About Us

Glassflake is a pioneer in the glass flake industry, being the first to produce flakes utilising the advanced 'spun method' often referred to as rotary process technology.

What is glass flake

The term 'glass flake', which is a platelet material, of high aspect ratio, refers to material that can be manufactured using a variety of methods and available from a number of sources.

The Glassflake range of products has a number of unique features. For example, the aspect ratio of individual flakes can be altered by controlling both the flake thickness (7µm to 100nm) and the flake diameter (10µm to 300µm average). Glassflake has been utilised in a diverse range of applications, bringing improvements to reinforcement, barrier and thermal properties in finished products.

Glass flake was first used in the late 1950s for reinforcement of polyesters, they were then quickly adopted into the anti-corrosive coatings sector as an in-situ barrier, only later finding their way into the effect pigments sector as a substrate and into wider use in polymers to improve mechanical, barrier and thermal properties. Glassflake Ltd was formed in 1987 as a result of extensive research and development to create a technically superior type of glass flake than the one available in the marketplace at that time, specifically for the coatings market. Innovations in production and glass technology were required to achieve these products. The Glassflake Group introduced Glassflake with lower average thicknesses and significantly reduced deviation as well as engineering glass compositions.
