Top 10 Companies in the Antiscorching Agent PVI(CTP) Market (2026): Market Leaders Powering Global Rubber Innovation

MARKET INSIGHTS

The Global Antiscorching Agent PVI(CTP) market was valued at USD 123 million in 2024 and is projected to reach USD 172 million by 2032, growing at a CAGR of 4.7% during 2025‑2032.

Antiscorching Agent PVI (CTP), or N‑(cyclohexylthio) phthalimide, is a critical rubber additive that prevents premature vulcanization (scorching) during rubber processing. It works by delaying the onset of cross‑linking in rubber compounds, ensuring optimal processing conditions while preserving product integrity. The additive is widely used in both natural and synthetic rubber manufacturing, with prominent applications in automotive tires, industrial hoses, and footwear production.

Market expansion is driven by rising rubber consumption in the automotive and construction sectors, particularly in emerging economies. Regulatory scrutiny over chemical additives and volatile raw material costs present headwinds. The particles segment dominates due to superior handling characteristics, while China accounts for over 35% of global demand. Leading players such as Eastman Chemical and Dalian Richon Chem are scaling production to meet growing demand.
