Marble filler

Product information

Our marble powders are some of the purest and brightest on the market.

Not only are our marble powders some of the purest and brightest on the market, but all products in the Marble range are also made using 100% recycled material, meeting ISO 14021.

Portfolio of calcium carbonate fillers

Our Marble range is available in six particle sizes ranging from 8 to 150 microns:

Stock and logistics

All products are available to collect from our Somerset mill in:

• Bulk tankers
• 1000kg bulk bags
• 25kg sacks

We transport the raw material to our mill at Gurney Slade in Somerset, one of the largest of its type in Europe. Here we mill large quantities to very fine tolerances using state-of-the-art air classification systems. The site has over 6,000 tonnes of raw material storage plus 1,000 tonnes of finished product storage in 10 bulk silos.

Our Marble filler benefits

You can use our mineral extenders as a commercially interesting alternative to polymer in several thermoplastic resins. The calcium carbonate content offers a range of benefits:

• Helping to decrease surface energy
• Improving opacity
• Reduce energy
• Improving surface gloss
• Increase output
• Improving thermal conductivity

Applications for marble offcuts

Our portfolio of very white Marble powders provides functional fillers for use in compound formulations where purity and brightness are essential, including:

• Sealants and adhesives
• Plastics
• Paint
• Food
• Pharmaceutical products
• Drilling muds

100% recycled

Not only are our Marble chips some of the purest and brightest in the market, but an audit also confirmed that all products in the Marble filler range are made using 100% recycled material, meeting ISO14021.

Independent auditing concluded that:

• At our Gurney Slade site, we milled the Marble chips in our specialist facilities, and we sell the range in quantities of 1000kg bulk bags or bulk as standard.
• Our product range is made using 100% recycled materials that would otherwise go unused and be wasted.
• No virgin Marble is ever quarried to help produce our Marble powder range.
• We source all marble in the range of the Carrara region of Northern Italy.
• Every week we produce large volumes of marble offcuts as part of this cutting process.
• Offcuts are taken to a processing site in Italy, where they are:
  • washed,
  • sorted,
  • crushed.
• At all times, we monitor and check the marble to prevent any contamination.

Applications

Our high-purity Marble filler is used across multiple industries for its functional and aesthetic properties. Some key applications include:

Sealants & adhesives

• Used in sealants and adhesives to enhance consistency and improve workability.
• Provides better durability and stability in construction and industrial bonding applications.

Plastics

• Incorporated into plastic formulations to improve texture, reduce weight, and enhance mechanical properties.
• Helps achieve a smoother finish and increases product durability in polymer-based applications.

Paints & coatings

• Added to paints and coatings to improve opacity and achieve a uniform, high-quality finish.
• Enhances the application properties and contributes to cost reduction in formulations.

Food & pharmaceuticals

• Used as a food-grade filler in dietary supplements and pharmaceutical formulations.
• Ensures purity and consistency in tablets, powders, and other ingestible products.

Drilling muds

• Applied in oil and gas drilling muds to control density and improve lubrication.
• Helps reduce fluid loss and maintain stability in drilling operations.
