Polypropylene Plastic Balls
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 a melting point of 171ºC (340ºF)

Advantage |
Has good resistance, chemical resistance, low density (density less than water), low water absorption, the highest melting point of the thermoplastic with excellent electrical insulator and low dielectric coefficient, often used for floating capacity requirements, withblood transfusion, level calibration indicator. |
|
Application |
PP ball is mainly used for transfusion, level calibration indicator. |
POM Delrin plastic balls
POM, characterized by its high strength, hardness, and stiffness to ~40ºC., is intrinsically opaque white, but it is available in all colors. POM has a density of 1.410-1.420 g/cm³.
POM homopolymer is a semicrystalline polymer (75-85% crystalline) with a melting point of 175ºCelsius. The POM copolymer has a slightly lower melting point of 162-173ºCelsius.
