What materials should be used for medical plastic products?
Medical plastic products are widely used in medical devices, healthcare products, etc. Choosing the right material can ensure the quality and safety of the product. In addition, it is necessary to take certain preventive measures during processing to ensure that the product meets the standard.
Selection of plastic materials:
1.Choose the appropriate material by combining the use environment and target group needs of the medical products. For example, for use in environments such as skin and mouth, a material with strong temperature resistance and corrosion resistance should be selected.
2.Consider the bending and compression performance of medical products. Medical devices need to be bent and compressed frequently, so the flexibility and strength of the material are very important.
3.Choose materials that meet the standards for medical products. Medical raw material needs to meet relevant standards and certifications, such as FDA and ISO.
4.Consider the processability of the material.
Common raw materials for medical products include the following:
PVC: PVC is a low-cost material with good corrosion resistance and electrical insulation. It is often used in disposable syringes and catheters.
PE: PE is a non-toxic, odorless, and tasteless material with good corrosion resistance and aging resistance. It is often used in infusion bottles and medical packaging.
PP: PP is often used in medical disposable gloves, and catheters.
PC: PC is a high-strength, rigid material with good impact resistance and corrosion resistance. It is often used in artificial joints, orthopedic products, etc.
PTFE: PTFE is often used in artificial heart valves and artificial blood vessels.
The selection of materials for medical plastic products needs to comprehensively consider the purpose, use environment and requirements of the target group of the products. During mass production, preventive measures should be taken, the temperature and pressure of the molding machine should be controlled, equipment such as the molding machine should be cleaned, operation details should be recorded, and strict quality inspection should be carried out.
