Royaltherm® is a silicone-modified EPDM. It is ideally suited for high-temperature applications. Compared to normal EPDM, Royaltherm® provides better heat and weather resistance. Compared to silicone, it provides better tensile strength, flex fatigue resistance and other mechanical properties. It exhibits good electrical properties in moist conditions and, unlike silicone, retains physical properties even in hermetically sealed environments.

Royaltherm® 1411A
  • Product Families:EP Rubbers (EPDM), Silicone Elastomers, Specialty Elastomers
  • Chemical Family:Ethylene-Propylene Copolymers (EPR), Silicones, Polyolefins
  • Polymer Name:Silicone Elastomer, Ethylene Propylene Diene Terpolymer (EPDM)
Royaltherm 1411A is a modified EPDM with a special silicone rubber. Royaltherm 1411A is supplied as a base compound that can be vulcanized with peroxides or sulfur/accelerator systems. Royaltherm 1411A is 30 - 40 Durometer when vulcanized with 1.8 phr of dicumyl peroxide. It can be blended with Royaltherm 1721 for intermediate hardness applications. Royaltherm 1411A is recommended for applications that require lower tensile strength than Royaltherm 1721. Royaltherm 1411A is also recommended for applications that require retention of mechanical strength at elevated temperatures, weather and moisture resistance, electrical stability and compression recovery at low temperatures.
