A NEW BETA NUCLEANT MASTERBATCH FOR MINERAL FILLED AND UNFILLED POLYPROPYLENE APPLICATIONS

摘要

We have developed a unique, highly selective beta nucleant masterbatch that produces high levels of beta crystallinity, and high crystallization temperatures (Tc values). This masterbatch can also be used in polypropylene that already contains other additives which nucleate the alpha crystallinity, such as talc filled PP. The ability to beta nucleate talc filled PP offers the possibility of using beta nucleation to achieve both high stiffness and high impact strength in talc reinforced PP.
