Sound Absorption of Solid-State PETG Foams

Porous, Cellular and Microcellular Materials, 1998
Abstract The sound absorption characteristics of PETG foams have been investigated experimentally. The normal incidence sound absorption coefficient was measured using an impedance tube designed according to ASTM 1050-90. The effect of both the cell size and the density of the foam on the absorption coefficient were investigated.

Photodegradation response of PP and PETG composites

Journal of Composite Materials
This work revisits the accelerated weathering behavior of polymer composites, with a particular focus on the differential responses observed between their surface and core regions. For this purpose, two distinct long glass fiber reinforced polymer (FRP) systems are chosen with polypropylene (PP) and polyethylene terephthalate with glycol modification ...

Transesterification reaction of polyarylate and copolyester (PETG) blends

Polymer Engineering & Science, 1997
AbstractTransesterification reactions between polyarylate (PAr) and a copolyester (PETG) have been investigated by proton nuclear magnetic resonance (NMR), Fourier‐transform infrared spectroscopy (FTIR), and differential scanning calorimetry. Blends of PAr and PETG were prepared by melt mixing and solution‐casting with weight fractions of PAr in the ...

Robust superhydrophobicity by candle soot deposition on plasma-treated PETG

Surface Innovations, 2015
Surface etching was achieved by exposing poly(ethylene glycol-co-1,3/1,4 cyclohexanedimethanol terephthalate) (PETG) samples to oxygen plasma produced in reactive-ion etching configuration of a radiofrequency plasma device. The surface modifications on the sample surfaces were determined by employing water contact angle measurements and profilometry ...
