Application

Polymers

Glassflake provides reinforcement to a wide range of plastics, from commodity products such as food packaging, through to high performance plastics for the medical, electronics and automotive sectors. The morphology of the flake offers excellent isotropic reinforcement to a range of systems, due to its high surface area. The neutral mass colour tone, allows the flake to be used in a range of systems where aesthetics are key.

癞子斗地主Glassflakes are high aspect ratio platelets that impart isotropic reinforcement in contrast to fibres which typically give anisotropic reinforcement. This isotropic reinforcement is evidenced under a number of test regimes; from warpage evaluations to heat deflection temperature values. This change to the composite behaviour under strain is due to the high surface area of the glassflake used, restricting the free movement of polymer chains over the surface of the flakes. As glass flakes are synthetic with a controlled composition they have very low impurities - as such they are suitable for inclusion in materials for food contact and medical and dental applications.

癞子斗地主All glassflake is available with silane surface treatments or 'sizings' - these are especially important for use in plastics where this aids in both the manufacturing process and end application. Similarly to other glass and mineral fillers, organo-functional silanes are used, providing a silicon end to bind to the glass surface and organic functional group to interact with the surrounding polymer chains. 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. E glassflake is also available in an agglomerated form, using an epoxy resinous binder to facilitate easier processing and handling.
