Anti-aging Additive SMQ from HEWITT CHEMICAL is a high-performance rubber antioxidant and ozoen protection agent based on quinoline chemistry. Designed for anti‑fatigue and anti‑flexing protection, SMQ extends service life by protecting rubber compounds in dynamic tire, hose, and seal applications. Ideal for B2B customers seeking durability, safety, and process reliability in industrial rubber manufacturing.
Extended Heat & Oxidation Resistance
Anti-aging Additive SMQ serves as a powerful rubber antioxidant, shielding rubber from thermal oxidation and age-related degradation. It slows heat-induced aging and preserves mechanical integrity under prolonged exposure to stress.
Powerful Ozone Protection Agent for Surface Integrity
SMQ acts as a reliable ozoen protection agent, forming a protective barrier that prevents ozone-induced cracking on rubber surfaces—vital in maintaining tire sidewall strength and hose resilience.
Quinoline Antioxidant Chemistry for Flexing Endurance
With fortified quinoline antioxidant properties, SMQ delivers superior anti‑fatigue and anti‑flexing performance, reducing rubbers tearing and wearing during dynamic bending and flexing cycles.
Ideal for Radial Tires and Heavy-Duty Rubber Applications
Engineered for radial tires, belts, hoses, and molded rubber parts, SMQ enhances compound endurance under mechanical stress. It prevents degradation and extends lifespan across industrial applications.
Safe, Reliable, and Industry-Grade Supply
Manufactured by HEWITT CHEMICAL under stringent quality protocols, SMQ offers low-volatility, dust-controlled handling, and consistent batch quality for scalable B2B production.
