Airtightness Additive MT‑IIR from HEWITT CHEMICAL is an advanced rubber antioxidant and effective ozoen protection agent tailored for inflation-resistant applications in IIR rubber compounds. Designed to enhance anti‑fatigue and anti‑flexing performance, MT‑IIR supports airtight sealing and structural resilience in hoses, tire inner liners, and sealing profiles. Ideal for B2B manufacturers seeking consistent quality, durability, and industry compliance.
Enhanced Thermal and Oxidative Armor
Airtightness Additive MT‑IIR functions as a powerful rubber antioxidant, protecting curing and cured IIR compounds from premature aging due to heat and oxygen exposure. It preserves elasticity and ensures airtight performance over prolonged service life.
Durable Surface Shield with Ozone Resistance
Acting as a proven ozoen protection agent, MT‑IIR forms a protective barrier to prevent ozone-induced cracking on exposed surfaces. This safeguarding extends airtight integrity and improves longevity in outdoor or pressurized environments.
Quinoline Antioxidant for Fatigue Strength
Leveraging quinoline antioxidant chemistry, MT‑IIR delivers robust anti‑fatigue and anti‑flexing resistance. It minimizes micro-cracking and rubbers tearing and wearing during mechanical deformation, boosting compound endurance.
Optimized for Airtight IIR Applications
Specially formulated for IIR-based inner liners, hoses, and sealing components, MT‑IIR enhances airtightness and pressure retention. It effectively reduces leaks and structural degradation under repetitive flexing and thermal cycling.
Safe, Scalable Production from HEWITT CHEMICAL
Manufactured under strict quality controls, MT‑IIR offers low-volatility handling, dust-safe processing, and batch consistency. As a trusted phenolic resin supplier, HEWITT CHEMICAL ensures reliable supply, compliance, and technical support for global B2B customers.
