What is Nylon 6.6?
Nylon is a man made product. On the man made side, you will see primarily three types of thermoplastic. These are polyester, polypropylene, and nylon. Of the three types, nylon is by far the better choice.
Nylon is extremely versatile in its applications. It is highly resistant to
abrasion
and has excellent
resilience
.
Within nylon, there are two groups:
nylon 6
and
nylon 6.6
. Nylon 6.6 is the
premium thermoplastic
. It is the thermoplastic that is most often specified by professional architects and designers because it provides the
flexural strength
,
low-temperature toughness
and is the most
resilient
. Nylon 6.6 performs well in many applications such as wind turbine blades, automotive parts, and other fields that get a lot of wear and tear. Nylon 6.6 has additional molecules that give extra strength and the resilience compared to nylon 6. If you still have no idea what Nylon 6.6 is, do a search on google.

- High resistance to bending (over 150 degrees)
Adjustable blade degree with included degree adjuster
Increase/decrease blade angle by installing degree adjuster under the blades
"+" on the right side = Increase angle =
More
Torque, Less Speed
"-" on the right side = Decrease angle = Less Torque,
More
Speed
Please note this enhancement is only available from us. The so-called "defect" our competitor has claim is completely false and proves his ignorance in mechanical engineering.
Below are comparisons between the our blades and competitor's blades
Our white blades and black blades have the same supreme quality.
Below pictures are for demonstration ( Listing is for white Blades only):
Blade Surface:
Our Blades
Competitor's
Air-X
Pros:
- Made from
100%
new raw material
- 80% Nylon 6.6 thermoplastic
- 20% carbon fibre
- Only new materials will give the
shine
above
- Extremely flexible
- Low temperature toughness
- UV Resistance
Cons:
- Made from
brittle, recycled
plastic
- Fragments and debris can be found at the edge of the blade circled above - sign of recycled material
- Fragments will tear wind and create undesirable vortex behind the blades
- No shine at all
- The dull and dusty look are signs of
High fibre concentration
- High fibre will
prevent shrinking
, however, it makes the blade very
brittle
because plastics do not stick to fibres well, it will introduces
cracks
that will allow water to absorbed in. Due to the fact that water will
expand
when it freezes to ice,
two things
can happen:
In the less severe case, the surface of the blade will start to "
peel off
" like burnt skins
In the worst case, when there is enough peeling or a large enough crack, the blade will
snap
- Cracks can be found at the base of the blades
Pros:
- Made of new material, however it is not as shiny because of the
flow lines
*
*Directionally "off tone" wavy lines or patterns
Blade Angle:
Our Blades
Pros:
- To compensate the bending force from the wind, blades are slightly angled towards the direction of wind.
Competitor's
Cons:
- Poor Design, blades are angled away from wind. They might start hitting pole in strong wind
Air-X
Pros:
- To compensate the bending force from the wind, blades are slightly angled towards the direction of wind.
Base:
1. Mounting Base
Our Blades
Competitor's
Air-X
Pros:
- Mounting Base has been machined to make sure it will fit the hub perfectly
Cons:
- Mounting Base has not been machined so it is not flat
-
2mm
shrink / sink mark:
- Different angle for different blade will causes vibration
Pros:
- Mounting Base has been machined to make sure it will fit the hub perfectly
2. Mold
Our Blades
Competitor's
Air-X
Pros:
- The depth of our injection mold is
2.5"
-
Allows the shape of the bolt to be integrated into the blade
(
see dotted lines and picture below
)
- The mold is much
more expensive
than the thin ones our competitor's use
- Produce quality blades that will not shrink
Cons:
- Depth of the injection mold is approximately
1.25"
- Mounting base has to be
tilted at an angle
to compensate the lack of space
- Holes for bolts are
not integrated
due to restrictions set on the mold (ie: Mounting base is a
parallelogram
instead of rectangular)
- Holes are drilled after blade is produced and maybe
off centered
- Mold is much
cheaper
because it is thin
- Mold has an inferior design that compromise performance
Pros:
- Depth of the injection mold is approximately
1.5"
- Does not need to be thick because their blades is 22"
-
Allows the shape of the bolt to be integrated into the blade
(
see dotted lines and picture below
)
3. Edges
Our Blades
Competitor's
Air-X
Pros:
- Edges of the blade is smooth, no
Flash*
at all
*The terms "flash", "fins", and "spew" are used to refer to excess molding material that penetrates into mold gaps (i.e., between parting faces, slide push-out faces, and inserts, etc.) in a molten state.
Cons:
- Due to the lack of thickness / strength in the mold there is not enough clamping force to hold the two mold pieces together during injection
- Result is:
a 3mm
HUGE
Flash
- Totally compromise performance because blade is
deformed
Pros:
- Minor flashes can be found but they do not affect performance
4. Injection Point
Our Blades
Competitor's
Air-X
Pros:
-
3mm
Injection point
- Prevents Shrink marks
Cons:
- Approximately
2.5mm x 15mm
Injection point
- Mold is
damaged
and created Blister
- A bad place to be chose for injection (right on the edge of the blade)
- Performance is
compromise performance
due to wind drag
Pros:
-
4mm
Injection point
- Prevents Shrink marks
Blade Tip:
Our Blades
Competitor's
Air-X
Pros:
- Smooth, rounded blade tip to minimize wind drag
Cons:
- Flash has to be cut off from blade tip due to poor mold design
- Tip will tear incoming wind and create drag
Pros:
- Smooth, rounded blade tip to minimize wind drag
WARNING !!!
SHARP Edges, Handle with Care!
Rotating blades present the most serious mechanical hazard. The blades may be moving at velocities over 275 miles per hour (440 km/hr). At this speed, the tip of a blade is nearly invisible and can cause serious injury. Under no circumstances should you install the turbine where a
person could come in contact with moving rotor blades.
The installer of these blades is solely responsible for the use or misuse of these blades. We assume no liability for ANY injuries caused by these products.
