High initial tensile strength, guaranteed holding power through the critical wound healing period. Smooth passage through tissue, easy handling, excellent knotting ability, secure knot tying: Tensile strength retention, guaranteed holding power Indications: For all surgical procedures especially when tissues that regenerate faster are involved.
List of some addition polymers and their uses Polymer Abbreviation Properties Uses Low-density polyethylene: LDPE: Chemically inert, flexible, insulator: Squeeze bottles, toys, flexible pipes, insulation cover (electric wires), six-pack rings, etc. High-density polyethylene: HDPE: Inert, thermally stable, tough and high tensile strength
The ultimate tensile strength of a material is an intensive property; therefore its value does not depend on the size of the test specimen.However, depending on the material, it may be dependent on other factors, such as the preparation of the specimen, the presence or otherwise of surface defects, and the temperature of the test environment and material.
Tensile strength: the ability of the suture to hold tissues in place without breaking. Elasticity: the ability of the suture material to adapt to changing tissues such as in cases of edema. Tissue reactivity: inflammatory response of the surrounding tissue that can cause materials to break down quicker and lose tensile strength.
When Kevlar is spun, the resulting fiber has a tensile strength of about 3,620 MPa (525,000 psi), [23] and a relative density of 1.44 (0.052 lb/in 3). The polymer owes its high strength to the many inter-chain bonds. These inter-molecular hydrogen bonds form between the carbonyl groups and NH centers.
High-strength steels have comparable yield strengths, and low-carbon steels have yield strengths much lower (around 0.5 GPa (73,000 psi)). Since steel has a specific gravity of roughly 7.8, these materials have a strength-to-weight ratios eight times that of high-strength steels.
Polymer degradation is a change in the properties—tensile strength, color, shape, or molecular weight—of a polymer or polymer-based product under the influence of one or more environmental factors, such as heat, light, and the presence of certain chemicals, oxygen, and enzymes.
In manufacturing high-quality composite parts, such as in the aerospace industry, FEP film can be used to protect parts during the curing process. In such applications, the film is called "release film" and is intended to prevent the curing adhesive polymer (e.g. the epoxy in a carbon fibre/epoxy composite laminate) from bonding to the vacuum ...
