“…[1,7,8] The main advantages of HTPCs are their higher mechanical properties, lower cost, ease of processability, and higher corrosion resistance. [4,5,[7][8][9] At this point, due to having a relatively lower processing temperature and affordable price, polypropylene (PP) is one of the most widely utilized thermoplastics in the automotive industry for HTPC applications. [10,11] On the other hand, interfacial bonding between the two components is a crucial parameter in achieving lightweight molded products with outstanding mechanical properties.…”
