ENHANCEMENT IN MECHANICAL PROPERTIES BY STYRENE MALEIC ANHYDRIDE(SMA) COMPATIBILIZER FOR ABS AND PA6 BLEND

PLASTIC ENGINEERING

Blend of ABS and PA6 material are investigated over a range of composition using a compatibilizer (KEMZER-SMA). Different composition of ABS and PA6 in varying ratio from 80:20, 60:40, 40:60, 20:80 with incorporating 2, 4, & 6wt % of compatibilizer and without compatibilizer. In general, incorporation of the compatibilizer can lead to high mechanical properties using different wt% ratio. Unlike the commonly used compatibilizer in ABS/PA6 blend, SMA is compatible with ABS polymer matrix core phase, polybutadiene rather than shell phase of SAN. By addition of small % of SMA can dramatically increase the MFI of the blend. This shows improved dispersion of ABS particles in the matrix that reduce the viscosity of the melt blend. The compatibility and interaction of the component in the blends were characterized by FTIR and MFI. A Blend of both polymers improves toughness, mechanical strength and dimensional stability with the help of SMA compatibilizer. The issues of compatibility and toughening of ABS/PA blend are discussed and current challenges are highlighted
