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 5 properties of rubber?

The following are the physical properties of rubber:

• Specific gravity.
• Abrasion resistance.
• Tear resistance.
• Compression set.
• Resilience.
• Elongation.
• Tensile modulus.
• Tensile strength.

What is the difference between rubber and elastomer?

Rubber and elastomer are words commonly used to mean any material with rubber-like properties. Elastomer is shorthand for elastic polymer. Elastomers are viscoelastic: sticky, very elastic polymers (plastics). Natural rubber is an elastomer made from latex, a milky tree sap.

What are the physical properties of rubber?

Physical properties of rubber include:

• Hardness.
• Tensile Strength.
• Tensile Modulus.
• Elongation.
• Resilience.
• Compression Set.
• Tear Resistance.
• Abrasion Resistance.

What are elastomers give two examples?

Examples of elastomers include natural rubbers, styrene-butadiene block copolymers, polyisoprene, polybutadiene, ethylene propylene rubber, ethylene propylene diene rubber, silicone elastomers, fluoroelastomers, polyurethane elastomers, and nitrile rubbers.

Which materials are called elastomers?

Elastomer, any rubbery material composed of long chainlike molecules, or polymers, that are capable of recovering their original shape after being stretched to great extents—hence the name elastomer, from “elastic polymer.” Under normal conditions the long molecules making up an elastomeric material are irregularly …

What are three properties of rubber?

Some of the material’s key characteristics are high tear and tensile strength, resilience, and resistance to abrasion, friction, extreme temperatures, and water swell.

What are the properties of silicone rubber?

Key material properties of silicone rubber include its fast curing and low compression set, its resistance to tearing, heat, water and oil, its transparency and electrical conductivity, and its overall strength and long life.

What are the physical and chemical properties of rubber?

Rubber is water repellent and resistant to alkalies and weak acids. Rubber’s elasticity, toughness, impermeability, adhesiveness, and electrical resistance make it useful as an adhesive, a coating composition, a fiber, a molding compound, and an electrical insulator.

What is properties of rubber?

Some of the material’s key characteristics are high tear and tensile strength, resilience, and resistance to abrasion, friction, extreme temperatures, and water swell. Typical uses include adhesives, flooring and roofing, gloves, insulation, and tires.
