Physical Property 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 property 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. It is a good all purpose type of rubber in part because it has a good balance of chemical and physical properties. The inherent physical characteristics of elastomers can be modified through compounding. Zinc oxide is an inorganic compound with the formula zn o zno is a white powder that is insoluble in water.
Vulcanization or curing produces chemical links between the loosely coiled polymeric chains. According to an answer about rubber bands and elasticity on the u s. Elasticity occurs because the chains can be stretched. The hindu explains that wires that are in danger of touching each other are covered with insulated coatings made from rubber to prevent short circuits from happening.
Rubber is quite stretchy as indicated by the nature of rubber bands. A physical change is any change in any physical property of a substance not in the substance itself. Its ability to extend to long lengths and then return to its original shape demonstrates the elastic property of rubber. It is used as an additive in numerous materials and products including cosmetics food supplements rubbers plastics ceramics glass cement lubricants paints ointments adhesives sealants pigments foods batteries ferrites fire retardants and first aid tapes.
However the knowledge of rubber s physical properties and their measurement is critical for compound selection. Written by dale t. I have described what the property is why it is important and how you test it. 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.
Examples breaking a piece of clay stretching a rubber band melting ice into liquid water dry ice sublimating into gas. The rubber materials selected by designers and technical buyers should meet all their application requirements. Rubber is also water resistant and is used as a seal around waterproof cellphone cases. Then release the band.
