Polymer is a very broad term that encompassed a large amount of materials. The world “polymer” refers to materials that are composed of repeating identical molecules.

The type of molecule, the length of the chain, the amount of cross-linking, the presence of various chemical groups – all affect the behavior as well as chemical and physical properties of the material.

Many different polymers can be used as raw materials for hollow glass microspheres. The most common polymer microspheres are made from polyethylene, polystyrene, and poly(methyl methacrylate).

The goal of the study was to find a cost-effective composition of a particle reinforced composite that is light in weight but has sufficient mechanical properties. The matrix of the particulate composite is unsaturated polyester resin that is reinforced with alumina trihydrate particles. Part of the alumina trihydrate proportion was replaced with hollow glass microspheres to reduce weight and save costs.

In order to find out the influence of the light filler on the physical and mechanical properties of composites, materials with different percentages of the light filler were prepared. Test specimens were cut from moulded sheets that were fabricated with vacuum assisted extruder. Tensile strength, indentation hardness measured with a Barcol impressor, and density were determined. Based on the experimental data a multi-criteria optimization problem was formulated and solved to find the optimal design of the material. Artificial neural networks and a hybrid genetic algorithm were used.

The optimal solution is given as a Pareto curve to represent the distinction between the density and selected mechanical properties of the composite material. The composite material filled with 6% hollow glass microspheres showed 3% loss in the tensile strength and 26% loss in the surface hardness compared to the composition without the filler. The weight decreased by 13% compared with the initial composition. The addition of hollow glass microspheres did not lower the net value of the material, it increased 7%.

This study deals with the hydrostatic strength of hollow glass microspheres composites, commonly known as syntactic foams, using model materials made of 0.15 g/cm³ hollow glass microspheres with 3 types of matrix, two epoxies and one paraffin.

More than 100 model material samples are characterized for that work. The hydrostatic strength of these composite materials is determined in a pressure vessel, which can go up to 100 MPa. Two major parameters are studied: stiffness of the matrix and hollow glass microsphere volume content within the composite material.

The results clearly show that the hydrostatic strength of the syntactic foam can be improved by an increase in matrix stiffness or a reduction in hollow glass microspheres content. Based on experimental data an empirical model with two parameters is proposed to describe the hydrostatic strength of syntactic foam. The relevance of the model is discussed.

Glass used to be called colored glass because of its twists and turns. When the light passes through the glass, the refracted light is very beautiful. We all know a little about the use of glass, such as cups, windows, decorations, etc. Because of the strong plasticity of glass, it can be made as it is.

Do you know about glass beads? This is a new material that has been developed slowly in recent years. Please see below for the specific use of glass beads.

Use of glass beads:

1、 There are three types of reflective glass beads for roads:

1. It is used for surface spreading during normal temperature and hot melt standard construction, which has a strong reflective effect!

2. As a premixed material, it is premixed in the coating during the production of hot-melt road coating, which can ensure that the marking will reflect light for a long time within its service life

3. This kind of glass bead should be used to sprinkle glass bead on the surface of normal temperature solvent paint marking.

2、 Glass beads for industrial use

1. Purpose

(2) It will not contaminate the processed metal.

(3) It can speed up the cleaning and restore the original cleanliness and finish of the processing materials.

3、 Other applications

1. Glass beads have been widely used in artificial agate, marble, glass fiber reinforced plastic bowling ball and other composite materials as well as high-grade thermal insulation coatings, which can significantly reduce the weight of products and have good thermal insulation effect.

2. Glass bead is a sensitizer with excellent performance for civil emulsion explosives, which can significantly improve the initiation performance of emulsion explosives and extend the storage period. In addition, hollow glass beads can also be used to increase the volume of putty, improve the grinding performance, and improve the acid and alkali resistance.

It can be seen from the above that the use of glass beads is very extensive. Glass beads are a new type of material. With its slow development, it is believed that glass beads will have more and more uses and will be used in more industries. This is to be explored slowly. And glass beads are also used in zebra crossings on urban traffic roads. Under the sun or light, there will be some light flashing to remind everyone to be careful. As for the future use of glass beads, let’s wait quietly.

Nowadays, with the continuous improvement of domestic fire safety requirements, the development of materials with better thermal insulation and flame retardant performance is of great significance to modern building energy conservation.

Hollow glass microspheres modified polyurethane sponge (PU-HGM) with enhanced flame retardancy is prepared by dipping hollow glass microsphere onto PU sponge through polydimethylsiloxane. The PU-HGM sponge exhibits porous network structure with rich micron sized pores, as well as the hollow glass microsphere with closed hollow spherical structure endow the prepared PU-HGM better thermal insulation performance, and the thermal conductivity is 0.050 W m−1 K−1.

Besides, the PU-HGM maintains excellent elasticity of PU sponge, and shows strong mechanical strength, the stress of PU-HGM sponge was as high as 882 kPa at 70% strain after 3 cycles. More importantly, compared with pure PU sponge, the PU-HGM shows excellent flame retardancy. It keeps its original shape after combustion, and no obvious flame was observed on the surface of PU-HGM sponge.

Thus, combined with its high mechanical strength, low material cost, simple and scalable preparation method, the as-prepared PU-HGM sponge shows great potential for application in the field of heat insulation and flame retardant.
