Detailed Solution

Property	Natural Rubber	Vulcanized Rubber
Tensile Strength	Moderate, can break under high stress	Higher, due to cross-linked sulfur bonds
Elasticity	Very high, stretches easily but recovers slowly under load	Improved elasticity with faster recovery and better shape retention
Hardness	Soft and sticky	Harder and more resistant to deformation
Abrasion Resistance	Low, wears out quickly	Significantly improved, resistant to wear and tear
Tear Resistance	Moderate, tears easily	Higher, tougher against cuts and tears
Compression Set	High, deforms permanently under constant load	Low, maintains shape under compression
Temperature Resistance	Poor, softens at high temperatures, becomes brittle at low	Much better, can withstand wider temperature range
Aging & Oxidation Resistance	Low, degrades quickly when exposed to air, ozone, or sunlight	High, more durable due to sulfur cross-links
Resilience	Good, but loses energy under repeated stress	Better, recovers energy more efficiently under cyclic loading
