SEBS/PP-blended TPE is ideal for automotive interior skins due to its elasticity, weather resistance, and eco-friendliness. An experiment examined its formula's impact, finding SEBS/PP ratio significantly affects mechanical properties, fluidity, and wear resistance. Increasing PP content improved mechanical performance within a range, but higher filling oil content increased stickiness and decreased abrasion resistance. Optimal performance was with a SEBS ratio of 30/70 and linear/star-shaped SEBS ratio of 70/30.
