Properties of rubber band.

Rubber elastic substance obtained from the exudations of certain tropical plants natural rubber or derived from petroleum and natural gas synthetic rubber. The rubber materials selected by designers and technical buyers should meet all their application requirements. A rubber band also known as an elastic band gum band or lacky band is a loop of rubber usually ring shaped and commonly used to hold multiple objects together the rubber band was patented in england on march 17 1845 by stephen perry. Mechanical properties of rubber ronald j.

In this article we will describe the physical properties of rubber that you will see on a physical property data sheets for elastomers that are tested to astm d2000 specifications. Because of its elasticity resilience and toughness rubber is the basic constituent of the tires used in automotive vehicles aircraft and bicycles. However the knowledge of rubber s physical properties and their measurement is critical for compound selection. The fine properties of silicone rubber 15 2 meeting the increasingly diverse and sophisticated needs of industry with the unique properties of silicone rubbers the main ingredients of shin etsu s silicone rubber compounds are unique raw silicone rubber gum and high purity silica.

Schaefer introduction rubber is a unique material that is both elastic and viscous rubber parts can there fore function as shock and vibration isolators and or as dampers although the term rubber is used rather loosely it usually refers to the compounded and vulcanized. Rubber elasticity refers to a property of crosslinked rubber. Written by dale t. Rubber is quite stretchy as indicated by the nature of rubber bands.

Elasticity occurs because the chains can be stretched. Silicone rubber compounds have characteristics of both. It can be stretched by up to a factor of 10 from its original length and when released returns very nearly to its original length. Rubber is a member of a larger class of materials called elastomers and it is difficult to overestimate their economic and.

I have described what the property is why it is important and how you test it. Named for its property as an eraser to rub out pencil marks rubber is widely used. It s also tough tires resists water and chemicals gloves elastic rubber bands and much more. Most rubber bands are manufactured out of natural rubber or especially at larger sizes elastomer and are sold in a variety of sizes.

This can be repeated many times with no apparent degradation to the rubber. Rubber is also water resistant and is used as a seal around waterproof cellphone cases. Vulcanization or curing produces chemical links between the loosely coiled polymeric chains. The inherent physical characteristics of elastomers can be modified through compounding.

All rubberlike materials are polymers which are high molecular weight compounds consisting of long chains of one or more types of molecules such as monomers. Physical properties of rubber.
