Polypropylene suture, a synthetic non-absorbable monofilament, is widely utilized in diverse surgical techniques. Its numerous advantages, including minimal tissue reaction and superior tensile strength, make it a preferred choice over natural fiber sutures with a lower risk of infection. Due to its inert nature, it remains strong without being absorbed by the body, making it ideal for cardiovascular and ophthalmic surgeries.

These sutures are also suitable for closing skin incisions and internal tears that require extended support. Their flexibility, ease of handling, and low friction between tissues make them a go-to option for surgeons seeking precision and durability in tissue approach and ligation. However, as they are non-absorbable, they must be removed or permanently retained within the body when used. Overall, the use of polypropylene sutures showcases the advancements in surgical materials, offering a dependable and secure alternative for wound closure.

The melting point of PVC (Polyvinyl Chloride) plastic pipe varies but generally falls within the range of 160°C to 210°C (320°F to 410°F). This variation depends on the specific formulation of the PVC material, including the addition of plasticizers, stabilizers, and fillers, which are used to modify the properties of the final product. Pure PVC has a melting point closer to the higher end of this range. It's crucial to keep PVC below its melting point during processing to prevent decomposition, which can release hazardous hydrochloric acid gas. In applications, understanding the thermal properties of PVC is essential for ensuring that it functions correctly under the expected temperature conditions, avoiding issues like deformity or loss of mechanical strength.
