Pump NBR Solid Rubber Ball High Elasticity Rubber Bouncing Ball

Rubber Balls Provide Excellent Sealing in Flow Control Applications such as Pumps and Check- Valves.

Rubber balls are of various types depending on their area of applications. There are molded rubber balls,

precision ground balls which are manufactured as per exact specifications. The commercial grade rubber balls

are produced as per industrial requirements. Ther are sponge rubber balls, rubber cleaning balls, rubber balls

Properties of Rubber Balls

• Depending on the rubber material, there are different properties of rubber balls. However,
• most rubber balls are manufactured with one or more of the following properties:
• Corrosion-resistant
• Soft
• Limited in heat resistance than metals, ceramics, glasses, or carbides
• Have good electrical insulation properties
• Good self-lubricating properties
• High degree of flexibility and elasticity
• High reversible elongation

Nitrile Rubber

Nitrile rubber (NBR, Buna-N) provides excellent resistance to petroleum oils as well as mineral and vegetable oil.

Nitrile rubber also offers strong resistance to heat aging - often a key advantage over natural rubber.

Nitrile rubber performs well in carburetor and fuel pump diaphragms, aircraft hoses, seals and gaskets as well as

oil-lined tubing. Due to its versatility, nitrile is used in applications involving not only oil and fuel resistance, but

those applications requiring resistance to heat, abrasion, water, and gas permeability.
