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 incredibly versatile with virtually limitless 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..
Types of Dyneema®
Dyneema® derives its enormous strength from a proprietary gel-spinning process that results in extremely long, straight polymer chains. This exceptionally strong material is available in four major types.
- Dyneema® fiber, an Ultra-High Molecular Weight Polyethylene (UHMwPE)
- Dyneema Purity®, a medical grade fiber
- Dyneema® UD, a uni-directional sheet material for laminate composite construction
- Ballistic sheet, made from (UHMWPE) tape for laminate composite construction
