Acrylic Impact Modifier

Unmodified polymers viz, PVC, PMMA, PSSAN are brittle. Even PC,PA or PE will exhibit a brittle to ductile & limited impact strength, In order to satisfy end-use requirement for rigid applications, In Acrylic ( Impact Modifier ) in rigid PVC formulation, To get the required impact strength in rigid polymers. The quality of dispersion The adhesion to the polymer matrix The rubber domain particle size in the matrix The rubber glass transition temperature
