ROYALTUF™ 498 a maleic anhydride grafted EPDM used for increasing low-temperature impact resistance of polyamides. It is ideal for recycled polyamide compounds.
ROYALTUF™ 498 is a maleic anhydride grafted EPDM impact modifier for polyamides. Imparts "super tough" properties to nylon when used at a 20% load rate. As a result of having an amorphous backbone, ROYALTUF™ 498 improves impact resistance when used at temperatures as low as -46 °C.
Appearance: Off-white rubbery pellet
EPDM Backbone: Amorphous elastomer
Mooney Viscosity @ 125 °C: 30
Maleic Anhydride Content: 0.8-1.2%
Density @ 23 °C: 0.87 g/cm³
Bulk Density @ 23 °C: 0.6 g/cm³
Glass Transition Temperature: -46 °C
Primary Chemistry: Maleic Anhydride Modified EPDM Terpolymer
Food contact approvals
Excellent impact resistance in nylon at temperatures as low as -40°C
Poor strength and impact resistance of nylons and polyamide compounds
at low and sub-zero temperatures
Difficulties achieving the desired toughness of nylon compounds for use in low-temperature applications
