Pei amorphous
WebPEI is an amorphous thermoplastic resin with amber transparency The resin is characterized by high deflection temperature (200°C at 264 psi), high tensile strength and flexural … WebBesides, B-BMSF@PEI converted crystal IBU into an amorphous form to increase the solubility. IBU/B-BMSF@PEI performed better wetting property compared to pure IBU and the physical mixture, which helped to dissolve the drug and would subsequently suggest an increase in absorption and bioavailability of the poorly soluble drug.
