Explanation

Polysulfone is used as filtration media. The pore size can be very small, down to 0.2 µm or less for use in filter sterilization. A major application of polycarbonate is the production of Compact Discs, DVDs, and Blu-ray Discs. Acrylonitrile butadiene styrene (ABS) is commonly used in rapid prototyping extrusion-based 3D printers. Nylon 6-6 is frequently used when high mechanical strength, great rigidity, and good stability under heat is required. It is used for ball bearing cages, electro-insulating elements, pipes, profiles and various machine parts.
