Polyisoprenes, natural rubber, and synthetic rubber are noted for outstanding resilience, resistance to tear and abrasion, excellent elasticity, and flex fatigue resistance. Polyisoprenes also have excellent tensile strength characteristics and can operate in low-temperature environments. Polyisoprenes are not recommended for environments that contain high heat, ozone, sunlight, petroleum, or hydrocarbon.

 

Natural rubber, when compared to synthetic, provides slightly better properties in tensile strength, tear resistance, compression set, and flex fatigue resistance.
