Kite Altitude World Record

12,000 meters of Ultra High Molecular Weight Polyethylene (UHMWPE) braided fibre or Dyneema® braid which is, weight for weight, the World's Strongest Fibre. Here is a big reel with a solid core and 3 mm aluminium reel ends. The line consists of 2 strengths joined by splicing. The inner line is 6,000 meters white, 131 kg breaking strain (289 lb) and 0.9 mm diameter braided Dyneema. The outer pink line is 6,000 meters, 86 kg breaking strain (192 lb) and 0.8 mm diameter braided Dyneema.

Structure of UHMWPE, with n greater than 100,000

Dyneema® derives its enormous strength from a proprietary gel-spinning process that results in extremely long, straight polymer chains.
Van der Waals forces are mostly responsible for the strength of UHMWPE polymer chains. Van der Waals forces include attractions between atoms, molecules, and surfaces, as well as other intermolecular forces.

Dyneema®, the world’s strongest fiber™

Dyneema® is an UHMWPE fiber. DSM invented it 20 years ago and it's been in production since 1990. The fiber is versatile with virtually numerous applications. The fiber is manufactured by means of a gel-spinning process that combines extreme strength with incredible softness. So what are the properties that make this fiber so special?
High strength/low weight – Dyneema® is 15 times stronger than steel, and 40% stronger than aramids on a weight-for-weight basis.
Low specific gravity (0.97) - Dyneema® floats on water and is ideal for lightweight solutions.
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.
UV resistant – Products made with Dyneema® fiber show strong resistance to photo degradation when exposed to UV light. The high UV resistance of the fiber ensures continuing high performance.
Moisture resistant - Dyneema® fiber is hydrophobic. It resists water absorption, providing an extra level of protection and durability.
High durability - Dyneema® fiber can withstand the harshest environments for a longer time. This is due to its inherent strength, and its resistance to many damaging chemical agents..

DSM Dyneema created the gelspinning process for manufacturing fibres from UHMWPE. The company continue to research new products and processes as well as improvement current products. There has been an evolution of improvements to Dyneema fibre including Dyneema® 65, Dyneema® 75 and most recently, Dyneema® SB71. Quality control at it's plants is a very high priority and DSM Dyneema protects the integrity of the Dyneema name closely to prevent illicit manufacture from eroding it's reputation and rights and to protect it's intellectual property.
DSM Dyneema has licenced several companies including Honeywell inthe USA and Toyobo in Japan.
