ABS Black Granules are an engineering polymer that has great fluidity to take up any shape and provides a good shine and color. It stands out for its strong nature, thermal stability, and its ability to conform to any rigid matrix. ABS Granules have great fluidity to take up any shape and provide a good shine and color. It is made by polymerizing acrylonitrile and styrene, along with the presence of polybutadiene. Its proportions vary from material to material but the composition makes the ABS Black Granules more robust than pure polystyrene.
