ROYALTHERM® 1721
ROYALTHERM 1721 a modified EPDM with a special silicone rubber. ROYALTHERM is
supplied as a base compound that can be vulcanized with peroxides or sulfur/accelerator
systems. ROYALTHERM 1721 is 55 - 65 Durometer when vulcanized with 1.8 phr of dicumyl
peroxide. It can be blended with 1421 for intermediate hardness applications.
ROYALTHERM 1721 is recommended for applications that require higher tensile strength than
1421. ROYALTHERM 1721 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. It has superior overall heat resistance to
1711.
