A buffer tube for use in a fiber optic cable is disclosed. The buffer tube has a flexural modulus greater than about 180 kpsi and less than about 370 kpsi, which results in a buffer tube having good crush resistance and flexibility. A particularly useful buffer tube material is an alloy of polypropylene and polyphenylene oxide, which may contain solid fillers.
