The document discusses various types of engineering plastics including polypropylene (PP), polystyrene (PS), acrylonitrile butadiene styrene (ABS), and polyamides (PA). It provides information on their properties, applications, and manufacturing processes. Key plastics discussed are PP, PS, ABS which are used in products like pumps, electronics, and automotive parts due to properties like strength, durability, and impact resistance. Polyamides are used in fibers and composites requiring toughness and flexibility.
