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.

Who We Are

The Glassflake team is made up of a diverse group of material scientists, chemists and engineers, this mix of skills has allowed the company to develop an unrivalled range of standard products and to deliver innovative ideas to solve customer problems.

What We Do

Glassflake uses an innovative manufacturing process which has enabled accurate control of glass composition and the production of thinner flake (as low as 100nm) with uniform thickness and exceptional consistency. Innovation is at the core of what we do, both in developing new glassflake products as well as pushing the boundaries of applications for glassflake.

Committed To Quality

We are committed to:

Working with customers to ensure that our products and services fully meet their requirements and expectations.

Continually improving customer satisfaction.

Developing people and ensuring that all employees are highly trained, motivated and equipped.

Our Company supports these commitments by the use of a Quality Management System that is continually reviewed to assess its effectiveness and opportunities for further improvement.

Glassflake Ltd is accredited to quality management system
ISO 9001:2015.

What is GlassFlake

Glassflake is a platelet material, of high aspect ratio. 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.

Timeline

  • 1980 - Concept of novel glass flake rotary production
  • 1983 - First glass flakes produced on new process

  • 2013 - Launch of sub 1-micron glassflake as the 'next generation' of effect pigment substrate
  • 2015 - Sibelco UK Ltd becomes significant share holder

Glassflake 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 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. Glassflake introduced glassflake with lower average thicknesses and significantly reduced deviation as well as engineering glass compositions.
