ROYALTUF™ 527 is a maleic anhydride–grafted EPDM impact modifier that is especially useful for improving low-temperature performance in both virgin and recycled polyamides.
ROYALTUF™ 527 is a maleic anhydride–grafted EPDM impact modifier for polyamides. As a result of having an amorphous backbone, ROYALTUF™ 527 improves impact resistance when used at temperatures as low as −47°C. ROYALTUF™ 527 imparts super tough properties to nylon 6; nylon 6,6; and other polyamides when used at a 20% load rate.
