and had physical properties typical of thermoplastic elastomers . The liquid crystal properties were strongly related to the interaction between the hard and soft segments of the polyurethane ...
) fragmentation to characterize thermoplastic elastomers . The compounds investigated, which are used in the manufacture of a wide variety of packaging materials, are mainly composed of thermoplastic copolymers ...
Thermoplastic elastomer ethylene/α‐octene co‐polymer (POE) is a special polymer material with both elasticity and thermoplasticity . However, the nonpolarity and low‐tensile strength of POE limit its ...
to transmission in UV range. INTRODUCTIONThermoplastic polyurethane (TPU), a kind of thermoplastic with the mechanical characteristics of rubber, is usually considered as “bridging the gap between rubber ...
Catalytic nitrobenzene reduction is crucial for the synthesis of 4,4-methylene diphenyl diisocyanate, which is used to produce polyurethane foams, thermoplastic elastomers , and adhesives ...
materials, thermoplastics , elastomers , fibres etc. Depending upon the starting materials, both aromatic and aliphatic moieties containing polyurethanes are employed for numerous applications. However, ...
of alternating hard and soft segments. They belong to one of the most versatile types of engineering thermoplastics known as thermoplastic elastomers . As TPUs exhibit many favorable properties, such as high ...
values, iodine values, specific gravities and isocyanate values have been studied. The formation of the polyurethane resins was confirmed by viscosity measurements, and FTIR, UV and 1H NMR spectroscopic ...
