Polymer blend consists of two or more polymers blended together to form a material that combines the advantage of the individual base materials. In this work, the polymer blend coupons based on the nylon filament and Acrylic Styrene Acrylonitrile (ASA) were developed. The blends with various proportions of ASA and nylon created from the extrusion process and fused deposition modeling were subjected to UL-94 flammability test (vertical burn and horizontal burn). According to the results from this study, blending nylon with ASA improved the flame retardancy. The blends, regardless of the proportion of nylon, exhibited superior flame retardancy marked by a lower flame propagation rate and higher burn time than ASA. Increasing the nylon content also increased the elapsed burn time for the blend in the case of the vertical and horizontal burn test.

摘要

Polymer blend consists of two or more polymers blended together to form a material that combines the advantage of the individual base materials. In this work, the polymer blend coupons based on the nylon filament and Acrylic Styrene Acrylonitrile (ASA) were developed. The blends with various proportions of ASA and nylon created from the extrusion process and fused deposition modeling were subjected to UL-94 flammability test (vertical burn and horizontal burn). According to the results from this study, blending nylon with ASA improved the flame retardancy. The blends, regardless of the proportion of nylon, exhibited superior flame retardancy marked by a lower flame propagation rate and higher burn time than ASA. Increasing the nylon content also increased the elapsed burn time for the blend in the case of the vertical and horizontal burn test.
