken down and reallocated depending on thermal effects or owing to modifications [83][84][85]. The hydrogen bonds' distribution influences the extent of microsegregation in TPU and the set of properties that are typical for this type of material.…”

Abstract:One of the most essential components of the fused deposition modeling (FDM) additive manufacturing (AM) process is the build plate, the surface upon which the part is constructed. These are typically made from aluminum or glass, but there are clear disadvantages to both and restrictions on which materials can be processed on them successfully. This study examined the suitability of heated aluminum-polycarbonate (AL-PC) composite print beds for FDM, looking particularly at the mechanical properties, thermal behavior, deformation behavior, bonding strength with deposited material, printing quality, and range of material usability. Theoretical examination and physical experiments were performed for each of these areas; the results were compared to similar experiments done using heated aluminum and aluminum-glass print beds. Ten distinct materials (ABS, PLA, PET, HIPS, PC, TPU, PVA, nylon, metal PLA, and carbon-fiber PLA) were tested for printing performance. The use of a heated AL-PC print bed was found to be a practical option for most of the materials, particularly ABS and TPU, which are often challenging to process using traditional print bed types. Generally, the results were found to be equivalent to or superior to tempered glass and superior to standard aluminum build plates in terms of printing capability.
