Adsorption rate and tensile strength: Strength retention for at least 7 days. Maintains strength for 10–14 days [2] 84% at 2 weeks, 23% at 4 weeks [2] 80% at 2 weeks, 44% at 8 weeks. Complete absorption within 200 days [2] Structure: Multifilament: Multifilament: Braided: Monofilament Origin: Bovine serosa surface finish. Made by twisting ...
Synthetic materials include nylon, polypropylene and surgical steel all of which are monofilaments with great tensile strength. [2] Nylon (monofilaments, Dermalon, Ethilon) Description: polyamide; Advantages/disadvantages: Excellent tensile strength. However, poor handling and poor knot security due to high material memory.
Nylon 11 is seen to have increased dimensional stability in the presence of moisture due to its low concentration of amides. Nylon 11 experiences 0.2-0.5% length variation and 1.9% weight variation after 25 weeks of submersion in water in comparison to 2.2-2.7% elongation variation and 9.5% weight variation for Nylon 6.

Composed of an isotactic crystalline stereoisomer of polypropylene, Prolene sutures are intended to be durable and long lasting. They are dyed blue, allowing for easy visibility against skin and when operating. It is composed of a single filament. A polypropylene mesh Prolene product is used for repairing hernias and other injuries to the fascia.
English: Material comparison plot for Strength versus density. The guidelines for minimum weigth design are added. The strength for each group of materials is: Metal and polymers: Yield Strength; Ceramics: Compresive Strength; Elastomers: Tensile Tear Strength; and; Composites: Tensile Failure.
Polypropylene fibres are used as a concrete additive to increase strength and reduce cracking and spalling. [49] In some areas susceptible to earthquakes (e.g., California), PP fibers are added with soils to improve the soil's strength and damping when constructing the foundation of structures such as buildings, bridges, etc. [ 50 ]
Type 6,6 Nylon 101 is the most common commercial grade of nylon, and Nylon 6 is the most common commercial grade of molded nylon. [ 94 ] [ 95 ] For use in tools such as spudgers , nylon is available in glass-filled variants which increase structural and impact strength and rigidity, and molybdenum disulfide -filled variants which increase ...
The currently most-consumed engineering plastic is acrylonitrile butadiene styrene (ABS), used for e.g. car bumpers, dashboard trim and Lego bricks. Engineering plastics have gradually replaced traditional engineering materials such as metal, glass or ceramics in many applications. Besides equalling or surpassing them in strength, weight, and ...
