Application：
In the automotive industry, Antioxidant 1520, when added at 0.5% to the tread compound of high-performance radial tires in combination with a nano-silica reinforcing system, enables the tire to maintain a tread hardness change within ±3 Shore A after 300,000 km of driving, effectively delaying rubber aging. When used in TPO materials for automotive dashboards, it is compounded with ultraviolet absorbers to maintain good surface gloss and scratch resistance after 2,000 hours of aging at 80°C and 90% humidity.
In the electronics sector, adding it to PVC insulation layers significantly enhances thermal stability, with insulation resistance retention reaching 92% after aging at 150°C for 168 hours, while inhibiting hydrogen chloride gas generation to meet RoHS requirements. For EPDM-based connector sealants, it ensures elasticity and sealing performance within -40°C to 125°C.
In construction, 0.3% Antioxidant 1520 strengthens the weather resistance of SBS-modified asphalt waterproof rolls, maintaining over 80% tensile strength after 500 hours of artificial climate aging. For EPDM door/window seals, it preserves elasticity and compression set resistance after 5 years of outdoor exposure. In sports goods, it collaborates with wear-resistant additives in TPU soles to enhance abrasion resistance by 20% and fatigue resistance, while preventing sweat/friction-induced discoloration and surface hardening in TPE fitness equipment grips to retain comfort.
