TPU/Mica Composites Prepared in Torque Rheometer: Processability, Mechanical Properties and Morphology

Abstract

This work is concerned with the preparation of thermoplastic polyurethane elastomer (TPU) composites with mica, and their characterization as for processability, mechanical and thermal properties and morphology behavior. The amount of added mica varied from 0 to 20 phr and the results showed few interactions between mica and the polymer matrix. Processability is facilitated by the increasing amount of mica but TPU upon strain crystallizability, as well as T g , decrease with the increase in mica content. The main interest in using mica is the evaluation of a low cost mineral as a reinforcing material for the engineering polymer TPU.

Improved crystallizability and processability of ultra high molecular weight polyethylene modified by poly(amido amine) dendrimers

“…The steady‐state torque is a measure of the melt viscosity depending on the morphology, molecular weight, composition, etc. . The representative melt viscosities of blends were calculated from the torque values in Table and the following Eq.…”

“…FT‐IR measurements were used to determine the distribution of the dendritic modifier in the UHMWPE matrix as described previously . FT‐IR spectra of samples were recorded by the KBr pellet testing techniques using a Nicolet 6700 spectrometer (ThermoElectron Corp.), and the spectra of core and skin layers from the mixtures were collected in attenuated total reflectance (ATP) mode in the range of 1,000 to 2,000 cm −1 with a resolution of 4 cm −1 .…”

“…Thus, a certain inorganic number of hybrids and organic nanocomposites were cited in the literature. [4][5][6][7][8][9][10] The matter is intended for a large variety of fields of application such as adhesives, chromatography, protein immobilization, colloidal stabilization, medicine, dentistry, and beauty products.…”
