Ash Quartz

This lightly coloured quartz is used either on its own in decorative resin-bound and resin bond systems, or as a base substrate for light coloured pigmentation. Though different in appearance, Ash Quartz has the same hardness and performance characteristics as DKI Quartz (details of which can be found in the DKI Quartz section below). It is available in a variety of particle sizes to cover a range of applications. Visit Boud Minerals online to find out more.

Calcined Bauxite

Bauxite is an extremely hard mineral with high-friction and anti-skid properties, making it suitable for a range of road surfacing applications. Most public sector systems will specify that Calcined Bauxite should be used in their road and pedestrian crossing installations. Bauxite’s natural hardness also makes it ideal for internal and external industrial flooring applications where a hard, long lasting mineral is required to give high-friction, anti-slip performance. Boud can produce pigmented Bauxite in all the main safety colours and in particle sizes from 1.0 – 3.0mm.

Clear Crushed Glass

Crushed glass is commonly used to give a highly decorative finish to external resin-bound, internal and external resin-bonded and terrazzo flooring systems, particularly in situations where a perception of depth is required. Fine, sub 100-micron grades of crushed glass can also be used as general fillers, mainly thanks to their very low oil absorbency. The use of crushed glass brings a recycled element to the system, which has obvious cost and environmental benefits. For more information on crushed glass and its uses as a filler material, please head over to the Boud Minerals website.

ColorMicas

Torginol ColorMicas™ are unique metallic flakes that are used to provide a natural metallic luster to flooring systems. They are derived from a group of sheet silicate minerals known as mica. By separating the distinctive hexagonal atom arrangement of the mica minerals into sheet-like pieces, we’re able to create standardised flake sizes. 

ColorMicas™ are available in six unicolour styles. These can be blended to match virtually any decor. 

To find out more about ColorMicas™, please head over to our website or contact our sales team on 01406 351988. 

Crushed Flint

Crushed flint (derived from blue flints) is a general mineral filler often used as an alternative to quartz or silica sand because of its angular particle shape. It has a glassy surface texture and a hardness of around 7.0 (Mohs). Crushed flint can be supplied in various particle sizes from 0.1mm to 3mm. Technical data can be found on the Boud Minerals website. If you would like to order a sample, please contact our sales office on 01406 351988.

DKI Quartz

DKI Quartz is a light coloured mineral with a naturally rounded particle shape and a hardness rating of 7.0 (Mohs). It forms the main component for many of the dry blends and screed blends that we produce, but can also be supplied as a standalone product; we stock fifteen different particle grades as standard. Special mixes are made to order.

DKI Quartz is washed, dried and processed to meet various continental grade specifications (this is particularly important where the system specifies a particle grading with a tight tolerance). You can order a sample by calling our sales team on 01406 351988.

Dry Liquids

Dry Liquids is a term applied to liquids that are absorbed onto a carrier. Liquids that are difficult to handle or mix can be supplied in powder form – this makes them easier to store, transfer and dispense. Dry Liquids are usually based on amorphous precipitate silica, which gives activities of around 70%. Standard compositions are:

• Dry Liquid 698 - 70% Quin Guard Etoxyquin (Santoquin) / 30% Precipitated silica
• Dry Liquid DR41 - 70% Lithene AH / 30% Precipitated silica
• Dry Liquid P-027 - 70% Paraplex G25 / 30% Precipitated silica

Other products can be produced on demand. 

Expancel

Expancel ultra-lightweight thermoplastic microspheres are used in a variety of manufacturing applications, including coatings, paper and board, speciality inks, automotive body fillers and much, much more. Expancel can be supplied in Wet Unexpanded (WU), Dry Unexpanded (DU), Wet Expanded (WE) or Dry Expanded (DE) format, or in Masterbatch (MB) form, where microspheres are pre-blended in a carrier to improve dispersion in thermoplastic applications. 

If required, Expancel can be adapted according to the end-user application. It can also be pre-blended with dry materials and re-packed to bespoke unit sizes. To discuss your requirements with a member of the Boud Minerals sales team, please contact us on 01406 351988.

Marble Bianco Carrara

Bianco Carrara is a white marble used predominantly for resin terrazzo systems, resin-bound / resin-bonded systems, general decorative resin systems and plastics. All marble is soft and moist from source; Boud Minerals dries and de-dusts marble as a matter of course. Particle sizes range from powders to fine and coarse chippings – for details on particle size availability, please visit Boud Minerals online. Bianco Carrara has a hardness rating of 3.0 (Mohs).

Marble Pebbles

Marble pebbles are tumbled to achieve a smooth, rounded shape ideal for resin-bound systems and aquatic applications. They are dried, sieved and supplied in a range of particle sizes. Rounded marble pebbles are available in a range of colours, including blue, white, yellow, beige, brown, black, pink, terracotta and green. To order a sample, please get in touch with our sales team on 01406 351988.

Microspheres

A Microsphere is a small, spherical plastic particle consisting of a polymer shell and an encapsulated gas. As the Microsphere is heated, the internal pressure increases and the thermo-plastic shell softens, allowing it to expand in size. A combination of low density and high resiliency makes Microspheres ideal for a range of applications, from synthetic leathers and printing inks to automotive body fillers and fish bait. Expancel and other microsphere products can be manipulated to make handling and workability in the production process a little easier. Get in touch to find out more.

Pigment Masterbatch (Roads)

Masterbatch is a pigment additive that aids in the colouring of road surfaces (in particular cycle lanes, stopping areas, parking areas, roundabout approaches, etc.). It is produced in pellet form and can be poured or screwed into the bitumen mixture to make the colouring application process much more easy and convenient. Pigment Masterbatch is pre-dispersed, which means less of the pigment is actually needed; it is incorporated into the mix very quickly and gives a cost-effective, vibrant colour yield.

Pigmented Crushed Glass

Because glass is a clear substrate, there are no restrictions on what colour it can be. Crushed glass can therefore be pigmented and used for very specific and/or creative designs. Pigmented crushed glass is used to give a highly decorative finish in external resin-bound, internal and external resin-bonded and terrazzo flooring systems. It is also commonly used in aquatics and high-spec designer applications (for example, fashions shoots and film sets) where a very colour-specific product is required. Pigmentation of crushed glass takes place in-house under the observation of a quality management team.

Silicon Carbide

Silicon Carbide is a durable, anti-slip material commonly used in the production of PVC safety flooring, stair treads, loading ramps and other surfaces requiring high-friction characteristics. It benefits from high thermal conductivity and low thermal expansion, and can be integrated into a bespoke formulation blend or distributed on a standalone basis. Silicon Carbide also has a slight sparkle, giving a decorative element to the application. It is generally cleaner, more refined and available in much tighter grading than most abrasive, anti-slip products.

Trans Quartz

Trans Quartz is produced by applying a semi-transparent pigmented coating to quartz, so that the natural variation in the base quartz gives variation to the finish. It is predominantly used in resin-bound systems. The application of the pigmented coating takes place in-house at our facility in Lincolnshire. To find out more, please head over to the Boud Minerals website or contact our sales team on 01406 351988.

White Aluminium Oxide

White Aluminium Oxide is often used to give anti-slip properties to a decorative surface. It does this without detracting from the overall appearance of the surface. As a mineral it is also very hard (9.0 Mohs) and very clean. Aluminium Oxide can be pigmented in bright whites and yellows to improve visibility in areas where safety is essential.
