Rubber

Our Science & Technology (S&T) experts have years of experience in the use of mineral extenders in Polymer systems. In fact, many of our specialists have firsthand experience of your specific market and needs having worked in the industry before joining our ranks. Good understanding of your market segment is vital to boosting your performance.

Every year we perform hundreds of formulation studies.

Our Polymers team has in-depth knowledge of how our minerals interact in your applications. By matching exactly the right mineral to your requirements and optimizing parameters such as particle size, shape, packing, crystal micro-structure, color, and hardness, we can meet your exact formulation requirements, saving you time and bringing added performance to your end products.

Our Applications Laboratories are equipped with a full range of analytical and Polymer-specific equipment enabling us to spearhead applications innovation as well as providing you with bespoke formulation services and technical support.

Our S&T managers can also study your production processes to ensure best use and handling of our minerals in your systems.

Please contact your regional Rubber Expert to find out how we can help.

Since their inception over twenty five years ago, our state-of-the-art Technology Centers in San José (USA) and Toulouse (France) have built up a solid reputation for helping our customers develop new formulations.

Imerys minerals are naturally occurring minerals that are simply ground to achieve a specific particle distribution size. 

Our Mistron^® and Mistron^® Vapor talcs make cost-effective, LEI alternatives to carbon black where they:

• Enhance barrier properties
• Lower Mooney viscosity
• Improve tensile strength
• Prevent scorch

The GHG emissions associated with producing products like Mistron^® are ten times lower than those associated with petroleum-based carbon black.

Wollastonites, such as our Wollastocoat^® grades, are ideal for replacing carbon black in fluoroelastomer O-ring and gasket applications where they improv compression set and curing time. 

Our high aspect ratio Mistron^® HAR talc improves air retention in tires by up to 50% making it ideal for low-rolling-resistance (LRR) tires. Stronger and less permeable rubber allows producers to make thinner, lighter parts-which are the building blocks of today's more fuel-efficient cars. 

Using new Mistron^® HAR in your tire compounds means:

• Lighter tires
• Lower rolling resistance (LRR)
• Lower fuel consumption
• Lower CO₂ emissions
• Better fuel efficiency ratings
