Unusual flowability,toughness and hydrolytic resistance

摘要

POCAN~(R)DP B 3225 XF and Pocan~(R)DP B 3235 XF are two new grades with particularly high flowability in Lanxess Deutschland GmbH's range of Pocan~(R) polyesters.The new products,based on polybutylene terephthalate(PBT),are being marketed under the name Pocan~(R)XtremeFlow."For the shearing rates typically encountered in injection molding,the melt viscosity of Pocan~(R) DP B 3235 XF,for example,is only around half that of our standard PBT,PocanR B 3235.
