DEVELOPING MATERIAL, MEDICAL TUBE AND PREPARATION METHOD THEREFOR

WIPO Patent Application WO/2020/062987

A1

A developing material, a medical tube, and a preparation method therefor. The preparation method comprises the following steps: S1: dissolving a coupling agent in an ethanol solution, adding an ultra-fine powder developer, stirring, washing and drying to obtain a modified ultra-fine powder developer, wherein the particle diameter of the ultra-fine powder developer is 0.35-0.8 μm; S2: mixing a medical polymer material and the modified ultra-fine powder developer to obtain the developing material. The prepared developing material not only has a material developing function, but may simultaneously improve the elastic modulus, breaking strength and flexural modulus of the medical polymer material, has good mechanical properties, and expands the application of medical polymer material hollow fibers in the field of high-end microtraumatic interventional medical treatment products; in particular, the prepared developing material is applied to a conveyor, which may improve the pushing and torque performance of the conveyor, so that the conveyor may be applied to products such as a super-sliding guide wire, heart valve, guide catheter, degradable conveyor balloon and the like.
