Polyisoprenes, natural (from trees) and synthetic, are noted for outstanding resilience, resistance to tear and abrasion, excellent elasticity, and flex fatigue resistance.
They also have excellent tensile strength characteristics and are operable in low temperature -65ºF (-54ºC) environments. They are not recommended for high heat, ozone, sunlight, petroleum or hydrocarbon environments.
The two isoprenes differ slightly; the purity of synthetic polyisoprene provides more consistent dynamic properties with better weather resistance. Synthetic polyisoprene’s lack of “tree” organics also gives a relatively odorless rubber.
Natural rubber, when compared to synthetic, provides slightly better properties in tensile strength, tear resistance, compression set, and flex fatigue resistance.
Butyl is a common term used for the isobutylene isoprene elastomer. As the name implies, butyl is comprised of isobutylene with a small amount of isoprene. It is known for its excellent resistance to water, steam, alkalis, and oxygenated solvents. Another outstanding characteristic is low gas permeation. It is capable of providing highenergy absorption (dampening) and good hot tear strength.
Good resistance to heat, abrasion, oxygen, ozone and sunlight are dependent upon the butyl polymer saturation level. Butyl however, displays poor resistance to petroleum oil, gasoline and hydrocarbon solvents.
