Overview
PARALOID™ EXL 2691J is a (MBS) impact modifier that offers performance benefits for engineering resins by enhancing mechanical performance. As a core shell structure based on butadiene rubber with a defined particle size, does not influence compounding under normal process conditions. PARALOID™ EXL 2691J maintains hydrolytic and thermal stability while improving impact performance at low temperatures. The low temperature toughness of polycarbonate and PC/ABS blends can be significantly improved with low dosage levels of PARALOID™ EXL 2691J. As the impact retention of polycarbonate can be improved considerable with the addition of PARALOID™ EXL 2691J.
