Abstract
ABSTRACT This study investigates and quantifies the water absorption behaviour of hydrophobic carbon black in the 75IIR/25EPDM blend by keeping 5 × 2.5 × 0.2 cm samples in distilled water over three months. We utilise HAF (N-326) at concentrations of 50, 60, and 70 phr as filler for 75IIR/25EPDM blend. Samples are masticated carefully and then molded under a hot hydraulic press. The effect of water absorption by un-filled and filled samples is described using two fitting models: the logistic and the two-exponential growth models. The results show the water absorption has non-Fickian behaviour for all samples, and water uptake increases continuously. The rate of the uptake is found to be minimum for the sample with HAF-concentration of 60 phr.
期刊介绍：
Plastics, Rubber and Composites: Macromolecular Engineering provides an international forum for the publication of original, peer-reviewed research on the macromolecular engineering of polymeric and related materials and polymer matrix composites. Modern polymer processing is increasingly focused on macromolecular engineering: the manipulation of structure at the molecular scale to control properties and fitness for purpose of the final component. Intimately linked to this are the objectives of predicting properties in the context of an optimised design and of establishing robust processing routes and process control systems allowing the desired properties to be achieved reliably.
