AI Technical Summary
Technical Problem
While existing electric motorcycle tires reduce rolling resistance, their wet grip and wear resistance are often compromised, and their tensile strength is insufficient, leading to safety hazards and reduced range.
Method used
It uses a specific ratio of Bio-IBR6401 bio-based itaconic acid ester rubber, EVEC®236 compound and EVEC®409 compound in synergy, combined with three types of carbon black with different surface areas and oil absorption values, and compounded with three accelerators to form a dense cross-linked network, which improves tensile strength and grip.
Benefits of technology
It achieves a balance between high grip, low rolling resistance and excellent wear resistance, ensuring the stability and safety of electric motorcycles in both sunny and rainy weather.
