Rubber: 1. Elasticity: Rubber is known for its high elasticity, allowing it to stretch and return to its original shape. 2. Insulation: Rubber is a good insulator of electricity and heat, making it useful for electrical insulation and protective clothing. 3. Water resistance: Rubber is resistant to water and moisture, making it suitable for use in waterproof products. 4. Abrasion resistance: Rubber is resistant to wear and tear, making it durable and long-lasting. 5. Chemical resistance: Rubber is resistant to many chemicals, making it suitable for use in chemical processing and storage.
Copper: 1. Conductivity: Copper is an excellent conductor of electricity and heat, making it widely used in electrical wiring and plumbing. 2. Ductility: Copper is highly ductile, meaning it can be easily drawn into wires or hammered into thin sheets. 3. Corrosion resistance: Copper is resistant to corrosion, making it suitable for use in outdoor applications and plumbing systems. 4. Malleability: Copper is highly malleable, meaning it can be easily shaped and formed into various products. 5. Recyclability: Copper is a highly recyclable material, with nearly all copper ever mined still in use today.
