PARALOID KM-361 is an acrylic impact modifier suitable for use in a wide range of applications where the combination of outstanding natural weathering resistance and high impact strength is required. PARALOID KM-361 is based on latest acrylic impact modifier technology which is designed to provide an excellent balance of rheological properties. PARALOID KM-361 promotes fusion of formulations to a greater or lesser extent depending on the type of formulation. It minimizes the effects of shear stress on the rheology which has benefits like low post extrusion shrinkage, lower or zero levels of plateout, higher after-aging impact. PARALOID KM-361 provides high impact strength, outstanding natural weatherability and control of melt viscoelasticity making it suitable for advanced material applications requiring these key properties.
