A New Process for FRP Auto Parts

Large, injection molded, polyester premix parts with increased toughness

“…More recently, reactive impact modifiers have been introduced which actually take part in the crosslinking reaction thus becoming an inte g a l part of the final polymeric matrix. Although used in low levels (1)(2)(3)(4)(5)(6)(7)(8)(9)(10)(11)(12) phr of a 50% solution in styrene), the reactive modifiers add a significant degree of flexibility and practical impact resistance to injection molded parts without significantly sacrificing tensile strength, flexural strength, or surface quality (see Table 1). …”
