Brands in EP Rubbers (EPDM)

KRAIBURG continually tries to set new standards in technology, quality, manufacturing, delivery performance, customer relations and service. Highly customized and cost-effective solutions far exceed the current standards. KRAIBURG is the leading specialist for the development and manufacture of rubber and silicone compounds that fulfill the most stringent requirements.

RoyalEdge® EPDM is used in a wide variety of elastomeric applications that require superior heat, ozone and chemical resistance, excellent long term aging and outstanding weathering. RoyalEdge® EPDM products are terpolymers of ethylene, propylene and a non-conjugated diene (ENB or DCPD) that vary in viscosity, ethylene/propylene ratio, and type and amount of diene according to desired processability and end properties.

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.

Ethylene Propylene Diene Rubber (EPDM) is a copolymer manufactured from ethylene, propylene, and a small number of diene monomers. A small number of diene monomers form unsaturated groups pendant from the main saturated chain. These diene monomers provide cross-linking sites that allow EPDM to be vulcanized.

Royalene® EPDM is used in a wide variety of elastomeric applications that require superior heat, ozone and chemical resistance, excellent long term aging and outstanding weathering. Royalene® applications include automotive, industrial and consumer hoses, weatherseals, molded goods, wire and cable insulations, window profiles, roof sheeting, thermoplastic elastomers, and viscosity modifiers for lubricants.

SuperOhm® peroxide crosslinkable EPR compounds are designed for high temperature stability and superior electrical performance.

Petro Rabigh produces 75 KTA of EPR made by the polymerization of ethylene, propylene and ethylidene norbornene (ENB) used as a third monomer.EPR is widely applied to sealing products (O-ring, packing) electrical equipment and automotive part

A range of metal detectable and X-ray detectable elastomer compounds designed specifically to meet the stringent demands of the pharmaceutical and food processing industries. The Detectaseal® range includes FDA compliant grades of EPDM, Nitrile, Silicone and Fluorocarbon (FKM) compounds, plus USP Class VI certification for Silicone. All materials in the Detectaseal® range are free from animal derived ingredients (ADI-free) and conform to EU regulations EC1935/2004 and EC2023/2006. Available in blue and black, Detectaseal® O-rings have been tested and proven in use at leading pharmaceutical and food manufacturing plants. Fragments of Detectaseal® as small as 2mm can be identified by x-ray and in-line metal detection equipment in process lines.

AquaGraft® moisture curable systems allow customers to crosslink polymer systems without investing in expensive curing processes.
