It's heavy reading but this is Why Gosen braid is so good! it's made from SK71 Izanas fibre
Extremely High Strength and High Modulus
IZANAS™ has the highest level of tensile strength among commercialised organic fibers.
and High Modulus
IZANAS™ SK60 has the highest level value of the specific strength and modulus among commercialised organic fibers. Specifically, the brand-new IZANAS™ SK71 achieves a strength of 40cN/dtex or more.(c.a.4GPa)
Light Weight(low specific gravity)
The specific gravity of IZANAS™ SK60 is 0.97, which is the lowest value among super fibers and is lighter than water.
High Impact Strength
IZANAS™ SK60 has an extremely high impact strength. Due to its very high energy absorption characteristics, IZANAS™ SK60 is a suitable material for protective applications or sport composites applications.
IZANAS™ SK60 exhibits excellent flexibility and excellent abrasion resistance. Easy fabrication offers various textile applications.
Good Abrasion Resistance and Fatigue resistance
IZANAS™ has excellent abrasion and fatigue resistance. Due to its ability to be processed easily. (weaving, knitting etc.), this leads to wide applications for industrial use.
High Light Stability and Chemical Resistance
With no degradation due to water absorption, IZANAS™ SK60 is the ideal material for ropes or nets used in marine and off-shore applications. IZANAS™ SK60 has excellent light stability and chemical resistance in a wide pH range.
Good Light Stability
IZANAS™ shows good light stability due to its chemical and highly crystallized structure. IZANAS™ can be used without special covering or coatings.
Excellent Chamical Stability
IZANAS™ shows excellent chemical stability in a wide pH range, which prompts the application for chemical industries. Because there is no degradation from sea water absorption, IZANAS™ is an ideal material for marine and off-shore use.
IZANAS™ has a feature that it expands by lowering the temperature. IZANAS™ is an ideal material for cryogenic use that controls the dimension change of composites which is used under the room temperature and extremely low temperture.
Negative expansibility (in direction of fiber)
Plastic（FRP）reinforced with the following fibers
High heat conductivity
High heat conductivity
IZANAS™ has excellent vibration damping characteristics.
Fundamentally a form of polyethylene, IZANAS™ possesses the same chemical properties, making it an outstanding insulator.
As indicated by its chemical formula -(CH2-CH2)n- IZANAS™ is formed from carbon (C) and hydrogen (H). Consequently, even if IZANAS™ is burned all that remains is water (H2O) and carbon dioxide (CO2) and no harmful substances are released.
