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. Introduction global warming is a major environmental. Color shape texture volume mass density a physical change is any change in any physical property of a substance not in the substance itself. Physical mechanical properties of rubber.

It s also tough tires resists water and chemicals gloves elastic rubber bands and much more. The inherent physical characteristics of elastomers can be modified through compounding. Has markedly increased due to their well balanced physical and mechanical properties easy processability and relatively low cost. The most common properties of rubber are its elasticity resistance to water and its use as an electrical insulator.

Examples breaking a piece of clay stretching a rubber band melting ice into liquid water dry ice sublimating into gas. Written by dale t. It is a good all purpose type of rubber in part because it has a good balance of chemical and physical 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.

Vulcanization or curing produces chemical links between the loosely coiled polymeric chains. When raw rubber is heated it becomes sticky and when it is in colder temperatures it tends to break just like the synthetic variety. Elasticity occurs because the chains can be stretched. Physical properties of rubber.

Rubber is bouncy sure but that s just the start of its numerous properties. Typical rubber compound formulations consist of 10 or more ingredients that are added to improve physical properties affect vulcanization prevent long term dete rioration and improve processability these ingredients are given in amounts based on a total of 100 parts of the rubber parts per hundred of rubber. 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. However the knowledge of rubber s physical properties and their measurement is critical for compound selection.

Rubber tire pet hdpe mechanical properties. Rubber density determines the specific gravity of the material such as foam rubber tpe plastic or un vulcanised rubber. 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.
