This paper studies how the addition of Carbon nanotubes (CNT) influencing the properties, especially the mechanical properties and colorimetry of ethylene propylene diene rubber (EPDM)/SiO2 composites. The results show that the increased content of CNT can turn EPDM/SiO2 composites from lighter, redder, and yellower to darker, greener and bluer, respectively. The total color change (ΔE) of EPDM/SiO2 composites would be acceptable when the CNT content is below 3%. When the CNTs content reaches 4%, the tensile strength of EPDM is the maximum.

This paper studies how the addition and various content of Carbon nanotube (CNT) affecting the properties, especially the color difference of ethylene propylene diene rubber (EPDM)/ CaCO3 composites. The results show that the increased content of CNT can turn EPDM/CaCO3 composites from lighter, greener, and bluer to darker, redder and yellower, respectively. The total color change (ΔE) of EPDM/CaCO3 composites is acceptable, when the content of CNT is less than 2wt%. The optimum tensile strength of EPDM composites can be gained, when the content of CNT is 3%.

This paper evaluate how colorimetry change of ethylene propylene diene rubber (EPDM)/Aluminium oxide (Al2O3) composites when added with four types of crystallized resins. The results indicate that the filler Al2O3can turn EPDM control from lighter, redder, and yellower to darker, greener and bluer, respectively. The total color change (ΔE) of EPDM/Al2O3composites increase with the decrease amount of crystal lattices. EPDM/Al2O3/Polypropylene (PP) composite, with the highest crystallinity of PP, has little change of the lightness value and the total color change of EPDM compostes due to light scatter.

<div> <p>This paper examined the effect of addition of four polyolefins and mica on colorimetry of ethylene propylene diene rubber (EPDM) composites. The results illustrate that the addition of mica can turn EPDM control from lighter, redder, and yellower to darker, greener and bluer, respectively. The total color change (ΔE) of EPDM/mica composites changed with various types of polyolefins. Ethylene alpha olefin (POE) with lowest crystallinity decrease the Δa of EPDM/mica composites to the greatest extent, while EPDM/mica/Polypropylene (PP) composite, with highest crystallinity of PP, has little change of the lightness value.</p> </div>

In this study, tensile properties, thermal stability and morphology of polypropylene/ethylene propylene diene rubber/wollastonite (PP/EPDM/wollastonite) thermoplastic elastomer composites were tested and evaluated as a function of their compositions in comparison with PP/EPDM blends and native PP. PP was melt mixed with two loadings of EPDM (20 and 30% (w/w)) and for the composites each of these with three loadings of wollastonite (10, 20 and 30 parts by weight per hundred of the PP/EPDM resin) on a twin screw extruder and then injection molded. Both PP/EPDM blends provided a higher elongation at break but a lower tensile strength and Young’s modulus as compared with those of the neat PP. However, the addition of wollastonite microparticles (particle size of 1200 mesh) into the blends increased the Young’s modulus in a dose-dependent manner with increasing wollastonite loadings, whilst the tensile strength and elongation at break were decreased. Moreover, the thermal stability was improved by the presence of either EPDM or wollastonite in the PP matrix.
