Ethylene Vinyl Acetate rubbers (EVA) are recognized for their excessive temperature durability, mechanical strength, super compression set, exact abrasion and wear resistance, low temperature flexibility, low permeability to gases, vibration damping and oil-water resistance. By addition of small proportions of Thermoplastic Polyurethane (TPU) to EVA an enhancement can be acquired in the tensile strength, elongation at break, tear strength and compression set. Additionally improved mechanical properties may additionally be accomplished barring compromising with the other vital bodily houses of EVA such as its low density. In this paper utilization of TPU grafted EVA (EVA-g-TPU) as a compatibilizer for the guidance of EVA/TPU combination has been implemented. Graft addition reaction of EVA-g-MAH with TPU might also result in the formation of the EVA/TPU with top-quality properties and compatibility. Use has been made of an EVA with 28% vinyl content in this case. The blending can be achieved on a twin screw extruder. The characterization of the blend will be based on Fourier Transform Infrared Radiation (FTIR) Spectroscopy. The received closing combination is estimated to be in the form of EVA / EVA – g – TPU / TPU. Similarly the blend of Fluoroelastomer (FKM) with Polypropylene (PP) has been carried out using a compatibilizer in the form of maleated EPDM (Ethylene Propylene Diene Copolymer), which is again a grafted copolymer.
