1） Resin putty

Resin putty is a commonly used composite material for repairing glass fiber reinforced plastic products, automobiles, ships, and machine tools. Although the name is resin putty, but too high resin content will give putty high viscosity, not easy to smear, paint, use in the actual production process often add calcium carbonate, talcum powder and other fillers to neutralize the viscosity of the putty. Hollow glass beads with light weight, strong adhesion, hardness and other advantages, it can not only optimize the putty in the amount of resin and viscosity, high strength characteristics can also meet the sanding, polishing and other processing needs, so that the resin putty is easier to apply, and is not easy to crack, deformation.

2) Foam block

Synthetic foam blocks are often used as a core material in the rudder, need to meet the high compression, bending strength and dimensional stability at high temperatures and other application requirements. Hollow glass beads are inorganic non-metallic materials, so it has good thermal insulation and heat preservation performance. In addition, the high case strength of hollow glass beads can replace engineering plastics and epoxy resins to enhance the ABS strength of synthetic foam blocks. Most importantly, the extremely low mass of hollow glass beads can greatly compress the weight of foam blocks and rudders.

3) Lightweight GRP core

Similar to synthetic foam blocks, hollow glass beads can be used instead of fiberglass in the manufacture of lightweight GRP cores, which can greatly improve the hardness of the core and reduce the weight of the product, the compressive strength is usually between 28.4MPa and 42.6MPa, and the density is usually maintained between 0.57g/cm3 and 0.67g/cm3. Lightweight GRP cores made with hollow glass beads can be used to manufacture sports equipment, deep water floats or laminated composite panels for vehicles, ships and buildings.

4) Glass Fiber Winding and Pultrusion Processes

Glass fiber winding and pultrusion processes are commonly used in the continuous production of composite linear products, which require both longitudinal and transverse strength to meet the requirements of different mechanical properties of products. Hollow glass beads can replace the resin or glass fiber in the extrusion process, and play a role in improving the impact strength of the composite material and improving the mechanical properties of the product, giving the composite material more dielectric insulation properties. At the same time, the excellent fluidity of hollow glass beads can play a certain lubricating effect in the glass fiber winding and pultrusion process, and improve the pultrusion speed by at least 25%.

5) Flake or agglomerate molding compounds

Flake or agglomerated molding compound can be used instead of ordinary nylon material to fill the fuse box of automobile, which requires both flame retardant and dielectric properties. Hollow glass beads belong to the glass material, at the same time has a very low thermal conductivity and high quality insulating properties, commonly used in filling thermal insulation products or insulating products. Hollow glass beads are therefore perfectly suited for sheet or agglomerate molding applications, enabling the manufacture of insulation panels that meet specific requirements and can reduce the weight of the molded product by an additional 25% to 35%.
