Cyclopentene Market (2026): Key Players Powering Global Growth

MARKET INSIGHTS

Global Cyclopentene market was valued at USD 25.5 million in 2024 and is projected to reach USD 32.7 million by 2031, growing at an annual rate of 3.7% during the forecast period. While the pace of expansion is moderate compared to high‑tech chemical segments, consistent demand from polymer applications guarantees steady growth.

Cyclopentene (CAS 142‑29‑0) is a cycloalkene with the formula (CH2)3(CH)2, primarily produced through naphtha steam cracking. This colorless liquid serves as a critical comonomer in synthetic rubber and specialty plastics manufacturing. Its chemical properties—including insolubility in water and high vapor density—make it particularly useful in industrial polymerization processes.

The market’s progression is driven by Asia‑Pacific’s dominance (60% share), where manufacturers such as Zeon Corporation and Huangshan Basihui control over 80% of global production capacity. Recent capacity expansions in China, especially for ≥95% purity grades (74% market share), reflect growing demand from comonomer applications (69% end‑use share). However, stringent VOC regulations in Europe and North America present both challenges and opportunities for sustainable production innovations.
