Construction Chemicals

The FRILITE® Group differentiates between construction materials (give buildings basic shape and structure) and construction chemicals (used for connection, protection, sealing, etc.). As construction chemical products are mainly used in thin layers focusing on shape, mechanical strength and weight saving, the finest grades of FRILITE® hollow microspheres are the best choice. Already a relatively low mass fraction in a formulation can make a huge difference. The FRILITE® Group, as one of the few suppliers of hollow mineral microspheres, offers different types and grades (e.g. d10 and d90 values) to formulators in order to meet all standard requirements. The microspheres can also be produced with Topcut.

Construction Materials

Construction materials are one of the largest and most important areas of application for the FRILITE® P-Series. Conventionally expanded perlite has been used in construction materials for many years because of weight reduction or insulation purposes. However, conventionally expanded perlite never became widely accepted in construction materials due to the sensitivity of the material to mechanical stress in the mixing and applying processes and because of its undesirable absorbency. The FRILITE® P-Series, however, offers all these needed characteristics and more thanks to their glazed, closed-cell surface.

Foundry and Refractory

As FRILITE® cenospheres are products of high temperature processes (actually a by-product of the coal combustion process in power plants at up to 1500°C), it is obvious that FRILITE® cenospheres can withstand extremely demanding conditions in high temperatures applications like in refractory materials and especially in the steel and iron foundry industry. It is a combination of the many positive features that make FRILITE® cenospheres so beneficial in all formulas of precast shapes (like bricks, castables, feeders and risers) for these high temperature applications.

FRILITE® E-Series

The FRILITE® E-Series cenospheres have an Al2O3 content between 34-39% and Fe2O3 contents of typically lower than 2%, which leads to an outstanding temperature resistance of over 1400°C. They can be easily recognized by their white to off-white colour. 

The FRILITE® E-Series cenospheres are available in sub grades between 5-600 microns and a bulk density of about 400kg/m³, specific gravity typically reaching from 0,7-0,85g/cm³ and featuring 90% survival rates at >3000 psi.

Applications

  • Foundry and refractory
  • Caulks, sealants, putties and adhesives

Standard Grades

  • F500E
  • F300E

FRILITE® G-Series

The FRILITE® G-Series cenospheres have an Al2O3 content between 26-32%, which leads to good temperature resistance of over 1150°C. They are recognizable by their off-white to grey colour. 

The FRILITE® G-Series cenospheres are available in sub grades between 5-500 microns and a bulk density of about 400kg/m³, specific gravity typically reaching from 0,7-0,85g/cm³ and featuring up to 90% survival rates at >3000 psi.

Applications

  • Foundry and refractory
  • Caulks, sealants, putties and adhesives

FRILITE® P-Series

The FRILITE® P-Series are tiny hollow spheres made from natural occurring sand. The special production process does not use any fossil fuels and is simply based on a physical shape change, without the involvement of any chemicals, resulting in an environmentally neutral product.

The FRILITE® P-Series spheres are available in sub grades between 75-800 microns and bulk densities reaching from 80-600kg/m³.

Applications

  • Plaster and dry mortar
  • Lightweight concrete
  • Lightweight panels
  • Insulation coatings
  • Sound dampening systems

FRILITE® W-Series

The FRILITE® W-Series cenospheres have an Al2O3 content between 30-40% and Fe2O3 contents of typically lower than 2%, which leads to an outstanding temperature resistance of over 1400°C. They are easily recognized by their white to off-white colour. 

The FRILITE® W-Series cenospheres are available in sub grades between 5-500 microns and a bulk density of about 400kg/m³, specific gravity typically reaching from 0,7-0,85g/cm³ and featuring 90% survival rates at >3000 psi.

Applications

  • Foundry and refractory
  • Paints and coatings
