Polypropylene (or PP for short) is an addition polymer that is produced from propylene, and is the second most widely manufactured polymer plastic in the world. The plastic is characterized by a low weight, high heat resistance, chemical inertness and high stretchability, which makes it highly suitable in the production of polypropylene balls for industrial purposes.
Polypropylene balls are commonly used in laboratory applications because of its resistance to swelling when exposed to water. Hollow, Polypropylene balls are also used in tanks to help slow evaporation and reduce heat loss.
Polypropene, is a thermoplastic polymer used in a wide variety of applications including packaging and labeling, textiles, stationery, plastic parts and reusable containers of various types, laboratory equipment, loudspeakers, automotive components, and polymer banknotes.
Polypropylene is mostly hard and flexible, particularly when copolymerized is with ethylene. Polypropylene is economical, and can be translucent when uncolored but is not as readily made transparent as polystyrene, acrylic, or certain other plastics. It is often opaque or colored using pigments. Polypropylene has great resistance to fatigue and has has a melting point of 171oC (340oF).
Polypropylene balls exhibit low corrosion levels and fatigue, and are able to withstand collisions well, enhancing their durability. They float well, are good electrical insulators, can be modified to resist degradation due to UV light, and are relatively easy to recycle.
