Synthetic Polyisoprene Rubber Market to Reach US $1.97 Bn by 2032
The global market for Synthetic Polyisoprene Rubber (IR) is projected to grow from about US $1,396.5 million in 2025 to approximately US $1,965.0 million by 2032, implying a compound annual growth rate (CAGR) of around 5.0 %.
IR is a man-made elastomer designed to mimic the properties of natural rubber, offering high elasticity, resilience, and tensile strength, and fewer impurities such as proteins that can trigger allergies.
Key growth drivers include growing use in the automotive sector, particularly tyres, engine mounts, bushings, and vibration control components, where IR’s fatigue and abrasion resistance make it attractive. The medical sector is also boosting demand, thanks to IR’s suitability for gloves, tubing, and other devices that need high purity and low allergenic risk.
Geographically, the Asia-Pacific region is expected to lead market growth, driven by rising vehicle production and healthcare infrastructure expansion in countries such as China and India. Meanwhile, North America and Europe will remain important for premium and specialised applications.
However, there are headwinds. Production costs for synthetic polyisoprene remain relatively high compared with natural rubber. Fluctuating feedstock prices and competition from other synthetic rubbers also weigh on widespread adoption.
For the tyre and rubber-component industry, these dynamics mean that while IR offers performance advantages, cost and supply chain stability will determine how quickly it is adopted at scale.
Editor’s View
For tyre-industry stakeholders, the projected growth of synthetic polyisoprene rubber is noteworthy. While traditionally dominated by natural rubber and more common synthetics, the rising appeal of IR, especially for high-performance or specialty tyres, is a signal that material sourcing strategies should evolve. Indian and other Asian-region tyre makers in particular should watch IR developments: keeping track of cost curves, feedstock shifts, and medical-grade production may give early movers an edge in offering premium products aligned with future sustainability and performance demands.
