1. a reciprocal relation between two or more things. 2. a statistic representing how closely two variables co-vary; it can vary from -1 (perfect negative correlation) through 0 (no correlation) to +1 (perfect positive correlation).
Downloads from Fluoropolymers as Polymer Processing Aid (PPA) DAIKIN PPA DA-910 is a new generation Polymer Processing Aid based on fluoropolymers, to improve processing of LLDPE and HDPE for demanding film applications.
In previous work1,2, flow visualization was used to understand how polymer processing additives (PPA) eliminate. sharkskin in linear low-density polyethylene (LLDPE). The PPA migrates to and coats the die wall, induces. slippage, and eliminates sharkskin. In this work, the interface between the PPA and LLDPE was further.
