Hollow glass microspheres have multiple uses, but one of the most prominent is in the rubber industry to make products such as silicone rubber sealants. The major advantage that hollow glass microspheres provide is in terms of reduction in weight which allows for easy application for smooth transportation. PETRA MicroLite glass microsphere provides adequate insulation, durability, and stability which not only aid transportation but other applications as well.
How is it used With Rubber?
In terms of research, it is to be understood that the size of a particle, its capability with regard to bonding, and the load it has in determining strength, resistance, and rigidity in certain composites. Several researches also came to the conclusion that the properties in rubber were significantly enhanced when hollow glass microsphere was incorporated in them. Studies also suggest that when something has viscosity which is low melting in nature than that can be made by using hollow glass microspheres in polyester and epoxy resins.
In another study, the behaviour of hollow glass microspheres was studied in terms of fracture and strength when incorporated in composites such as rubber. The hollow glass microspheres have more strength in comparison to the production of the composite independently. Further, when diverse composites were prepared from hollow glass microspheres, the observation was made that the durability of the material becomes higher when the hollow glass microsphere is high in density in the material during incorporation. In addition, the capacity for absorption of energy of the material increased to about 40% through the use hollow glass microsphere. One of the most important studies was with regard to the dielectric nature of the hollow glass microspheres which were filled with substituting composites and in this regard, it was noted that the consistency increased and losses reduced in terms of dielectric when hollow glass microspheres were added in increased quantity. Further in the context of fracture in terms of hollow glass microsphere, it is noted that the incorporation of the microspheres actually enhanced the flexural modulus and reduced the toughness and strength in terms of fracture.
In terms of silicon rubbers, it is observed that the density and conductivity of these products increase with the addition of hollow glass microspheres. Silicone-induced rubbers are an essential product and the main composition of this product is made of SiOsi bonds. In place of rubber without silicone, silicone-induced rubber proves to have a high resistance to both increase and decrease in temperature, it is resistant to changes in weather, it has enhanced insulation in terms of electricity, and is also resistant to erosion along with the presence of physiological inertia. This sort of rubber is widely utilised in the aerospace industry, electrical products, biomedical industry, power plants, and other such industries. Hollow glass microspheres make for a very suitable filler that is non-metallic in nature. The distinct structure of the hollow glass microsphere allows it to light in terms of weight, have high strength, and provide insulation which allows for them to be used in foam, materials related to aerospace as well as buoyancy.
The hollow microsphere is a very special material that is also inorganic in nature and has very diverse uses. The most distinct benefit of their hollow cavity is that it provides for increased isolation with regard to heat and has a very airy density. Thus, in terms of practical application in the rubber industry, one very important aspect is that of its incorporation in silicone rubber which encompasses as a filler not only intact spheres, but also fractured ones in separate ratios. The use in the rubber industry also suggests that even when the hollow glass microspheres are broken, it rather increased these properties which have been discussed above. PETRA MicroLite GM provides all these characteristics that can be useful in the rubber industry.
