Environment-friendly bio-based polymer hemodialyzer casing material

The invention discloses an environment-friendly bio-based polymer hemodialyzer casing material. The casing material is a blend which comprises the following raw materials in percentage by mass: 90-99% of environment-friendly bio-based polymer, 0.4-8% of plasticizer, 0.2-6% of lubricant, 0.1-2% of antioxidant, 0.2-3% of heat stabilizer and 0.1-4% of inorganic filler. The raw material environment-friendly bio-based polymer has the advantages of wide sources and the like, and is renewable and degradable. The prepared environment-friendly bio-based polymer hemodialyzer casing has higher biocompatibility, and can obviously lower the side effect of hemodialysis; and the waste hemodialyzer casing can be degraded by proper treatment, thereby greatly reducing the environmental pollution.
