Dyneema vs polyamide The primary advantage of nylon over other materials is its 30% stretch to break, this makes nylon ideal in applications where energy absorption is a requirement. Upon request we can produce DX Cup with a core of Dyneema ® SK99 fibres Also known as Polyamide, this material when dry is slightly stronger than Polyester but will be weakened by up to 10% when it gets wet. 15 g/cm³ 1. Dyneema® also has a slightly smoother and more slippery surface. Nylon has good UV and abrasion resistance. Cost Dyneema is almost always more expensive than good old-fashioned nylon. Dyneema ® SK99: This is the strongest of all Dyneema ® fibres and beats SK78 with about 15% to 20% on strength. 0: $160: 7. 97) - Dyneema® floats on water and is ideal for lightweight solutions. Mar 24, 2025 · Polyamide: Polyamide: Y: 22. 1: Dyneema and Spectra are brand names for similar Ultra-high-molecular-weight As has already been said, Dyneema® slings are thin. But that comes with a price. In addition, because the process of dyeing polyethylene strands is very complicated, Dyneema® is mostly white (the colored edges and threads running through the sling are usually made of polyamide). 14: 53. Low specific gravity (0. 97 g/cm³ Friction Resistance Good OK Excellent Self lubricating Stretch High Low Very Low Creeps Colorfastness Superior Great Not Not Chemical Resistance Not good Excellent Good Excellent Arresting Force Excellent Good Not good Not good […] The repeated flexing of Dyneema degrades the fibers much quicker than nylon, especially when knots are tied in it. . 44 g/cm³ 0.

Dyneema quickdraws, slings and cam slings need to be replaced more frequently than the nylon equivalent. 37 g/cm³ 1. 15 kN (4980 lbf) Kordas: Iris 9: 9. DX Core 99, Powerline SK99. Excellent chemical resistance - Dyneema® is chemically inert, and independent studies have confirmed that Dyneema® performs well in dry, wet, salty and humid conditions, as well as other situations where chemicals are present. Therefore this grade is merely used for extreme situations where ultimate strength is of the essence.
