Improving the impact strength of compounds is the role of an important group of additives. Impact modifiers compensate for inherent brittleness, or embrittlement occurring at sub-zero temperatures, notch-sensitivity and crack propagation. The mechanism normally involves introducing a component that is elastomeric or rubbery in nature, which can absorb the energy of an impact or dissipate it. please looks at some of the options for the compounder wanting to improve toughness. #AIMIMPACT#cpe135a#mbs#environment#pvcimpactmodifier # #innovation Impact modifiers improve the impact strength of hard and semi hard PVC materials. We offer you a range of different PVC impact modifiers: Acrylic impact modifier Chlorinated polyethylene (CPE) Methyl methacrylate butadiene styrene resins (MBS) pls contact for more:mandyzhang@novistagroup.com
