Effect of Titanate Coupling Agent on the Mechanical Properties of Talc Filled Polypropylene
Journal Title: Academic Research International - Year 2014, Vol 5, Issue 3
Abstract
Composites of polypropylene filled with untreated and treated talc have been prepared. The surface modification of talc was done by using titanate coupling agent (TCA). The effect of this treatment on the interfacial adhesion of filler particles in the polymeric matrix was evaluated by mechanical analysis. The results obtained indicate that incorporation of non treated talc generally decreased the mechanical properties of the composites except the modulus. However, the use of treated talc increased the amount of filler that was incorporated in the polymeric matrix. Therefore the Mechanical properties such as tensile strength, flexural strength, elongation at break and impact strength are also improved.
