The effect of Alkanolamide (ALK) loading on properties on three different types of carbon
black (CB) - filled rubbers (SMR-L,, ENR-25 and SBR), was investigated. The ALK loadings
were, 1.0 3.0 5.0 and, 7.0 phr. It was found that ALK gave, cure enhancement. Better filler
dispersion and greater rubberefiller interaction. ALK also enhanced modulus hardness
resilience and tensile,,, Strength.Especially up to 5.0 phr of loading in SMR-L and SBR
compounds and at, 1.0 phr in ENR-25 compound. Scanning electron microscopy. (SEM)
proved that each optimum ALK loading exhibited the greatest matrix tearing line and
surface roughness due to better. Rubber - filler interaction.
