With the addition of hollow glass microsphere, tensile strength and modulus increased at varying percentage volume fractions, highest tensile strength was at EPT60-5 (66.7 MPa), which is an increase of about 65% compared to the neat epoxy resin and highest tensile modulus at EPT60-4 (4.5 GPa).

Where tensile strength of the Polypropylene increased upon the inclusion of hollow glass microsphere as a result of improved inter-facial adhesion with the matrix before it declined at EPT60-6 due to increased void content caused by the agglomeration and reduced resin content resulting in low bonding and load transfer stability between the filler and the resin. The interfacial strength between the microsphere and the matrix is very important for the syntactic foam composites as it affects its overall tensile strength.

Although, some previous studies reported a decline in the tensile strength by 60-80% as compared to neat epoxy. They stated that the increase in hollow glass microsphere volume fraction reduced the tensile strength because as the volume fraction of the epoxy resin in the material decreased, the strength of the composites also decreased due to higher range of microballoons in the composites structure.

The impact of micro -pearl powder in the plating fluid on chemical silver plating
In order to eliminate the single -quality silver in the middle of the powder, the amount of plating powder is used to reduce the silver content in the plating powder. Figure 6 shows the overall powder of 20%of the AG content and the surface shape of a single powder. Compared with Figure 6 (a) and 4, it can be seen that with the increase of the amount of powder coverage, the single silver from the pink decrease significantly. This is because the larger the loading capacity, the larger the surface area, the more the core of the silver nucleus, which reduces the appearance of silver single. From Figure 6 (b), it can be seen that except for a few silver particles on the surface of the powder, the size is basically about 50 nm, which is related to the increase in the surface area of ​​the powder and the increase in the area of ​​silver -shaped nuclei, which is related to the increase in the number of cores. Because in the same amount of silver analysis, the larger the number of silver cores, the shorter the core of the core, and the result is reduced to the silver particle size plated on the surface.
in conclusion

The chemical silver plating of hollow glass microspheres is prepared to prepare the hollow glass micro beaded powder with a dense and continuous coating layer. The thickness of the coating layer is about 50 nm. Energy characteristics. At the same time, the effect of chemical silver -plated process parameters on the silver -plated silver plating of hollow glass, and found that:
1. By increasing the content of NAOH in the plating solution. Increasing the P field value of the plating liquid can increase the amount of silver analysis in the plating solution, the coating of the micro -bead surface is more dense and continuous, but there is a single -quality silver with free states;
2. Stabilizer can improve the self -decomposition of the plating fluid, but it has little effect on the uniformity and thickness of the coating of the microfin surface. On the contrary, when the amount of stabilizer is too large, it will also cause the unevenness and denseness of the surface covering layer;
3. By adjusting the loading capacity of the hollow glass microsphere, it can adjust the particle size of the surface of the silver particles, control the thickness of the silver -plated layer, and increase the loading capacity at the same time, which can also reduce the phenomenon of self -decomposition.

A novel epoxy resin (EP)/hollow glass microsphere modified composite was successfully prepared.

Studies showed that the water absorption rate of the g-hollow glass microspheres/EP composite is lower than pure hollow glass microspheres/EP and hollow glass microspheres-KH550/EP composites, while the compressive strength of g-hollow glass microspheres/EP composites could be increased.

The enhanced interfacial adhesion between EP and g-hollow glass microspheres played an important role to improve the compatibility of the two components. The g-hollow glass microspheres show little effect on density (relative to hollow glass microspheres) on the g-hollow glass microspheres/EP composites, which can perform better than the hollow glass microspheres/EP composites being used in marine environments.

It was found that the optimal content of 4,4’-diphenylmethane diisocyanate in the epoxy component was 20 wt%.

Hollow glass microspheres have many attractive features as a hydrogen storage medium.

Optically-induced outgassing of hydrogen from glass is significantly faster than conventional heating.

The observation of unusual alanate structures in the form of needle bundles on the interior and exterior surfaces of the spheres following the encapsulation was obtained.

Glass fifiber fabrics/hollow glass microspheres–waterborne polyurethane (WPU) textile composites were prepared using glass fifiber, WPU, and hollow glass microspheres as skeleton material, binder, and insulation fifiller, respectively, to study the effect of hollow glass microspheres on the thermal insulation performance of glass fifiber fabrics.

Scanning electron microscopy, Instron 3367 tensile test instrument, thermal constant analysis, and infrared thermal imaging were used to determine the cross-sectional morphology, mechanical property, thermal conductivity, and thermal insulation property, respectively, of the developed materials.

The results show that the addition of hollow glass microsphere mixed in WPU signifificantly enhanced thermal insulation performance of the textile composite with the reduction of thermal conductivity of 45.2% when the volume ratio of hollow glass microspheres to WPU is 0.8 compared with that of material without hollow glass microsphere.

The composite can achieve the thermal insulation effect with a temperature difference of 17.74 ◦C at the temperature fifield of 70 ◦C. Meanwhile, the tensile strength of the composite is improved from 14.16 to 22.14 MPa. With these results, it is confifirmed that designing hollow glass microspheres is an effective way to develop and enhance the high performance of insulation materials with an obvious lightweight of the bulk density reaching about 50%.

RTP Company announces the availability of specialty compounds containing hollow glass microspheres which reduce part weight, enhance properties and lower part costs in demanding applications.

High loadings of these microspheres, which are manufactured by 3M and known as ScotchliteTM Glass Bubbles, can be added to thermoplastics to reduce overall part weight, and thus per part material costs. Additionally, they can modify polymer characteristics, achieving lower viscosity, improved flow, and reduced shrinkage and warpage.

For example, some compounds containing ScotchliteTM Glass Bubbles can have their specific gravity reduced by as much as 30 percent. The use of glass bubbles also provides more uniform control and reproducibility than other methods typically used for weight reduction, such as foaming agents.

ScotchliteTM Glass Bubbles reduce thermal conductivity and lower dielectric constants of most thermoplastics. Non-combustible and non-porous, the glass bubbles do not absorb moisture. Compounds containing ScotchliteTM Glass Bubbles are available in most engineering resins and easily adapt to common processing methods, including injection molding and extrusion. Applications that can benefit from this weight saving technology exist in the aerospace, automotive, marine, electronic, and medical industries.

In this work, hollow glass microsphere reinforced triglycidyl-p-aminophenol (TGPAP) epoxy composites was prepared and the influence of hollow glass microsphere on mechanical and thermal properties of the composites was investigated.

Mechanical behaviors of the composites with various weight fractions of hollow glass microsphere from 0 to 9% were investigated in terms of impact property at both room temperature (RT) and liquid nitrogen temperature (77 K). The fracture surfaces of undoped epoxy and the composites were examined by scanning electron microscopy (SEM).

The results show that both the impact strength at room temperature and 77 K are all enhanced by the addition of hollow glass microsphere with appropriate contents.

Furthermore, the thermal conductivity and coefficients of thermal expansion of undoped epoxy and hollow glass microsphere/epoxy composites were also investigated from 77 K to room temperature.

It is found that the composites show lower thermal conductivity and coefficient of thermal expansion than undoped epoxy. The results indicate that hollow glass microsphere/epoxy composites are promising cryogenic materials.
