Mechanical properties for rubber
Our minerals are excellent reinforcement agents improving the mechanical properties of rubber compounds.
Improving mechanical properties of finished rubber items
Imerys minerals improve the mechanical properties of finished rubber items in most rubber applications. They can be used in association with most elastomers commonly used by the rubber industry.
Our minerals improve:
- Tensile strength
- Compression set
- Cut and tear resistance
- Abrasion resistance
- Crack growth and fatigue resistance
- Thermal and weather aging
Microlamellar ImerFlex® talc, which has a higher surface area at the same fineness as conventional lamellar talc, improves elastomer chain wetting, providing better reinforcement levels than conventional lamellar talcs.
Used as a partial substitution for carbon black, ImerFlex talc improves mechanical properties such as elongation at break and cut and tear resistance of peroxide cured compounds, even at high temperatures.
Fine grade wollastonites such as our Wollastocoat® range with their acicular shape provide excellent reinforcement properties and reduced costs in fluoroelastomer (FKM) seals, gaskets, plugs, o-rings and molded applications.
Natural diatomaceous earths such as our Celtix™ grades are a good choice for replacing precipitated silica to improve compression set in EPDM.
