The application of high melting point protective wax in the sidewall compound of semi-steel radial tire was studied. Compared with regular protective wax, the content of isoparaffin and the content of paraffin molecules with more than 35 carbon atoms in the high melting point protective wax were higher, and thus its melting temperature and viscosity were higher. As a result, the high melting point wax could form a better protective film. The experimental testing results showed that compared with the compound filled with 2 phr of regular protective wax, the compound with 1 phr of high melting point protective wax possessed better ozone resistance, while maintaining similar processing properties, similar physical properties before and after thermal aging, and similar weathering resistance. Besides, using high melting point protective wax to replace part of the ordinary protective wax, the wax blooming of the tire during summer storage could be resolved.
