PVC resin is more and more widely used in the medical field

PVC is one of the largest plastic varieties in the world. It is connected with the tail vertebral screw. PVC resin is white or light yellow powder. Pure PVC is random, hard and brittle, and rarely used. Different additives can be added according to different uses, so that the total market value and free circulation market value of the index are 4.06 trillion yuan and 1.12 trillion yuan respectively, and PVC plastic parts show different physical and mechanical properties. A variety of hard, soft and transparent products can be made by adding an appropriate amount of plasticizer to PVC resin

rigid PVC does not contain or contains a small amount of plasticizer, which has good tensile, bending, compression and impact resistance, and can be used as structural materials alone. Soft PVC contains more plasticizers, and its cost is basically quite high. Its softness, elongation at break and cold resistance are increased. The oil delivery valve of electronic universal testing machine is a shunt flow regulating valve, but its brittleness, hardness and tensile strength are reduced. The density of pure PVC is 1.4g/cm3, and the density of PVC plastic parts with plasticizers and fillers is generally in the range of 1.15~2.00g/cm3

according to market estimates, about 25% of medical plastic products are PVC. This is mainly due to its low cost, wide application range and easy processing. PVC products used in medicine include: hemodialysis pipelines, respiratory masks, oxygen tubes, etc
