As a feather weight, this additive is extremely light yet has a solid core. Our silica (SiO₂) microspheres reduce the weight of plastics, composites, rubbers, textiles…

The hollow sphere reduces the density of your polymeric material. Our product has a density as low 0.1 g/ml. That is 10 X lighter than water.

Adding silica to any type of plastic (polyolefin, nylon, polyvinyl) or resin (phenolic, vynilic, epoxy, polyester)  increases the mechanical performance of the final material.

It increases:

• Tensile (Strength & Modulus)
• Impact
• Hardness
• Toughness
• Abrasion
• Stiffness (rigidity)

Our microcapsules are hollow silica particles. They act as an air bubble with a hard core of silica.

The capsule has good insulation properties:

• Thermal
• Electrical
• Sound

Silica (SiO2) additives are known to increase fire resistance and lower the smoke.

• Fire resistant: Hollow silica capsules are stable in high temperatures (> 1500C)
• Low smoke: The additive is non-toxic and has low smoke below 1500C.

Being  extremely light weight, the addition of our silica (SiO2) microcapsules to polymer materials can help to save money  on transport.

Also, the density reduction offers an eco-friendly product with greenhouse gas (GHG) reductions. It has a huge environmental impact for the transportation industry.

The additives (silica capsules)  can slow down polymer degradation caused by UV and heat. Other properties like anti-blocking, anti-fogging and nucleating effects can also be obtained by incorporating our silica microcapsules into polymer material.

Materium additives act as:

• Light stabilizer
• Heat stabilizer
• Anti blocking agent
• Anti fogging agent
• Nucleating agent

As an amorphous silica, our hollow microcapsules are non-toxic. Thereby, blended into a polymer or composite matrix, it could be used in transportation or food applications. Moreover, it is an eco-friendly product.

The surface activation or functionalization can allow :

Chemical species (Vinyl, epoxy, amino…)
Applications: Better adhesion to polymer matrices, improves the fracture toughness, do not impact visual aspect and mixing process.

Carbon allotropes (Graphene, Carbon nanotubes…)
Applications: Highly thermal conductive material (semiconductors), purification /filtration, etc.

Biological species (proteins, DNA…)
Applications: Biosensor

Metals (Al, Pt, Ti, Fe…)
Applications: Catalysts, solar cells, etc

We can be customized to your specific needs
