Hollow glass microspheres are also used with plastic and this context brings in all aspects of hollow glass manufacturing, understanding of its physical composition as well as its diverse applications. It further highlights the positive environmental effect of this process and the health & safety procedures associated with this.
When hollow glass microspheres are observed in incorporation with plastic, its applications also include polymers in thermoplastics, adhesives and elastomers. It is used as a very good substitute to a lot of composites and enhances the sustainability of products made with it. A lot of studies after thorough research of the relation between hollow glass microspheres and plastics have come to the understanding that in order to enhance the performance and functionality of plastic processors, designers, as well as any other professional using plastic with the use of hollow glass microspheres, can make their outputs lighter, more durable and stronger along with reducing the need for increased costs and materials in this process. The best method for plastic as well as rubber making processed is by using hollow glass bubbles/balloons. This will synthesize and reflect all the various properties of the hollow glass spheres and be available for multiple ends uses. Glass spheres have a very significant impact on the nature of products in terms of insulation, resistance, structure, durability, thermal conductivity and so on which changes the applications of the products drastically. PETRA MicroLite GM is one of the brands that provide all these benefits and many more with its high performance.
What happens when it’s applied to plastic?
Hollow glass microspheres have very increased strength, it is low in terms of density, it is also resistant to additives made from liquid and it provides durability as well as stability. These microspheres have a cutting edge over other traditional products such as non-uniform mineral fillers or fibres made from glass. The spherical shape of these spheres aid in reducing the level of resin in numerous ends uses. Further, they create a flow through the ball-bearing nature which aids in carrying increased fillers and smoother flow.
How is it made?
These types of plastics are made by melt blending that includes Poly(?-caprolactone) PCL which has hollow glass microspheres incorporated inside them. Further, with the added effect of treatments such as silanization on the hollow glass sphere, there is a difference brought in the properties of the silanized sphere vs. the unsilanized sphere. The analysis with silanization reflects that the dissemination of glass particles in the matrix of polymer in every case of a filer which is good, the silanized hollow glass microsphere showed a matrix adhesion.
In terms of its thermal nature, it is shown that the rate of crystallization is significantly enhanced and the stability also is enhanced as compared to a PCL without hollow glass microspheres. By adding the hollow glass sphere the mechanical nature of the product is altered which leads to an increase in the stiffness of the material. The tensile strength especially enhances quite significantly in comparison to untreated PCL. This behaviour observes by the hollow glass microsphere filled composites is the tensile strength is enhanced and with the addition of a silane agent the matrix adhesion is also improved. Research shows that by incorporating 20% wt. of hollow glass microsphere the density is decreased by about 12% compared to a PCL without microspheres. With plastics the lightweight materials when reduced in density do not lose out on any mechanical properties, it remains intact. PETRA Microlite glass microspheres in this regard are one of the most effective and very affordable glass microspheres which have multiple uses.
In conclusion, PCL combined with hollow glass sphere material is proved to be carried out effectively by a moulding technique which is rotational in nature and can be done by both lab as well as industrial equipment. It improves the characteristics of the PCL and allows for mechanical reinforcement by reducing weight and providing a rather beautiful appearance as well.
