“…As for the presence of damaged microspheres, photomicrographs revealed that the TS1 and TS5 systems showed the most pronounced existence of glass sediments originating from HGMs, increasing the matrix contact surface as reported by Hu et al (2013) 28 . Such behavior regarding the physical integrity of the microspheres was already expected, since in addition to the pelletizing of the extruded yarn, this processing through screw configuration offers more severity for the shear stresses, which is the region with the highest concentration of kneading elements 33 .…”

Polymeric syntactic foams are composites made from the mixture of Hollow Glass Microspheres (HGM) and polymer matrices. One of their main characteristics is their low density and the production of these composites using a matrix derived from renewable sources potentiates their development without neglecting sustainability. In this paper , the properties of High Density Polyethylene (HDPE)/HGM syntactic foams containing 1% and 5% w/w HGM and 5% w/w of a compatibilizer are assessed. The composites were prepared by two processing routes: single screw extruder and twin screw extruder. The morphology and mechanical properties (tensile and impact) of the syntactic foams thus manufactured were ascertained. Morphological analysis indicated that matrix/filler adhesion was poor for all samples and that the best HGM dispersions were obtained in twin screw extruded samples. Mechanical properties were affected by the processing route adopted and by the content of hollow glass microspheres added. Elastic modulus, tensile strength and strain were reduced by 20, 10 and 23%, respectively, in systems processed in a twin screw extruder. Impact strength was the exception, with an increase of more than 300%. Higher contents of hollow glass microspheres led to reductions in mechanical strength of the syntactic foams, varying from 5% for the elastic modulus to 50% for strain.

In this study, poly(acrylonitrile-co-butadiene-co-styrene)/hollow glass microspheres (ABS/HGM) composites were prepared by means of a twin-screw extruder. HGM were incorporated at different loadings of 2.5, 5.0, and 7.5 wt.% at the central extruder zone with different types of ABS. The morphological, physical, thermal, rheological and mechanical properties of ABS/HGM composites were investigated. Statistical analysis reveals that high impact ABS addition is significant for improving composites' impact strength. The results also indicated that addition of 5.0 wt.% of HGM along with 5.0 wt.% of powdery ABS at the central extruder zone maintains the HGM integrity while powdery ABS contributes to better filler dispersion in the matrix resulting in light-weight composites having improved mechanical properties.

“…The perfect spherical morphology with smooth surfaces and hollow structures endow HGM excellent dispersion, high flow ability, low density and superior thermal insulation property [1][2][3][4]. Therefore, it is widely used in many areas, such as the aerospace [5], deep-sea exploration [6,7], hydrogen storage [8,9] etc.…”

“…TBT (Tetrabutyl titanate) and PFOTES (1H,1H,2H,2H-perfluorooctyltriethoxysilane) were firstly hydrolyzed and deposited on HGM surface. In this step, TBT was hydrolyzed into Ti(OH) 4 . Following that, the hydrothermal was processed in order to turn amorphous Ti(OH) 4 to crystalline anatase TiO 2 .…”
