Study on Effect of Wollastonite on the Thermal Properties of Nylon-6 and Morphological Analysis

Abstract

Nylon-6/Wollastonite composites were prepared with different concentration of 15, 25 and 35 % w/w of Wollastonite (acicular ratio-15-20%) by co-rotating twin screw extruder. Heat Deflection Temperature (HDT) of injection molded specimens of Nylon-6/ Wollastonite composites was evaluated; Differential Scanning Calorimetric (DSC) and Thermo Gravimetric Analysis (TGA) were studied for these composites. Scanning Electron Microscope (SEM) of tensile fractured sample was revealed uniformity of filler distribution throughout the matrix of Nylon-6/Wollastonite. Wollastonite improves Heat Deflection Temperature (HDT) of the Nylon-6/Wollastonite composites with reduction of product cost. The results suggest application of Nylon-6/Wollastonite in automotive parts, electric motors, gears, power tool housings etc. Due to fibrous nature, Wollastonite replacing short milled glass fibers for both thermoplastics & thermo-sets and short-fiber Asbestos which are hazardous to human health as well as difficult to handle.
