Product Specification

20MM Valves / Bearings Silicone Rubber Ball 70 Shore High Temprature Resistant

Rubber balls are spherical shaped balls having varied applications. Right from a small toy ball to large industrial applications, the use of rubber balls is seen. They are used as check or ball valves, bearings, and in other applications. Rubber as an elastomeric material is a synthetic or processed material that can be shaped into many forms. The balls are manufactured in a number of different colors and elastomers/rubber types, depending on the application.

Buying Tips
Performance specifications for rubber balls are:

• Size or diameter: The width or outer diameter (OD) of the ball.
• Use temperature: The temperature range to which the rubber material can be exposed without degradation of structure or other required end-use properties.

• Types of Rubber Used in Rubber Balls

• Natural Rubber
• Nitrile Rubber (NBR)
• FKM
• Neoprene
• Silicone Rubber (SiR)
• Butyl Rubber (IIR)
• Isoprene Rubber (IR)

  Types of rubber balls

  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 used in check valves and many more. 
   

  Uses of rubber balls

  Rubber balls are used for a wide variety of uses like for screen cleaning and screen de-blinding, air restriction, check valves. Rubber balls are used in FDA uses, for games and sports, for light load-bearing applications. There are rubber balls used in the flow control and flowmeter applications in the pharmaceutical, food and chemical processing industries. For elliminating chatter or vibration in cabinetry, rubber balls are used.
   

  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 elongatio
