A myriad of benefits

Polymers

Advantages

Thermoplastic polymers often require such properties as resistance to permeation, dimensional stability, surface hardness, mechanical stiffness, wear and abrasion resistance which can be improved by the incorporation of fillers into the formulation. Glass flakes are high aspect ratio platelets that impart isotropic reinforcement in contrast to fibres which typically give anisotropic reinforcement.

As glass flakes are synthetic with a controlled composition they have very low impurities in contrast to natural reinforcements.

 

What type of flake

We offer the following types of glass which can be used for polymer reinforcement:

ECR Glassflake

C type Glassflake

E type Glassflake

E glass provides enhanced mechanical properties and, in contrast to ECR or C types of glass, does not have any potential adverse effects on amorphous type of polymers. For further info please contact us

Surface treatment

We offer our glass flakes with the option of surface treatment with one of four silane types listed below which in turn ensures a wide range of functionality.

  • Amino
  • Vinyl
  • Epoxy
  • Acrylic

 

The silane is readily bonded to the glass flake surface aiding wet out, and facilitates dispersion in the polymer. The effect on physical properties will be determined by the degree of interaction between the silane, glass flake and polymer.
