The dropper cap is a black PP plastic 20-400 semi-ribbed skirt dropper assembly with a rubber bulb and a 77.7 mm glass pipette. Dropper assemblies are composed of a number of parts: the cap, the bulb, and the pipette (tube). Dropper assemblies are used with liquids that require precision and intricacy when using the product. Polypropylene (PP) is marked with the resin identification code of 5. PP is less flexible than LDPE, somewhat stiffer than other plastics, reasonably economical, and can be translucent, opaque, or of any color. PP has very good resistance to fatigue and has an extremely high melting point (320 degrees Fahrenheit or 160 degrees Celsius).
