Description
NR is primarily composed of polyisoprene (92–95%). As the most important natural elastomer, natural rubber occupies a central position in the global rubber industry due to its excellent overall performance and renewable characteristics. Through a special constant-viscosity process, this product offers stable viscosity and excellent processability, making it particularly suitable for large-scale industrial production.
Applications
Tire industry: Tread and carcass of truck tires, off-the-road (OTR) tires, and aircraft tires
Industrial products: Hoses, belts, anti-vibration products, seals
Medical field: Medical gloves, catheters, infusion bags
