Physical Properties Of Rubber Ball

In this lesson students will explore the physical properties of a variety of balls and how they bounce i e their bounciness or elasticity the point of the activity is not necessarily to have students arrive at a precise explanation for the phenomena they are investigating but to provide students with the following experiences.

Physical properties of rubber ball.

The marble will bounce the least high. The rubber materials selected by designers and technical buyers should meet all their application requirements. Galsports exercise ball 45cm 75cm anti burst yoga ball chair with quick pump stability fitness ball for birthing core strength training physical therapy 4 6 out of 5 stars 1 205 17 99 17. Polybutadiene butadiene rubber br is a synthetic rubber polybutadiene rubber is a polymer formed from the polymerization of the monomer 1 3 butadiene polybutadiene has a high resistance to wear and is used especially in the manufacture of tires which consumes about 70 of the production another 25 is used as an additive to improve the toughness impact resistance of plastics such as.

10 10 2016 origin pidegree gloves a concentration the concentration of the latex is expressed as the total solid content and the dry gel content. For elliminating chatter or vibration in cabinetry rubber balls are used. However the knowledge of rubber s physical properties and their measurement is critical for compound selection. If the cloth cover wears down to say 2 mm thickness the ball will become softer.

The inherent physical characteristics of elastomers can be modified through compounding. Properties of rubber balls. The total solid content refers to the content of. 605 author pidegree gloves publish time.

Rubbers are a fascinating class of materials because several of their unique properties have no parallel in the nonpolymeric material world. 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. The rubber is about 3 mm thick and the cover is also about 3 mm thick.

In this article the molecular origins for this unique behaviour will be addressed. Repeat steps 11 and 12 for the ping pong ball. Elasticity occurs because the chains can be stretched. A used ball is generally softer than a new ball since ball stiffness depends on the wall thickness and the amount of air inside the ball.

The dry content refers to the content of dry rubber in the latex. Vulcanization or curing produces chemical links between the loosely coiled polymeric chains. Judy scotchmoor and lisa white. 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.
