PC+PBT blends combine polycarbonate's impact resistance with PBT's chemical resistance — solving the key weakness of pure PC (stress cracking from fuels, oils, and solvents). Makroblend UT grades are specifically formulated for unpainted automotive exterior applications where both low-temperature impact and fuel resistance are required.
