Physical Properties Of Rubber Band

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 band. It does better than natural rubber when it comes to resistance to heat ozone and oil but it also has a lower level of physical properties. When raw rubber is heated it becomes sticky and when it is in colder temperatures it tends to break just like the synthetic variety. 1 centre product design for sustainable development transilvania university of braşov. Named for its property as an eraser to rub out pencil marks rubber is widely used.
Physical properties of rubber. Written by dale t. The inherent physical characteristics of elastomers can be modified through compounding. Rubber tire pet hdpe mechanical properties.
The most common properties of rubber are its elasticity resistance to water and its use as an electrical insulator. Rubber density determines the specific gravity of the material such as foam rubber tpe plastic or un vulcanised rubber. Has markedly increased due to their well balanced physical and mechanical properties easy processability and relatively low cost. Vulcanization or curing produces chemical links between the loosely coiled polymeric chains.
It s also tough tires resists water and chemicals gloves elastic rubber bands and much more. Examples breaking a piece of clay stretching a rubber band melting ice into liquid water dry ice sublimating into gas. Elasticity occurs because the chains can be stretched. This test is often used for quality control of rubber materials in addition to the amount of specific ingredients required to produce a certain volume of material.
Rubber is bouncy sure but that s just the start of its numerous properties. 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. Color shape texture volume mass density a physical change is any change in any physical property of a substance not in the substance itself. Introduction global warming is a major environmental.
I have described what the property is why it is important and how you test it. It is a good all purpose type of rubber in part because it has a good balance of chemical and physical properties. However the knowledge of rubber s physical properties and their measurement is critical for compound selection.
