What are elastomers give its applications?
Elastomer are used for rubber tires and tubes for vehicles, motorcycles, bicycles and recreational vehicles, lawn mowers and other yard work vehicles, belts, hoses, gloves, matting, toy balloons, rubber bands, adhesives and pencil erasers.
What are elastomers explain with stress strain curve?
An elastomer is a polymer with viscoelasticity (having both viscosity and elasticity) and very weak inter-molecular forces, generally having low Young’s modulus and high failure strain compared with other materials. The term, which is derived from elastic polymer, is often used interchangeably with the term rubber.
What type of elastic stress strain Behaviour is shown by rubber?
nonlinear elastic behavior
Rubber-like materials exhibit a very particular mechanical behavior when submitted to external loads. They show a nonlinear elastic behavior, therefore the relationship between stress and strain is not constant over the strain domain [1][2][3] [4] . …
Where are elastomers used?
Elastomers are used in the production of many of automotive products, including the following: Tires: Tires are made with a variety of synthetic and natural elastomeric materials, which help give them excellent flexibility and durability on the road.
What are the advantages of elastomers?
Custom Molding – The first, and most obvious benefit is that elastomers are highly customizable in size, shape, flexibility, and color. Elastomeric products such as polyurethane and urethane formulations quickly churn out precisely accurate and affordable parts and coatings made to customer specs.
What are the main characteristics of elastomers?
What are the main characteristics of the elastomer?
- Abrasion resistance. The thermoplastic elastomer performs high resistance when exposed to intense attrition, showing durability and flexibility.
- Toughness.
- Resistance and flexibility.
- Compression characteristics.
- Types of elastomers.
What are the properties of elastomers?
Elastomer properties include resilience — some elastomeric materials can be stretched repeatedly to twice their length and return to their original shape. They provide flexibility from their polymer composition, above glass transition temperature (Tg) for end-use requirements, and don’t melt in high temperatures.
What are the special features of elastomers?
Elastomers are polymers that are having a viscosity as well as elasticity and therefore are known as viscoelasticity. The molecules of elastomers held together by weak intermolecular forces, generally they exhibit low Young’s modulus and high yield strength or high failure strain.
Which of the following material is most elastic?
The correct answer is Steel. Steel is the most elastic material. If the object is elastic, the body regains its original shape when the pressure is removed. Steel having the steepest linear stress-strain curve among all.
What is plastically deformed?
Plastic deformation is the permanent distortion that occurs when a material is subjected to tensile, compressive, bending, or torsion stresses that exceed its yield strength and cause it to elongate, compress, buckle, bend, or twist.
What is the importance of elastomers for product design?
What is elastomer PDF?
An elastomer is a polymer with the property of elasticity. In other words, it is a polymer that deforms under stress and returns to its original shape when the stress is removed. The term is a contraction of the words “elastic polymer.” There are many types of elastomers, most of which are rubbers.
