Medical plastics have a wide range of excellent properties to meet the diverse needs of the
medical industry. The basic requirements for medical plastics are chemical stability and biological safety, as they come into contact with pharmaceutical solutions or with the human body. Simply put, the components of the plastic material cannot precipitate out into the medicine or the human body and will not cause toxicity or damage to tissues or organs, and are non-toxic and harmless to the human body.
Commonly used medical plastic materials are PE, PP, PVC, PA, PTFE, PC, PS, PEEK, etc. PVC and PE use the largest amount, each accounting for 28% and 24%; PS accounts for 18%; PP accounts for 16%; engineering plastics account for 14%.
