New class of additives for improved mechanical properties in Polyethylene

12-Mar-15

An additive to improve mechanical properties in polyethylene such as yield strength, impact, modulus, and heat deflection temperature (HDT) without significantly affecting density - Dymalink 9100, has been developed by Cray Valley. The fast crystallization of polyethylene has typically limited nucleation as a way to improve mechanical properties. The low loading levels of Dymalink 9100 provide the first way to improve these properties without significantly increasing polyethylene density. “This is a truly novel development for the formulation of high-performance plastic products,” said Anthony Maroszan, global business development manager. “Adding just 1 to 2 percent of Dymalink 9100 can increase stiffness and HDT of high-density polyethylene by 20 to 30%.”
