Non absorbable sutures are made of synthetic materials that do not break down in the body. They are used to hold a wound closed or to reinforce an area of tissue to prevent tearing.
Non absorbable sutures are used to hold tissues together after an incision has been made. They are often made out of nylon, but they can also be made out of other materials such as polypropylene or polyester. The type of material used depends on what kind of tissue it will be holding together and how long you want the stitches to last before they dissolve naturally over time.
