Natural Rubber (NR) is a highly elastic hydrocarbon polymer derived from natural latex tapped from Hevea brasiliensis trees.
Chemically, it is cis-1,4-polyisoprene, a linear polymer that crystallizes under strain, giving it exceptional resilience, tensile strength, and toughness.
Our Natural Rubber elastomers are engineered for outstanding resilience and elasticity, delivering rapid elastic recovery and high energy return (up to 80% rebound) — ideal for vibration and shock isolation applications. NR compounds exhibit excellent dynamic fatigue and crack-growth resistance, performing exceptionally well under cyclic loading and mechanical vibration.
Natural Rubber’s mechanical strength is further enhanced by strain-induced crystallization, providing superior tear and abrasion resistance and outstanding fatigue endurance under dynamic service. Its excellent low-temperature flexibility allows functional elasticity down to –75 °F (–60 °C). NR also bonds easily to metals and fabrics through multiple processing techniques, enabling high-strength rubber-to-metal assemblies such as mounts, couplings, and vibration isolators.
In addition, NR is a biodegradable, renewable material sourced from natural latex — an environmentally sustainable elastomer option.
