Release date:
2021/08/01
Medical plastics and ordinary plastics differ in material, performance, and usage. The following are the main differences between the two:
Material and Performance
Material: Medical plastics are usually made of medical grade resins such as polyphenylene sulfone (PPSU), polyethylene (PE), and polypropylene (PP), while ordinary plastics may use resins such as polyvinyl chloride (PVC) and polystyrene (PS). Medical plastics have higher requirements for raw materials and require strict quality control and inspection.
Performance: Medical plastics typically require good chemical stability, high temperature performance, electrical performance, as well as radiation resistance, non toxicity, odorlessness, and non aging characteristics. Ordinary plastics, on the other hand, place more emphasis on cost-effectiveness and practicality.
purpose
Medical plastics: Due to their excellent properties, medical plastics are widely used in fields such as medical devices, packaging materials, electronic devices, etc. They need to meet strict biocompatibility and sterility standards to ensure safe use in medical environments.
Ordinary plastics: Ordinary plastics are more commonly used in daily necessities, industrial products, films, fibers, and other fields. They have advantages in cost-effectiveness, durability, and practicality, but may not be suitable for medical environments that require special performance.
manufacturer's standard
Manufacturing standards: The manufacturing process of medical plastics needs to follow strict medical industry standards, such as ISO 10993, USP Class VI, etc., to ensure the safety and reliability of the products. The manufacturing standards for ordinary plastics are relatively loose, relying more on general industrial standards.
conclusion
There are significant differences between medical plastics and ordinary plastics in terms of material, performance, usage, and manufacturing standards. Medical plastics play an important role in the medical field due to their excellent performance and high standards of safety, while ordinary plastics are more common in daily life. When choosing plastic products, the decision to use medical plastic or ordinary plastic should be based on specific purposes and environmental requirements.
