Is féidir le modhnú fisiciúil PBT airíonna meicniúla an ábhair a fheabhsú agus a fheabhsú agus na hairíonna lasair lasair a fheabhsú.

Domestic modifications of PBT products are mainly focused on glass fibre reinforcement and flame retardant, especially PBT used as a high viscosity resin for optical fibre cable sheath covering material is more mature, but in terms of arc resistance, low warpage, high fluidity, high impact Ní mór neart, cobhsaíocht ardthoiseach, modal ard lúbthachta, etc. a neartú.
