The mixture of two or more polymers to create a new material with different physical properties is known as blend or polymer blend.
Polymer blending has drawn attention as an easy and cost-effective method of developing materials that have versatility for commercial applications.
The properties of the blends are manipulated according to their end use by correct selection of the component polymers.
Typical Blends are PC+ABS, PA6+PA66 and ABS+PA.
The picture is showing a blend with amorphous (green) and semi-crystalline (purple) components plus additional fillers (blue).
