To facilitate the mixing and fabrication processes as well as to obtain the elastomeric properties of the TPVs, oil-extended MNR (OE-MNR) was first prepared by mixing the MNR with 20 phr of paraffinic oil in a dispersion kneader (Yong Fong Machinery Co., Ltd., Samutsakon, Thailand) with a capacity of 3 L at 80 °C.
